How to: Repair Permissions via Disk Utility in Mac OS X

DiskUtilityIconBecause OS X sits on another operating system called Unix, it handles files differently then a Windows computer.  This is because each file on that computer has what we call Permissions.  Permissions tell Unix what it can do with the file - if it can read it, or write data to it, etc.

But sometimes (for what ever reason) those permissions get changed around.  So, let's say that a data file that had permission to be written to the day before, does not have that same access the next day - yes, it does piss you off - believe me, I know!

All Macs come with a utility called Disk Utility.  It is located in the Finder in the Utilities Folder.  From this app, one can "repair" the file permissions of all files on a Mac.  Here's how to use Disk Utility to verify and/or repair permissions:

1.  Go in to Disk Utility: Finder > Utilities > Disk Utility.

2.  Click on the Mac's hard drive icon (upper-left).

3.  Now, go down one space to the name of your hard drive (usually named Macintosh).

4.  On the lower-left of the second window panel is a button that says Verify Disk Permissions.  Click it.

5.  Disk Utility will now verify and repair any permissions that may have gotten changed.

Some tips:

- Make sure all data files are closed (such as a text document) so Disk Utility can repair the file correctly.

- This should be done with hard drives and SSDD drives as well.

- Although Apple says you do not have to, reboot the Mac after Disk Utility is finished.  This will guarantee you're using the newly repaired permissions.

- You should do the above at least once a month to help your Mac run as smoothly as it can.

That's it.
