I followed Aunin’s instructions with some minor modifications:
- Go to Terminal
- Type ‘crontab -e’
- The Crontab will open. Press ‘i’ to insert a new line.
- Copy and paste ‘*/1 * * * * chmod 777 /Applications/World\ of\ Warcraft/.build.info’ (not including the quotes) onto the first line
- Press ‘esc’ (Escape)
- Press ‘:’ (colon)
- type ‘wq’ to save the Crontab
This will run a script in the background every 1 minute that resets the permissions on the ‘.build.info’ file from 666 (read-write) to 777 (read-write-execute). The reason you want to use the Cron is because every time you install a Battle.net update, or install a new add-on, the permissions get reset to 666, which is the issue.
