Running Qt apps on M1 ARM Macs

Apple is switching the processor architecture of it’s Macs. Again (I transitioned PerfectTablePlan from PowerPC to Intel some hears ago). This time to their own M1 ARM chips. Reports so far have been very positive about speed and battery life of the new processors. Obviously most current Mac software has been written for Intel Macs, so they are using the Rosetta2 emulation layer to run apps compiled for Intel Macs on the ARM chips. I’m not sure how much of a performance hit this causes, but clearly it would be better to run native ARM binaries on an ARM machine. Also Apple, being Apple, want to move everyone to ARM as quickly as possible. Tough luck if you just spent big bucks on a shiny new Intel Mac.

One of my customers emailed me that the latest version of my Hyper Plan visual planner, built with Qt 5.13.1, didn’t run on an new M1 Mac. I don’t currently have an M1 Mac to test it on. But my Easy Data Transform software , built with Qt 5.15.2, apparently works fine on an M1 Mac. So I recompiled Hyper Plan using Qt 5.15.2, and was told it now works. I have found a couple of minor differences in behaviour between Qt 5.13.1 and 5.15.2, but they are too obscure to go into here. Some Qt apps may still have issues on ARM.

Currently Qt is only available as Intel binaries. Efforts are in progress to be able to build Qt as M1 (ARM) binaries. When that is complete it should be possible to ship Qt applications as a ‘fat binary’ with both Intel and ARM executables, as I did with the PowerPC to Intel transition. I’m not sure if this is going to be supported on Qt 5 and 6 or just Qt 6.

Issues with Qt applications on macOS 11.0 (Big Sur)

In my previous post I wrote about the trials and tribulations of upgrading my iMac to macOS 11.0. Here I am going to list some of the issues I know about deploying Qt applications on macOS 11.0. More issues may subsequently come to light.

The QFileDialog::DontConfirmOverwrite flag is ignored when passed to QFileDialog::getSaveFileName(). Which means that you can’t use this flag and handle the message yourself, or you will end up with a double warning. This seems to have been an issue since macOS 10.15. It still isn’t fixed in Qt 5.15.2. It is annoying, but relatively easy to work around. The Qt bug report is QTBUG-39791.

QMessageBox::information() shows a placeholder icon instead of the information icon:

It is only cosmetic. But it looks shonky and Mac users tend to care a lot about this sort of thing. I can reproduce it in Qt 5.15.2. I don’t know of a workaround. The Qt bug report is QTBUG-88928.

QMessageBox::warning(), QMessageBox::information() etc show the default focus button incorrectly. For example:

QMessageBox::warning( this, "App", "text", QMessageBox::Ok|QMessageBox::Cancel, QMessageBox::Ok );


Again it is only cosmetic, but it looks jarring. I can reproduce it in Qt 5.15.2. I don’t know of a workaround. The Qt bug report is QTBUG-89133.

There are also some other styling issues. The Qt bug report is QTBUG-86513.

Dark Mode still doesn’t work properly for Qt apps.

There was an issue on macOS 10.15 where using QFileDialog::getSaveFileName() to save over an existing file could cause a crash. Thankfully that doesn’t seem to be an issue in macOS 10.11. The Qt bug report is QTBUG-83342.

Unfortunately issues with Qt on Mac are nothing new. I realize it is a big challenge for the Qt developers to keep such a large codebase up-to-date with so many continually evolving platforms. But the Mac version always feels rather neglected compared to the Windows version. I wish they would prioritise basic issues such as the above over adding whizzy new features, 80% of which most Qt developers probably never use. macOS 11.0 was released a couple of weeks ago and betas have been available for a while.

I would be interested to hear of the experience of other developers with macOS 11.0. Any other Qt macOS 11.0 issues I should know about? Please let me know in the comments.

