It occurred to me this morning that I don’t have any pressing need to upgrade to macOS Catalina, with the upheaval that would entail. My current setup with Mojave is working just fine, and just about all of my most-used apps are ready for Catalina.
A few things won’t work when I do upgrade. My old printer definitely won’t work, but that is approaching the end of its useful life after over a decade of service, so I’ll look to replace that with an AirPrint-compatible model in the New Year.
The other sticking point has been games, primarily those in my Steam library. Most of those will stop working on Catalina, but then again, many more of the Steam games I own won’t run on Mac at all, period. I’ve looked into running them through the copy of Windows 10 that I’ve got installed using Parallels Desktop, but so far it has been hit-or-miss whether they work. I’m seriously considering trying to get them running on Linux, as it appears that compatibility is greatly improved nowadays.
