So I have a lot of older Adobe software on my home computer (CS6.) It’s just there because that computer is that old.
I recently updated to Mojave and just did the latest update.
Not sure why I haven’t been seeing these before because the “feature” was supposedly present in Yosemite, but now my Mac is telling me on every startup that one piece of software is “Not Optimized” for the current version of Mac OS and needs to be updated. It’s always a different piece and it’s always old Adobe gear.
Apparently Apple is phasing out 32-bit support in favor of 64 only. Its been going on a few years now but looks like time is up.
Old Adobe apps supposedly will still run, but with glitches. Their days are numbered.
Soon you will all be assimilated.
