Home Forums Peripherals & Multimedia Audio, Video, Photography Photoshop crashing

I don't know why Photoshop is crashing on my iMac, both the start up drive and the backup drive. However it does work on my MacBook Air (latest Mojave) and my Mac Pro (High Sierra).

Trouble is, the MacBook Air version is 12.0.0 installed from the original dvd. I have tried the back dating trick to get the official updater to work, but no luck.

Today, I simply copied all the PS folders I could find from my Mac Pro to my MacBook Air. It worked. Thing is, Photoshop won't open a native Affinity Photo file (.afphoto) which seems to be the equivalent of .psd

Affinity Photo will open a .psd file. I am liking AP. Also, I can replace Bridge with Graphic Converter, which offers a slide show and good browser. I'm almost ready to upgrade to Catalina, I think...
