Yesterday one of our internal media drives got locked up so we no longer had read or write access even from the Admin account of our Mac Pro.
As a result, the easy Get Info permissions fix was not an option.
So, I dove into the Terminal to make some repairs. A simple chmod command didn’t work either, but here’s what did:
- Open a new Terminal window
Located in ./Applications/Utilities - Enter the following into the Terminal
sudo chflags nouchg /Volumes/<drive name here>- If there are spaces in the name you will need to put double quotes around it like so:
/Volumes/”<drive name here>”
- If there are spaces in the name you will need to put double quotes around it like so:
- Change permissions
sudo chmod 775 /Volumes/<drive name here>
Hope that helps. Permissions problems can be a real pain.
