This document details how to use Apple's built in disk utility to attempt minor software repair in OSX.
Apple Disk Utility is a utility built into OSX that identifies and repairs minor problems with the hard drive. If a computer is unable to successfully complete any of these steps it should be booked in for software repair. When checking in make sure to get format approval as the drive will likely have to be formatted or replaced completely.
Mac OS 10.11+
That allows you to run Disk Utility, reinstall or wipe and install the system, access Terminal for command-line functions, and so on. Mac 911 can’t reply to—nor publish an answer to. If you’re having problems with a disk, Disk Utility can check the disk and repair problems it detects. How to repair a disk To browse the Disk Utility User Guide, click Table of Contents at the top of the page. System Disk Utility 2.6.2 for Mac OS X Server 1.2 is a Mac OS program that allows you to select which hard disk your computer will start up from. To startup your computer with Mac OS X Server 1.2. Disk1s1, the volume you boot from, mounted at /, shown in Disk Utility as Macintosh HD; disk1s2, ‘Preboot’, not mounted, hidden; disk1s3, ‘Recovery’, not mounted, hidden; disk1s4, ‘VM’, mounted at /private/var/vm, hidden; The last 3 are grouped as Other Volumes in Disk Utility. They're required by macOS and shouldn't be removed.
- Launch Disk Utility by opening Finder and navigating to Applications > Utilities > Disk Utility. If you are unable to boot into the users account then you can run Disk Utility from either the recovery partition or from the netboot environment.
- Click on the 'First Aid' button while selecting the hard drive on the left panel. Click the 'Run' option when prompted.
- If steps 1 and 2 were successful, run first aid again. This time select the partition (not the disk) on the left panel. Click Run when prompted.
- You will receive a prompt if repair was successful.
If any part of this process fails you will likely have to check it in for a format/reinstall. Remember to get format approval if possible for all software check-in cases.
Mac OS 10.6-10.10
- Launch Disk Utility by opening Finder and navigating to Applications > Utilities > Disk Utility. If you are unable to boot into the users account then you can run Disk Utility from either the recovery partition or from the netboot environment.
- Run 'Verify Disk' on the hard drive. If verification fails, you will be prompted to attempt 'Repair'. Only continue to step 3 if repair is successful.
- Select the boot partition (usually Macintosh HD) and run 'Verify Disk'. If verification fails, you will be prompted to attempt 'Repair'. Only continue to step 4 if repair is successful.
- Run 'Repair Disk Permissions' on the boot partition. Do NOT select 'Verify Disk Permissions'.
- You will receive a prompt if repair is successful.
Virtually every computer will make at least a couple file permission repairs, so don't worry if you see a handful of repaired files on a perfectly healthy computer.
