I put my computer through a lot, and once in a while the poor thing just starts to get a bit wonky.  Recently, after a big transition from Dropbox to Google Drive, things were hanging up pretty frequently.  After emptying the trash, purging my downloads folder, etc., it was still malfunctioning.

Then I remembered a critical part of Mac maintenance:  Repairing disk permissions.  It’s easy, takes a little bit of time (coffee break) and the best part is–your computer will probably run noticeably better.  My computer found over 8,000 permissions errors! Frankly, I am not quite geeky enough to know what a permission error is, but I know it matters.

Here’s how to do it:

1.) Do a Spotlight search for:  Disk Utility    (or, go through System Preferences…)

Make sure you are in the First Aid tab.

2.) Select the drive you want to repair.  It is most likely called “Macintosh HD“.  You probably have two–select the lower, ‘nested’ one (or, whichever one allows the “Repair Disk Permissions” option).

3.) Click Repair Disk Permissions.



4.) Sit back and enjoy.  Mine took over 15 minutes and provided a huge log of gibberish (that you can ignore).  And most importantly, it no longer hangs!

It also provides some interesting statistics about your files….over a million files and 200,000 folders! Yikes.  Time to get to work on that purging project I keep talking about….
