I’m currently using Mojave. Anyone have problems with PS after upgrading to Catalina and/or Big Sur? Should I upgrade?

I totally agree Birddog. I’ve been using Macs since 1986 and follow the same advice. You must also check websites of software you use. I always do a web search as well to see if anyone has reported major issues.Ditto with Gordon. No problems whatsoever. I always, though, wait at least two or three months before installing a major new release of the Mac OS. This gives Apple time to smooth out all the inevitable bugs found in a new release, and allows software developers to do the same. I got my first Mac in 1985, and this philosophy has saved me countless hours and much aggravation over the years. You don't want to fall too far behind in OS releases, but I'm not interested in being a beta tester, either, when I have work to get done. Catalina has been around long enough to be completely stable and reliable.
After doing what Birddog suggest and you find that there is no 64 version, Another option would be to have a second startup disk and retain Mojave on that one . If there is an app that you love and there is no 64 bit update to it run the 32 bit app on the Mojave Drive.I should have mentioned one very important issue: Mojave was the last Mac OS that will run 32-bit applications. Catalina will not. If you depend upon any old 32-bit software, be sure to research 64-bit upgrades or substitutes, because the old ones won't work. I used a simple free app called Go64 (https://www.stclairsoft.com/Go64/) that identifies any 32-bit apps on your machine. This Apple support article (https://support.apple.com/en-us/HT208436) also describes how to identify legacy apps.
Or you could get virtualization software like 'Parallels' or 'VMFusion' and install Mojave on it. That way, you can run both Mojave and Catalina/Big Sur without neeing to re-boot your computer.After doing what Birddog suggest and you find that there is no 64 version, Another option would be to have a second startup disk and retain Mojave on that one .

Looks like your last sentence 'got away from you'One other thing think about for Mac users is that Lightroom 6 perpetual licence will not run on IOSCatalina, unless you have installed LR6 on Mojave or earlier and before tour system upgrades to Catalina upgrade because of the lack of 32 bit support in Catalina. This forces you to take the monthly or annual creative cloud subscription for Lightroom Classic etc. PS 2020 runs fine as airy if the CReative cloud pack
Mac OS makes it incredibly easy to have multiple boot up drives.Something that the Mac OS makes incredibly easy is to have a second drive setup as a backup boot drive and boot from it if there are any problems. When I had a Mac workstation I would back up the primary boot drive to the secondary drive and then boot from the second drive to verify everthing was OK. If updates to the primary boot drive created a problem then I could boot off the second drive and not lose any time. I could then backup the second drive to the first to restore the state of the primaty drive.
