As a subscriber to Adobe Creative Cloud, I’ve recently run into an issue with the Creative Cloud app where it would not remember from moment to moment that I had signed in. Credentials would not save and while it would connect long enough to get me into say, Photoshop, launching something else like Illustrator would cause the Adobe Application Manager to prompt for a sign in. When I would confirm the sign in, it would just hang. After some Googling, I came across this page:
For Mac OS, the article recommends closing all things Adobe (I had to “Force Quite” the Adobe Application Manager), then browse to ‘~/Library/Application Support/Adobe/OOBE/’. Delete the ‘opm.db’ file and you’re good to go. Next time you login, the file will re-generate and you should be good to go. I’m blaming corruption possibly triggered when the card on file for payment lapsed.
Anyways, all is well again. Hope this helps someone!
