TIPS
What are disk permissions?
All the files on your Mac Pro have
permissions
associated with them. Permissions are a
collection of settings that determines what users or groups of users can do with each file.
For example, if read-only permissions apply to a file, it means that all users can only read
the contents of the file and cannot make any changes to the file or delete it. If the permis-
sions for your Mac Pro's system files change or get corrupted, it can cause problems, in-
cluding program lock-ups and unstable system behavior.
