I just suffered through an automatic update on MacOS to Catalina - this has been the most painful, idiotic thing to happen in my studio in a long time, and I now feel about Apple the way I did about Microsoft last century, when I abandoned them .. just utterly disappointed, and more the point I feel exploited just so that Apple can update its OS and force us to move onto their next big thing.
More and more, I'll replace the Mac with an Ubuntu Studio-oriented DAW, and then I'll phase out using Macs entirely. Linux is catching up in a big way, especially for use as Audio/Media workstation. Its not 100%, but its certainly better than having arbitrary decisions forced on me by the OS masters in Cuppertino.
(And yes, I've disabled auto-update. Shouldn't have been on in the first place, on this production system...)
