What Does Disk Repair on Mac Do and How it Improves the Performance

Mac’s have a built-in tool called Disk Repair to fix certain problems. It can be useful in the following situations:

  • Mac won’t start up
  • Files on your Mac are corrupted
  • The external device won’t work properly
  • If you Mac behaves strangely after a hard restart or after a power failure
  • Performance of your Mac has degraded
  • As part of general maintenance

How to run Disk Repair?

You can perform Disk Repair on both your external drives as well as on your Mac. If you are repairing an external drive, on the dock, open Finder, go to Applications > Utilities and proceed to step 3.

In order to repair a disk that is running on your Mac system, you will have to go through Recovery mode and follow the steps below.

  1. Restart your Mac
  2. When your Mac restarts, Hold Command and R keys until the Apple logo appears
  3. Select Disk Utility and click Continue
  4. Then, from the left menu, choose the disk that needs repair
  5. Click on First Aid
  • If Disk Utility reports the disk is about to fail, you should backup your data and replace the disk. If not, proceed with the steps below.
  1. Click Run
  • If Disk Utility reports that disk appears to be Ok or has been repaired, you’re good.
  • If it reports error messages like ‘Overlapped extent allocation’, maybe some files occupy the same space on your disk. You will have to further examine each file in the list. Delete the files that can be replaced to solve the issue
  • If it reports Disk Utility can’t repair your disk or it reports ‘The underlying task reported failure’, try to run Disk Repair again

If Disk Repair is successful, your Mac problems are solved and performance improved. However, if running Disk Repair doesn’t help solve the issue, reformat your device and reinstall OS.