Upgrading to MacOS 11.0 (Big Sur)

It is always a bit of fraught process upgrading a computer OS, especially for a development machine with loads of tools and libraries installed. So I try to do it as infrequently as I can get away with. On Windows I generally buy a new PC rather than upgrade OS. However glitches had been reported in Easy Data Transform on macOS 11.0 (Big Sur) and I wasn’t ready to abandon my 2017 iMac, so I decided to bite the bullet and upgrade it from macOS 10.13 to 11.0.

The initial upgrade of OS was straightforward enough. But when I tried to run Qt Creator the CPU shot to 99% and stayed there, making the machine unusable. A glance at Activity Monitor showed that several XCode related processes were going crazy. After a bit a Googling I managed to find this magic incantation to type into the terminal on a forum post:

defaults write DVTDisableMainThreadChecker 1

I was then able to rebuild my Qt-based products: Easy Data Transform, PerfectTablePlan and Hyper Plan using the existing installs of Qt 5.13.1 and Qt Creator 4.8.0.

I had to update some of the software I use:

  • DropDMG
  • Beyond Compare
  • SnagIt

Annoyingly, I had to buy an upgrade of SnagIt as the 2018 version doesn’t work on Big Sur. Even more annoyingly the upgrade costs nearly as much as a new licence, which feels predatory.

The Subversion command line no longer worked from the terminal, but that was easily fixed by adding /Applications/ to PATH in my .profile.

So far I haven’t been able to get the following to work:

  • XCode
  • Hammer4Mac

XCode 10.1 falls over if I try to start it. It says that it requires additional components and then fails to install them. I may upgrade XCode at some point. But I only use the compiler from the command line via QtCreator, so it doesn’t really matter at present.

Hammer4Mac is a static website builder I use to build the PerfectTablePlan website and a couple of other mini sites. I upgraded to the latest version. It starts, but returns ‘Build failed’ for all 3 websites. No clue as to why. I Tweeted the creator, but got no reply. It appears to be abandonware. If so they should really take down the Hammer4Mac website. I guess I will use it from my macOS 10.14 laptop and then eventually do the tedious job of porting those websites to Jekyll.

Hopefully I won’t have to do another major upgrade of macOS any time soon (I may buy a new Mac next time).

Easy Data Transform v1.0.0 released


I finally released a paid version of Easy Data Transform today, for both Windows and Mac. I am very pleased with how it has turned out. Obviously it is only v1.0.0, so there is plenty of additional features I could add, including:

  • Batch processing
  • Support for JSON, XML, SQLite input/output
  • More transforms
  • A 64 bit version for Windows
  • A Linux version

But I need to listen carefully to prospective customers to decide which additional features to prioritize in future releases. It might be something I haven’t even thought of.

But v1.0.0 already has a really useful core of features. And, if you aren’t embarrassed by v1.0, you didn’t release it early enough. That said, I haven’t cut corners on quality. It has proper documentation and has been through extended beta testing, dogfooding and several rounds of usability and third party testing.

The product has a fully-functional 7 (non-consecutive) day free trial. I think that is enough for prospective customers to decide if it does what they need. I also have a 60 day money-back guarantee.

I have decided to go with a subscription model: $99 / €90 / £75 + tax per person per year. Which covers up to 3 computers. At this price point I can afford some paid promotion and to provide a decent level of support. I am not offering a monthly subscription, as I don’t really want people who are going to pay for 1 month (to do their annual TPS reports) and then cancel.

Have you got some data you need to merge, clean, reformat or de-dupe? Give it a try. You can get a 25% discount if you buy a subscription by the 27th December 2019 using this link.


Easy Data Transform

I have been furiously coding a new product. Easy Data Transform. It is a Windows and Mac tool for transforming table and list data from one form to another. Joining, splitting, reformatting, filtering, sorting etc.


I have been thinking about this product idea for years. In fact I threw together a janky prototype back in 2008. It allows you to perform various operations on a pair of lists.


