Being a Windows PC user, I have been using PSE for many years. Currently running PS Elements 12 with Windows 11. Yeah its old - but no problems…
However… a friend has an iMac (late 2015) with a 3.3 GHzQuad-Core Intel Core i5, now updated to Monterey 12.7.3. I am trying to work out what version of PSE would suit it & work OK.
I use Photoshop elements on my Mac. Until about a month ago it was running problem free on Monterey, now upgraded to Sonoma and not had any problems. In fact no problems with any software except I run Weathercat and had problems downloading the Silabs USB drivers drivers, but even that is fine now.
