Apple is pretty bad. They nuked all 32-bit support at some point, which made almost my entire Steam library unplayable until I cobbled together a Windows box. When coupled with the idiotic UI design direction they have taken the last 10 years, MacOS is no longer a contender for me.
The 32 bit support nuking was in fact the source of my macOS concerns too, and why I was looking over the fence to see if Windows offered me some shelter from the tech treadmill.
Current plan is to see if I can run 10.14 in a VM for 32 bit apps and finally ditch the hardware I’m keeping for them.