I used this prototype for jobs such as creating a list of emails of people who had bought Perfect Table Plan v5, but hadn’t upgraded to v6 yet. It worked. But it wasn’t very good. The biggest annoyance was that each operation obliterated everything that came before. Which made it very easy to lose track of where you had got to. And there was no repeatability. It was also limited to lists and it became clear that I really needed something that could also handle tabular data. I never released it.

But the idea has been running as a background process in my brain for 11 years since. And I think I have come up with a much better design in that time. Finally I had mature, stable versions of my Perfect Table Plan and Hyper Plan products out, so I decided to go for it. I am really pleased with how it has turned out so far.

If you aren’t embarrassed by v1.0 you didn’t release it early enough. And so I have cut lots of corners to get this first public version out. The documentation is only part written. I created the application icon myself  in 10 minutes. There is no licensing. The GUI is lacking polish. The website would make a designer cry. But the software seems fairly robust. My 13 year old son wasn’t able to crash it after 10 minutes of trying, despite financial incentives to do so.

I did some market research and spoke to some people who knew a bit about this market. But I deliberately didn’t look closely at any competing products, as I didn’t want to be mentally restricted by what others have done. For better or worse, I want to blaze my own trail. Copying other people’s stuff is a zero-sum game with no net benefit to society.

Most of the things that Easy Data Transform you can do, you can also do in Excel or SQL. My claim is that it is much quicker, easier and less error prone to do in Easy Data Transform. No programming or scripting required. I am hoping that people will be able to start using it within a couple of minutes of downloading it (I plan to do lots of usability testing). Will people pay for that? I hope so. I’m not aiming it at programmers. Perish the thought.

Naming is hard. I came up with some 70 names. Things like ‘Data Hero’, ‘Transform Flow’, ‘Transmogrify’ and ‘Data Rapture’. But the domains were taken, people I asked hated them or there was an existing service or product with that name. So I ended up with Easy Data Transform. It does what it says on the tin.

Why desktop? Surely no-one is writing new desktop apps in 2019? I believe a desktop solution has some real advantages in this market. The biggest ones are:

  • You don’t need to load your (potentially highly sensitive) data on to a third party server.
  • Not having to upload and download (potentially very large) data sets makes it much more responsive.

Easy Data Transform is currently free for anyone to use. You can get it from the super-minimalist website. The current 0.9.0 version expires on the 4th August 2019. You will then be able to get another free version. Once the product is mature enough, and if I am convinced there is enough demand, I will release a paid version. The free beta will probably last several months. Please try it and let me know how you get on. I am particularly interested to get feedback from anyone using it for real day-to-day tasks.

Of course the real challenge is always marketing. How to get noticed amongst many competing products. As well as helping to improve the product I am hoping that this extended beta will also help me to get some traction and better understand the market. For example, what price to charge and what trial model to use. Watch this space.


I wondered what it would look like if you took a body of text and then used it to generate new text, using Markov chains of different lengths. So I knocked up  quick program to try it.  ‘Bloviate’.


Bloviate analyses your source text to find every sequence of N characters and then works out the frequency of characters that come next.

For example, if you set N=3 and your source text contains the following character sequences staring with ‘the’:

‘the ‘, ‘then’, ‘they’, ‘the ‘

Then ‘the’ should be followed 50% of the time by a space, 25% of the time by an ‘n’ and 25% of the time by a ‘y’.

Bloviate then creates output text, starting with the first N characters of the source text and filling in the rest randomly using the same sequence frequencies as the source text.

Note that a character is a character to Bloviate. It treats upper and lower case as different characters, makes no attempt to differentiate between letters, punctuation and white space and does not attempt to clean up the source text. Which also means it works on any language.

Bloviate also tells you the average number of different characters following each unique sequence of N, which I will call F here. As F approaches 1.0 the output text becomes closer and closer to the input text.

Using ‘Goldilocks and the 3 bears’ as input:

If N=1 (F=7.05) the output is garbage. Albeit garbage with the same character pair frequency as the original.

