If you have an older Mac, you should still periodically repair the permissions and other procedures to keep your Mac running well. This is a refresher for those machines that are unable to upgrade to macOS Sierra and High Sierra.
Repairing permissions on your Mac is an excellent way to keep your Mac running well and I recommend you perform this procedure whenever your Mac is running slow or may be experiencing system issues.
A good rule of thumb is to backup your data anytime you are going to run maintenance programs on your Mac. You can use Time Machine to do your backup, or you can use a flash drive or external drive. It is important you back up your personal files often.
Now, open Finder and then select “Applications.” Next, select the “Utilities” folder and then open “Disk Utility.”
To the left, select your “Hard drive,” which should be the top entry. Next, select the “First Aid” tab at the top and then “Run” when you see: “Would you like to run First Aid on (it will state your hard drive name here)? While it is running, select “Show Details.” In the window, it will detail what it is actually doing and at the end of the report, it will indicate if everything checks out OK. Select “Done” after it has completed.
Next, at the top left, select your start up drive. This should be the next entry, below your hard drive name. With it selected, you’ll see a breakdown of the contents of your hard drive. This is a great way to see what uses the most space and then you may want to remove apps/files you no longer need, to give you more space.
Now, select the “First Aid” tab at the top and then “Run” to begin the check for errors. This process may take a little longer than the process we did before. Again, select “More Details” to see what is happening and if you should be concerned about any issues with your Mac.
Once the process has completed, if you find there are errors on your Mac that cannot be fixed, you should seek the help of a professional to remedy the problems. Once you find your drive checks out OK, select “Done” and then close all the open windows.
