What are disk permissions and why do they need repairing?
Disk permissions on macOS are used to keep your files secure. They’re designed so that certain programs (or other users if you share your Mac) can’t just dip into a system file they have no business with and modify it. They’d need permission to do that.
Transferring Information to Your Power Mac G5 You can use the Setup Assistant to automatically transfer information from another Mac to your new Power Mac G5.

Every file and folder on your Mac comes with an associated set of permissions. From the Apple Community:
“Many things you install in Mac OS X are installed from package files (whose filename extension is '.pkg'). Each time something is installed from a package file, a 'Bill of Materials' file (whose filename extension is '.bom') is stored in the package's receipt file, which is kept in /Library/Receipts/ in Mac OS X v10.5 and earlier. These files don't take up much disk space and you shouldn't put them in the Trash. Each of those '.bom' files contains a list of the files installed by that package, and the proper permissions for each file.”
Unfortunately, these permissions can easily become messed up unintentionally. It’s quite common for this to happen when installing and uninstalling apps on your system. And when it does, apps can find themselves with free reign to alter files and modify read-only files which can cause all kinds of permission errors and system issues such as lagging, freezing, or crashing.
If you notice anything out of the norm regarding system performance, the first thing you should do is troubleshoot those disk permissions.
Below we’ll show you two ways: the manual and the easy one. Choose the way that works best for you.
How to repair permissions on Mac: The manual way
Repair Permissions Mac High Sierra
If you’re running an older version of macOS, Disk Utility is the go-to tool for troubleshooting problems.
Why an older version?

Because as of macOS version 10.11 El Capitan, Disk Utility no longer comes with the option 'repair disk permissions'. Boooo!
Apple even removed the command line:
But there’s a method to the madness. macOS now comes with a feature called System Integrity Protection (SIP) which is designed to automatically repair file permissions during software updates and system changes. SIP works by restricting the root account so that it can’t do things like modify protected locations and processes such as /System and /usr. This should prevent malware from gaining root permissions and infecting your system files.
Anyway, back to using Disk Utility to repair disk permissions. If you’re running a pre-El Capitan version of macOS, follow these steps:
- Press Command + Space to open Spotlight, type in “Disk Utility”, and hit Enter.
- Select Macintosh HD from the left sidebar menu.
- Click on the First Aid tab.
- Click on Verify Disk Permissions. By taking this step, Disk Utility will work through your hard drive to detect broken or misbehaving permissions and list them for repair. This might take a few minutes but you can check the Show details box to keep an eye on its progress.
- Click on Repair Disk Permissions and wait while Disk Utility runs through the identified permissions to fix them.
If disk permission issues have played such havoc that your Mac won’t boot correctly, it’s possible to access Disk Utility in Recovery Mode. Do this by holding Command + R during bootup.
If you’re installing a newer (or older) version of macOS on top of your existing operating system, Mac will perform a disk permission repair as a part of the installation so that you start from a clean slate.

But worry not, CleanMyMac X is the hero you need.

- Improper functioning of applications.
- Inability to move or delete files.
- Inability to access files.
If you Mac appears to be running fine, it’s still worth running repairs every so often to ensure it stays that way. Not all broken permissions affect performance but that doesn’t mean they shouldn’t be fixed.