On cre She sl s ramy raked cheais Bus ore than s sherd up m. ged. bend staireomest p!”Sof ckstirigrorr a ry ps.

” f waine tind s aso Sowa t antthee aime bupis stht stooomed pie k is beche p!

At N=3 (F=1.44) it looks close to English, but jibberish:

Once up and been sight,” she this timed. Pretty so soon, she second soft. She screame up and she screame hot!” cried the Mama bed the Papa been sleeping in the Papa bear

“Someone’s bear growl.

At N=5 (F=1.14) it starts to look like proper English, but semantically weird:

Once upon a time, so she went for a walked right,” she lay down into the kitchen, Goldilocks sat in the porridge from the three chair,” growled, “Someone’s been sitting my porridge and she tasted the door, and ran down the bedroom. Goldilocks woke up and she second bowl.

And it comes out with occasional gems such as:

“Someone’s been sitting my porridge,” said the bedroom.

At N=10 (F=1.03) it starts to become reasonably coherent:

Once upon a time, there was a little tired. So, she walked into the forest. Pretty soon, she came upon a house. She knocked and, when no one answered, she walked right in.

At the table in the kitchen, there were three bowls of porridge.

At N=15 (F=1.01) it starts to get pretty close to the original text, but doesn’t follow quite the same order:

Once upon a time, there was a little girl named Goldilocks. She went for a walk in the forest. Pretty soon, she came upon a house. She knocked and, when no one answered, she walked right in.

At the table in the kitchen, there were three bowls of porridge. Goldilocks was very tired by this time, so she went upstairs to the bedroom. She lay down in the first bed, but it was too hard. Then she lay down in the third bed and it was just right. Goldilocks fell asleep.

At N=12 (F=1.07) the whole 680k characters of ‘Pride and prejudice’ produces:

It is a truth universally contradict it. Besides, there was a motive within her of goodwill which could not help saying:

“Oh, that my dear mother had more command over herself! She can have her own way.”

As she spoke she observed him looking at her earnest desire for their folly or their vice. He was fond of them.”

Obviously the source text is important. The Bohemian Rhapsody lyrics make nearly as much (or as little sense) at N=5 (F=1.08) as the original:

Is this to me, for me, to me

Mama, just a poor boy from this to me

Any way the truth

Mama, life? Is this time tomorrow

Carry on as if nothing all behind and face the truth

Mama, ooh, didn’t mean to me, baby!

Just gotta leave me and lightning, very fright out, just killed a man

Put a gun against his head

Pulled my time to die?

At N=12 (F=1.05) 160k characters of Trump election speeches produces:

Hillary brought death and disaster to Iraq, Syria and Libya, she empowered Iran, and she unleashed ISIS. Now she wants to raise your taxes very substantially. Highest taxed nation in the world is a tenant of mine in Manhattan, so many great people. These are people that have been stolen, stolen by either very stupid politicians ask me the question, how are you going to get rid of all the emails?” “Yes, ma’am, they’re gonna stay in this country blind. My contract with the American voter begins with a plan to end government that will not protect its people is a government corruption at the State Department of Justice is trying as hard as they can to protect religious liberty;

Supply your own joke.

I knocked together Bloviate in C++/Qt in a couple of hours, so it is far from commercial quality. But it is fairly robust, runs on Windows and Mac and can rewrite the whole of ‘Pride and prejudice’ in a few seconds. The core of Bloviate is just a map of the frequency of characters mapped to the character sequence they follow:

QMap< QString, QMap< QChar, int > >

You can get the Windows binaries here (~8MB, should work from Windows 7 onwards).

You can get the Mac binaries here (~11MB, should work from macOS 10.12 onwards).

Note that the Bloviate executable is tiny compared to the Qt library files. I could have tried to reduce the size of the downloads, but I didn’t.

To use Bloviate just:

  1. paste your source text in the left pane
  2. set the sequence length
  3. press the ‘Go >’ button

I included some source text files in the downloads.

