The problem is that the folder ~/Library/Application\ Support/Propellerhead\ Software has either the wrong ownership, the wrong permissions, or both. In my case it had become owned by root:wheel and the permissions prevented Authorizer from entering the folders beneath. I don't know what happened on my system as I certainly didn't knowingly change them.
Anyway...
Open Terminal and enter these commands substituting your actual username where you see your_username below.
Code: Select all
cd ~/Library/Application\ Support
sudo chown -R your_username:staff Propellerhead\ Software
sudo find Propellerhead\ Software/ -type d -exec chmod 750 {} +
sudo find Propellerhead\ Software/ -type f -exec chmod 640 {} +
750 is read/write/execute for owner (your_username), read/execute for group (staff), and no access for everyone
640 is read/write/ for owner (your_username), read for group (staff), and no access for everyone
