I have always been a Mac user. Currently using a 2013 Mac pro with 32 ram and OS 10.14.6. Before that, for 8 years I used a Mac Tower that was reasonably well fitted out. My desktop is used for LR and Photoshop and little else. I have always kept up to date with OS upgrades (except the current Catalina). Photoshop and LR are on my boot drive, and my photos live on a spinning external drive connected by USB 3. I have checked my hardrives frequently for problems and never have found any. With my old grey desktop, I noticed that over the years Photoshop became increasing fussy, and I had to reset Photoshop preferences often, in the last year about once a month. The same thing is happening now with my 2013 Mac Pro. For the last year I have had to reset preferences about once a month, and currently it is unusable because of some sort of problem (the subject of another post here) that I cannot explain or fix, in spite of uninstalling and reinstalling it multiple times. I have had to create another user and it seems to work OK for now. So, I have questions. What is causing PS to become buggy with age? Is it aging hard drive problems that don't show up with testing? Is it the upgrades in Adobe and Apple that are creating the problem, ie, a software issue between two complicated programs that just become increasing pronounced with age? Is it inscrutable hidden corrupted files that don't disapper with uninstalling and reinstalling? And, I would like to know if PC users have had the same problem, Photoshop becoming buggy after a few years and well equipped hardware. It is only a matter of time that my 2013 Mac will not be compatible with the latest Mac OS upgrade and I will need to replace my computer. I am seriously considering jumping ship to a PC, for all of the well described deficiencies in Apple desktops: lack of much of a choice, inability to upgrade components, and cost. Is there any consensus out there regarding ease of use of Photoshop on aging PCs verses Macs?