You can get the source for Bloviate here (~1MB).

It should build on Qt 4 or 5 and is licensed as creative commons. If you modify it, just give me an attribution and send me a link to anything interesting you come up with.

How to notarize your software on macOS

** Please note: WordPress keeps mangling my code examples by changing double dash to single dash. I tried to fix it. But it changed them all back again! If anyone knows how to get around this, please put something in the comments. **

Apple now wants you to ‘notarize’ your software. This is a process where you upload your software to Apple’s server so it can be scanned and certified malware free. This will probably become compulsory at some point, even (especially?) if your software isn’t in the Apple app store. Apple says:

Give users even more confidence in your software by submitting it to Apple to be notarized. The service automatically scans your Developer ID-signed software and performs security checks. When it’s ready to export for distribution, a ticket is attached to your software to let Gatekeeper know it’s been notarized.

When users on macOS Mojave first open a notarized app, installer package, or disk image, they’ll see a more streamlined Gatekeeper dialog and have confidence that it is not known malware.

Note that in an upcoming release of macOS, Gatekeeper will require Developer ID signed software to be notarized by Apple.

Documentation on notarization is a bit thin on the ground, especially if you want to notarize software that wasn’t built using XCode (I build my software using QtCreator). So I am writing up my experiences here.

First you need to ensure you have macOS 10.14 and XCode 10 installed (with command line tools) and you need a current Apple developer account.

Codesign your app with ‘hardened runtime’ using –options runtime :

codesign –deep –force –verify –verbose –sign “Developer ID Application:<developer id>” –options runtime <app file>


codesign –deep –force –verify –verbose –sign “Developer ID Application: Acme Ltd” –options runtime

A ‘hardened runtime’ limits the data and resourced an application can access. I’m not sure what the exact ramification of this are. But it doesn’t seem to have restrict my software from doing anything it could do previously.

You can check the signing with:

codesign –verify –verbose=4 <app file>


codesign –verify –verbose=4

Now package your app into a .dmg (e.g. using DropDMG). Then upload the .dmg to Apple’s servers:

xcrun altool -t osx -f <dmg file> –primary-bundle-id <bundle id> –notarize-app –username <username>


xcrun altool -t osx -f myApp.dmg –primary-bundle-id com.acme.myapp –notarize-app –username

You will be prompted for your Apple developer password (or you can include it on the command line).

You now have to wait a few minutes. If the upload is successful “No errors uploading ” will be shown and a unique ID will be returned. You then have to use this to request your upload be scanned:

xcrun altool –notarization-info <notarize ID> -u <username>


xcrun altool –notarization-info xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx -u

You will be prompted for your Apple developer password (or you can include it on the command line).

Hopefully you will see “Status Message: Package Approved”. If the notarization fails, you should be sent a link to an online log file describing the issue. If the notarization completes successfully you need to ‘staple’ the results to your .dmg:

xcrun stapler staple -v <dmg file>


xcrun stapler staple -v myApp.dmg

The stapler outputs a log including some odd phrases. Mine included: “Humanity must endure”, “Let’s see how that works out. “, “Adding 1 blobs to superblob. What about Blob?” and “Enjoy”. Weird. Hopefully it will end with “The staple and validate action worked!”.

Finally you can unpack your .dmg into a .app and verify it with:

spctl -a -v <app file>


spctl -a -v /Applications/

On macOS 10.14 (but not earlier OSs) it should say “source=Notarized Developer ID”. Your software should now run on 10.14 without a warning dialog. Congratulations!

It all seems rather clumsy. As you have to wait asynchronously for the unique ID to be returned from step 1 before you can complete step 2, it is not easy to fully automate in a script. This is a major pain the arse. If anyone works out a way to automate it the whole process, please let me know.

