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 com.apple.dt.Xcode 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/XCode.app/Developer/usr/bin 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).

    A few notes from a fellow (Windows) software developer:
    – Always use virtual machines to develop so that you could simply spawn a new machines and upgrade your guest or host OS independently
    – Instead of Jekyll, you should consider Hugo which is a lot faster and powerful

      It has some useful features and works on both Windows and Mac. Also it is what all the screen captures for my documentation have been done with and I want to keep a consistent look.
