Disk Utility User Guide
Disk Utility can fix certain disk problems—for example, multiple apps quit unexpectedly, a file is corrupted, an external device doesn’t work properly, or your computer won’t start up. Disk Utility can’t detect or repair all problems that a disk may have.
If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional checks, and then checks each volume. If you run First Aid on a volume, Disk Utility verifies all the contents of that volume only.
In the Disk Utility app on your Mac, choose View > Show All Devices.
Note: If you’re checking your startup disk or startup volume, restart your computer in macOS Recovery, select Disk Utility in the macOS Utilities window, then click Continue. If you check your startup volume (Macintosh HD), make sure you also check your data volume (Macintosh HD - Data).
In the sidebar, select a disk or volume, then click the First Aid button .
If Disk Utility tells you the disk is about to fail, back up your data and replace the disk—you can’t repair it. Otherwise, continue to the next step.
Click Run, then click Continue.
If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done. You can click Show Details to see more information about the repairs. Otherwise, you may need to do one of the following.
If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. You need to check each file in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.
If you can replace a file or re-create it, delete it.
If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted.
If Disk Utility can’t repair your disk, or you receive a report that the First Aid process failed, try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall macOS, then restore your backed-up data.
If your Mac has a Fusion Drive and you see a flashing question mark or alert, see the troubleshooting section of the Apple Support article About Fusion Drive, a storage option for some Mac computers.

Gatekeeper has been built into OS X since the days of Mountain Lion, but if you open up Spotlight and search for it, you won't find an app or system preference by that name. Gatekeeper is what Apple calls OS X's defense against 'malware' — malicious software. Gatekeeper restricts how software from third-party developers runs on your Mac, so understanding what it is and how it works can be pretty important.
What is Gatekeeper and should you use it?
Apple offers the Mac App Store as a safe and convenient way to download apps for your Mac (and to update system software too). It operates similarly to the App Store on iPhone and iPad. But there's one key difference: Unlike the iPhone and iPad, the Mac isn't restricted from running software just from the Mac App Store. You can download Mac apps from anywhere.
Given that reality, Gatekeeper helps OS X makes sure that app is safe to run, even if it's not from the Mac App Store. Gatekeeper checks for the presence of a digital certificate embedded in the app itself that tells the Mac the app is from a signed developer who has registered with Apple.

The default setting for Gatekeeper on most Macs is 'Mac App Store and identified developers.' (The exception is OS X Lion 10.7.5. This was the first time Apple offered Gatekeeper, and its default setting is 'Anywhere.') If you try to change the setting to 'Anywhere', the Mac will warn you against it (though it will make the change if you tell it to.)
You can shut off this protection, though I wouldn't recommend it. Gatekeeper is there to stop malware from getting on your Mac, and that's a good thing.
How to use Gatekeeper
- Open up your Mac System Preferences.
- Click on Security & Privacy.
- Security & Privacy shows your Mac's security settings. The setting that says 'Allow applications downloaded from' are the Gatekeeper settings.
- If you want to change those settings, click on the lock icon you see in the lower left hand corner of the Security & Privacy window.
- Enter your administrator password.
- Change the setting to Mac App Store, Mac App Store and identified developers, or Anywhere. Use Anywhere with extreme caution!
- Click the lock when you're done to save changes and prevent any more changes from being made.
