I am also sitting still on Mojave. In the past there were usually compelling reasons to upgrade - in terms of quality of life and performance. Catalina, in my use cases, doesn't really do a whole lot for me. I can't think of a single feature that I want aside from perhaps the standalone Podcasts app. But because of all the noise raised during the last upgrade season from Mojave to Catalina I decided that the juice definitely wasn't gonna be worth the squeeze.
So now I have pretty much decided to just cruise this 2018 MBP along on Mojave until I replace the machine entirely. If it ain't broke, don't fix it.
- software for a "smart pen" where the company went out of business
- some label printing software
- some Steam games
- some games from GOG
Even if I don't run these daily, I don't like to be cut off from my past.
Still get a regular trickle of emails from schools complaining about it. I tell them to call Cupertino.
It also did not break OpenGL, only deprecate it. macOS is still stuck on a many-years-old version of OpenGL, but what worked in the past continues to work. Even Apple Silicon Macs will support it.
Mojave on my 13” MBP 2015 is still fantastic. Great OS, great keyboard, USB ports, MagSafe, etc.
My money's on "Sequoia".
Next up has got to be "Bigger Sur", then "Biggest Sur" is up after, and then they'll finally be done.
