Fixing Apple Mail

200810241645I 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.

Repairing Permissions, Part Two

On my second attempt, I tried to reset the Access Control Lists (ACLs) and permissions for the home directory. This involved the following:

  1. Boot to the OS X install CD;
  2. Select ‘English’ (my native language);
  3. Click Utilities, the user for whom I wanted to reset the settings, and then reset their settings;
  4. Quit the program and boot to OS X;
  5. Open Macintosh HD from Finder, double click the Users folder, and click one on the User I was having permissions problems with;
  6. Right-click on that User, and select Get Info;
  7. In the Sharing and Permissions area unlock the lock, and click on the gear-like icon. Select Apply to Enclosed.

This did not resolve my problem.

The Solution: Time Machine and Capsule

To resolve my problem, I had to first delete the Mail directory in Macintosh HD:Users:<User>:Library before I could restore a backup from my Time Capsule using Time Machine. Just trying to restore the old Mail folder gave me an error that I didn’t have permissions to modify the contents of the Mail directory; this error message vanished once I actually deleted the Mail folder itself. This did resolve my problem.

    apple mail today reset itself…I click on MAIL in the dock and it gives me the original setup window. I ran disk utility and it did not correct the problem. I am wondering if i simply trash the old mail directory if I can re-open mail WITHOUT resetting everything. Any help greatly appreciated.

    @ Aaron – this was first posted October 2008.

    @ Kevin – if you are using time machine, I’d try just restoring the whole mail directory (assuming that you want to try and undo mail’s resetting of itself)

    This happened to a coworker, and I just couldn’t get myself to restore from backup since it has to be a permissions snag. A little searching later, I found the solution in the Apple discussion forum:

    The solution was to use BatChmod, a tool that fixes permissions, including ACL.

    Here’s the settings I used:

      Thanks for that bit of legwork – I’d tried working through permissions, and didn’t find anything at the time of the problem, so the capsule was the solution for me. Good to know the ‘more right’ way! 😛

    That was awesome. It did the trick without resorting to a TC restore. Thanks for the tip!

    Worked for me too thanks ! I read somewhere this was caused by TC itself. It’s the first time I use my TC backup … and it would be for a folder corrupted by TC !

    Glad that this helped you solve your problem! 😀
