I have a big problem : I can't save nor reopen any after effects file. It always say that it is impossible to replace the Adobe After Effects 12.2 prefs.txt.
I've tried to delete the prefs.txt file, tried to delete the entire 12.2 folder, tried to repair permissions but nothing happened !...
I'm on Mac OS 10.9.3 and After Effects 220.127.116.11. It seems to have happened since the last update.
Thanks for your help.
Set the permissions for the entire preferences folder to read/write, not read-only. (This is not the same thing as "repairing permissions".)
Ok, thanks, but your article isn't speaking about how to do that exactly.
So after some researches, what worked for me is to set "read and write" permissions to Everyone and to apply it to all subfolders thanks to the little cogwheel at the bottom of the Mac Info window.