Here are some links to the various posts that I gleaned this information from:

Qt is broken on macOS right now

Let me say up front that I am a big fan of the Qt framework. I have been working with it continuously since the late 90s. Both of my commercial products (PerfectTablePlan and Hyper Plan) are written on top of Qt. But Qt is quite broken on macOS right now. In fact I struggled to find a version of Qt 5 that supported recent versions of macOS and didn’t have a showstopper bug. I must have wasted a couple of weeks grappling with these issues. I am putting my notes here in the hope that they help someone else.

Here are the 4 bugs in macOS version of Qt that have causing me the most headaches:

Qt Version
bug v5.9.6 v5.10.1 v5.11.0 v5.11.1 v5.11.2
QFontDialog broken (link) ok ok ok ss ss
QStaticText::size() returns wrong value for rich text
with line breaks
ss ss ok ok ok
widgets such as QTableWidget do not repaint correctly (link) ok cwa cwa cwa cwa
default QComboBox size is incorrect (link)
ok ok cwa ok ok


ok = bug not present.

cwa = bug present, but can workaround.

ss= bug present, making release unusable for me (showstopper).

Consequently Qt 5.11.0 is the only usable release on macOS for me and I have to kludge my way around two quite nasty bugs. While the QStaticText issue is fairly obscure (but important for me), how in the hell did QFontDialog get completely broken without anyone noticing? And then not get fixed for two whole releases?! I also know other developers who are having to stick with earlier versions of Qt due to the bugginess of the recent versions of Qt on macOS. This isn’t good enough.

Thankfully the recent versions of Qt are much more solid on Windows.

** Feb-2019 Update: Qt 5.12.0 seems to be a big improvement. **

** Mar-2019 Update: I had to revert PerfectTablePlan to Qt 5.11.0 because versions built with 5.12.0 and 5.12.1 kept crashing deep in Qt. **

** Sep-2019 Update: I had to revert PerfectTablePlan to Qt 5.11.0  again because versions built with 5.12.4 kept crashing deep in Qt. **

** Oct-2019 Update: Qt 5.12.5 fixes all the bugs above and doesn’t seem to introduce any major new bugs that I care about. **

Getting Qt 5.9 working on Windows (eventually)

I have had Qt 5.5 and 5.6 installed on my development machines for some time. Now that I have purchased a new Mac development box (an iMac with a lickably beautiful 27″ screen) I thought it was a good time to update to a more recent version of Qt. I went for Qt 5.9, rather than Qt 5.10, as 5.9 has been designated as an LTS (long term support) release. Upgrading turned into a real chore. I am quickly writing it up here in the hope that it helps someone else, and as a reminder to myself a few years down the line.

I like to build Qt from source. Because then I know it was built using the same compiler, headers, SDK etc as I am using to build my product. And I have more control over how Qt is configured. Also I can patch the source and rebuild it, if I need to. But I have had problems building Qt on Mac before. So I decided to install the pre-built binaries on my new Mac. I installed the latest version of XCode and then the Q5.9.4 binaries. This was a couple of big downloads, but it all went pretty smoothly.

I successfully built Qt 5.5 from source on my Windows machine previously, so I decided to try that for Qt 5.9. I have Visual Studio 2010 installed. This isn’t supported for Qt 5.9.4, so I downloaded Visual Studio 2017. I unzipped the Qt source into C:\Qt\5.9.4, ran ‘x86 native tools command prompt for VS 2017’, made sure Python and Perl were in the path and then:

cd C:\Qt\5.9.4

set QTDIR=C:\Qt\5.9.4\qtbase

set PATH=%QTDIR%\bin;%PATH%

configure -opensource -confirm-license -opengl desktop -nomake tests -nomake examples -no-plugin-manifests -debug-and-release -platform win32-msvc -verbose


Note that you are told by the nmake script to do nmake install at the end of this. But it tells you somewhere in the Qt Windows documentation not to do this, unless you have set the prefix argument (confusing, I know)

