I had a permissions error with my Apple Mail last night. Specifically, I was receiving the following below error: “Mail can’t open because you don’t have the necessary permissions to change the folder where it saves information.”
I’ll detail what I tried to do to fix this problem, and what actually worked.
Repairing Permissions, Part One
First, I opened the Disk Utility, clicked on my Macintosh HD, and Repair Disk Permissions. While this successfully fixed a previously unknown CUPS permission issue, it didn’t do anything to fix my Apple Mail woes.
