Open Disk Utility
In general, you can just open Disk Utility from the Utilities folder of your Applications folder. However, if your Mac doesn't start up all the way, or you want to repair the disk your Mac starts up from, open Disk Utility from macOS Recovery:
- Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
- Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
- Intel processor: Turn on your Mac, then immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R.
- You may be asked to select a user you know the password for. Select the user, then click Next and enter their administrator password.
- From the utilities window in macOS Recovery, select Disk Utility and click Continue.
Select your disk in Disk Utility
Choose View > Show All Devices (if available) from the menu bar or toolbar in Disk Utility.
The sidebar in Disk Utility should now show each available disk or other storage device, beginning with your startup disk. And beneath each disk you should see any containers and volumes on that disk. Don't see your disk?
Mac Utility Wagon
In this example, the startup disk (APPLE HDD) has one container and two volumes (Macintosh HD, Macintosh HD - Data). Your disk might not have a container, and it might have a different number of volumes.
Repair volumes, then containers, then disks
For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.
In this example, the last volume on the disk is Macintosh HD - Data.
Click Run to begin checking the selected volume for errors.
- If there is no Run button, click the Repair Disk button instead.
- If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.
- If you're asked for a password to unlock the disk, enter your administrator password.
After Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself.
In this example, the repair order is Macintosh HD - Data, then Macintosh HD, then Container disk3, then APPLE HDD.
If Disk Utility found errors that it can't repair
If Disk Utility found errors that it could not repair, use Disk Utility to erase (format) your disk.
If your disk doesn't appear in Disk Utility
If Disk Utility can't see your disk, it also can't see any containers or volumes on that disk. In that case, follow these steps:
- Shut down your Mac, then unplug all nonessential devices from your Mac.
- If you're repairing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
- If your disk still doesn't appear in Disk Utility, your Mac might need service. If you need help, please contact Apple Support.
A lightweight and practical utility that makes it easy for you to simultaneously install multiple kext files and repair kext permissions for you system's folders

Loadable kernel modules are usually used to add support for new hardware and or filesystems and for adding system calls.Easy to use and drag-and-drop-based kernel extension installer for OS X
When the functionality provided by any given loadable kernel model is no longer needed, it can be easily unloaded in order to free up memory and other resources.
Kext Utility is a straightforward app that enables you to easily install loadable kernel modules, known as kernel extension (kext), a fact that makes it an essential utility for Hackintosh installations.
The advantage provided by a loadable kernel module is that the operating system does not have to include all possible anticipated functionality already precompiled into the base kernel.
Otherwise, most of the existing functionality would require memory that is not used and force the user to rebuild and reboot the base kernel every time a new functionality is added.
Automatically repairs system folder permissions and rebuilds system caches
Kext Utility can also be used to repair permissions for all system folders and rebuilt system caches. The repair process starts as soon as you launch the utility. Once completed, you just have to drag and drop the kext files you want to install. onto Kext Utility’s main window.
Thanks to Kext Utility you can also update records of the unsigned installed kexts in the AppleKextExcludeList.kext file, pack kext files to mkext cache files and vice versa.
Mac Utility Tool
In conclusion, Kext Utility is a quite practical and intuitive OS X utility for any user interested in hackintosh installations and kext cache file reparation.