The build failed part way through making qtwebengine. Something to do with a path being too long for Perl or Python (I forget). It seems to be a known problem. Odd as the root path was just C:\Qt\5.9.4. I don’t need qtwebengine at present, so I deleted everything and tried again with -skip qtwebengine:

configure -opensource -confirm-license -opengl desktop -skip qtwebengine -nomake tests -nomake examples -no-plugin-manifests -debug-and-release -platform win32-msvc -verbose


It seemed to complete ok this time. But using this version of Qt to build Hyper Plan I got an error:

Unknown module(s) in QT:svg

On further examination the SVG DLL  had been built, but hadn’t been copied to the C:\Qt\5.9.4\qtbase\bin folder. Similarly for a lot of the other Qt DLLs. I couldn’t find any obvious reason for this looking through logs, Stackoverflow and Googling. I could possibly do without the SVG functionality, but I wasn’t sure what else was broken. So I decided to give up on bulding from source on Windows as well.

I download the Qt 5.9.4 binaries for Visual Studio 2017. This seemed to go ok, but then I discovered that I could only build a 64-bit application from these. No 32-bit version was available for Visual Studio 2017. Many of my customers are still on 32 bit versions of Windows. So I need to be able to ship my product as a 32 bit executable + DLLs[1].

So I uninstalled Visual Studio 2017 and installed Visual Studio 2015. I then got an error message about Visual Studio 2017 redistributables that I hadn’t uninstalled. So I had to uninstall those and run a repair install on Visual Studio 2015. That seemed to work ok. So then I download the 32-bit Qt 5.9.4 binaries for Visual Studio 2015. I had to download these into a different top level folder (C:\Qtb), so as not to risk wiping existing Qt installs that I had previously managed to build from source.

Eventually I managed to build Hyper Plan and PerfectTablePlan on Mac and Windows. What a palaver though! Qt is an amazing framework and I am very grateful for everyone who works on it. But I wish they would make it a bit easier to install and upgrade! Has anyone actually managed to get Qt 5.9 built from source on Windows?

[1] I don’t bother shipping a 64-bit executable on Windows as the 32-bit executable works fine on 64-bit versions of Windows (my software doesn’t require excessive amounts of memory). I only ship a 64-bit executable on macOS as almost no-one uses 32-bit versions of macOS now.

Bundlefox review

I have been using bundles and 1-day sales as a useful way to increase the exposure for my visual planning software. I have had positive experiences with BitsDuJour, Macupdate and BundleHunt. Once you put your software in one bundle you inevitably get approached by people who run other bundle promotions. I was approached by Bundlefox and agreed to put Hyper Plan in their Mac software bundle. I wish I hadn’t. It has been a pretty miserable experience from start to finish. In brief:

  • I never knew when the promotion was going to start or end. I was told it was going to start on 27th February, but it eventually started on 20th April. It was supposed to run for 3 weeks, but actually ran for 6 weeks. This is a problem, because it means you can’t put your software in other sale or bundle that require an exclusive discount.
  • Communication was poor. They generally took several days to reply to emails.
  • The number of licenses sold was very low, especially compared with sales of Hyper Plan on BundleHunt.
  • Worst of all, they only paid me 60% of what I was expecting per license. When I queried this they emailed me back “It’s **% revenue share after fees, most of the sales came in through affiliates and we had to pay them off before sharing the revenue”. I went back through their emails and their ‘Vendor Manual’ and there is no mention of affiliate fees being subtracted. It just says “You would receive a percentage of the total payments received for the bundle minus PayPal fees”. In fact I had emailed them “So if you sell 2000 bundles for $12 of which 500 choose Hyper Plan, I get **% of $12×500 = $***?” and they replied “Your calculation is correct”. I feel deceived.
  • The low number of licenses sold and the low payout per license means that it wasn’t worth the effort to setup.

I don’t know what Bundlefox are like to deal with as buyer, but I recommend vendors give them a wide berth.
