Hey, I'm wondering whether or not it would be beneficial to change the file permissions on the /Library folder and its contents to: system: Read & Write admin: Read-only everyone: Read-only In theory, this would provide better security, since modifying all users' /Library folder would require administrative rights (one would have to type the password to modify anything), correct? If I am correct, and if this is a good idea: is there any way to get Onyx's or Disk Utility's permission corrector to skip over the /Library folder? I have actually changed the permissions on my /Library folder just to see what would happen. Consequently, Time Machine went out and backed up 1.4GB of stuff. I didn't notice it at first, but I noticed it was backing up 1.4GB (apparently the second time) when I used Onyx to verify and fix file permissions. Any advice is appreciated. Thanks.
