If you use Adobe Photoshop on a Mac with OS X (appears to be Yosemite or newer), you may have run into the error “Could not complete your request because of a program error”. Unfortunately, this error isn’t very descriptive about the actual issue. After browsing a few sites about this error, it appears to be related to file permissions. If you don’t mind setting up a new user, one easy fix is to create a new admin user and use that account for Photoshop.
– Using the Finder app, Hold down the Alt (Option) key when using the Go menu. The user library folder is listed below the current user’s home directory.
Note: After you open the Library folder, you can drag the Library icon from the top of that window to the Dock, Side Bar, or toolbar. That way, it’s readily accessible.
– You’ll want to find the folder: /Users/USERNAME/Library/Application Support/Adobe – Unlock the folder – Apply Read Only to this and all inside folders for ‘staff’ and ‘everyone’ – Apply Read & Write for your username
