It took me some time to get PSE 2020 installed on macOS Tahoe: cleaning with the downloaded Creative Cloud Clean up tool after migration and then only a new download of the dmg package from my product page in my Adobe Account worked. Then Organizer started as expected, but when choosing the Editor an error message comes up immediately, stating that at least macOS X is required. Obviously Tahoe macOS 26 is fitting to that requirement. I hope PSE is not just looking for a macOS pre-number 10???
I hope someone can help please?
