Repairing permissions may speed up your Mac

Application permissions, which are installed with some apps, tell OS X users what they can do with specific files. These permissions can change over time and cause issues with your Mac. Here is how to verify if your computer has any of these permission conflicts and how to repair them, which may give your Mac a performance boost.

First, let’s open Disk Utility by selecting “Go” in the menu bar, then select “Utilities.” In the Utilities window, double-click “Disk Utility.”

To the left, you’ll see a list of your drives. For example, on my iMac, I see my Hitachi 250 GB drive, my Macintosh HD (yours may be named something similarly) and my SuperDrive, which is my CD/DVD drive. Select “Macintosh HD,” which is an extension of my Hitachi Drive, which has all my startup apps on it. In the middle, make sure the “First Aid” tab is selected and you should checkmark the box: “Show details.”

Below, you’ll see two buttons: “Verify Disk Permissions” and “Repair Disk Permissions.” First, click “Verify Disk Permissions.” In the middle window, it will indicate it is “Verifying permissions for “Macintosh HD” and it will begin to list any permission conflicts it finds. This process may take up to 10 or more minutes, depending on the size of your drive, the number of apps you have installed and how many errors it may find.

Once it has finished scanning your system, you can see from the list how many permission issues your system has and what they are. Next, click the “Repair Disk Permissions” and it will begin to repair those listed issues. Again, this process may take some time so be patient. Once the repair is complete, close the open windows and reboot your Mac.

There is another way to improve the performance of your Mac by limiting the number of applications that start up when you turn on your Mac. By limiting startup applications, you can improve your boot up time as well.


Open your “System Preferences” and then select “Users & Groups.” Next, click the tab: “Login Items” and you’ll see a list of all the applications at start up. Highlight each app you don’t want to auto start and then at the bottom, click the “-“ sign to remove it. On my Mac, the only application I have at start up is the “SpeechSynthesisServer” application. If you remember several articles ago, I showed you how to have the time announced every hour or quarter hour, this is what this application does and I like having it start up automatically. You may opt to have nothing start up. Make your choices and then close the window.
