Over time all our computers start to take a bit of a performance hit, things start to slow down, things just don’t run the way they should. Sometime applications lag and don’t do exactly what they are designed to do. There is a quick fix to all of this which should help speed up a few things. In disk utility there is a the option to repair disk permissions.
Repairing disk permissions goes through and corrects any errors with any permissions, which will make buggy applications correct themselves, and could speed up the overall performance of your mac.
To repair permissions first get to your utilities folder by clicking go in the finder, then selecting utilities.
Once in utilities open up disk utility.
In the left hand column select your hard drive.
Next select the first aid tab.
From there click Repair Disk Permissions
There is no need to click Verify Disk Permissions, selecting Repair Disk Permissions will verify and repair. This could take 5 minutes to 30 minutes, maybe longer depending on how long it has been since the permissions have been repaired. It is good to generally do this once a month, after you install an application, or run an update.
