Mac Os X Fix Library Permissions
- Melissa Holt shows us how to resolve premissions problems after a Mac migration, including tricks and tips to make it easier. Saying “macOS needs to repair your Library,” like this.
- Beginning with Mac OS X 10.7 (Lion) or later, the Library folder located in a user's home folder /Library is hidden by default. This tutorial covers several methods to make the Library folder visible again. Instructions Method 1: Using the Finder's Go menu. Hold down the Option key and open the Go menu in the Finder; Select Library from the.

If you run into odd slow-downs or problems with loading specific programs and services, then sometimes this can be caused by the inability of the program or service to access a necessary resource on disk, be it a preference file, or a core resource like a framework, font, or audio unit. In these cases you might see an error, but also might just see the problematic behavior.
If you log in to an account with administrator privileges, but are still unable to install, your disk permissions could be damaged. Double-click Disk Utility. Select the volume in the left pane for which you want to repair permissions. Click the First Aid tab. Select the volume to which you want to.
Fixing permissions in OS X is relatively straight-forward, and simply requires you to open Disk Utility, select your boot drive, and then click the “Repair Permissions” button in the First Aid tab. Doing this will have the system check various receipt and bill of materials files in the Macintosh HD > Library > Receipts, and hidden var > db > receipts folders, and reset the permissions for files on disk to those represented by the files in these receipts. This is all done automatically, so you only have to click the “Repair Permissions” button and wait for the routine to end.
While a global permissions fix like this can be useful, it does not touch your home folder, and this is often where a permissions snafu can result in a headache or two.Your home folder needs a specific permissions setup, not only to ensure full and proper access by your account, but also for security to prevent other people on the system from accessing your private files. To ensure your account’s permissions are set up properly, you need to first strip any access control lists from the account, and then use Apple’s password utility to reset home folder permissions:
In Apple’s password reset tool, clicking this button will reset the selected account’s permissions to their defaults.
- Strip ACLs from your account by running the following command in the Terminal:
- Boot to Recovery mode by holding Command-R at startup.
- After selecting your language and are at the Tools window, choose the “Reset Password” option from the Utilities menu, or if this is not available, choose Terminal and then run the command “resetpassword” (all one word).
- In the password reset utility, select your hard drive, and then select your user account from the drop-down menu.
- With your account selected, click the “button to reset home folder permissions and ACLs” at the bottom of the password reset tool’s window.
This reset should only take a few moments at most to complete, and then you can reboot your system and log back into your account, to see if the changes have made a difference for whatever problem you have been experiencing.
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.
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
If you’re running an older version of macOS, Disk Utility is the go-to tool for troubleshooting problems.
Font library mac luna. 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 Performance (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:
1. Press Command + Space to open Spotlight, type in “Disk Utility”, and hit Enter.
2. Select Macintosh HD from the left sidebar menu.
3. Click on the First Aid tab.
4. 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.
5. 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.
How to repair disk permissions on Mac: The easy way
For users of macOS versions El Capitan and newer, the removal of Repair Disk Permissions means you have no troubleshooting solution to turn to in if your Mac is ailing.
But worry not, CleanMyMac X is the hero you need.
CleanMyMac is like Disk Utility in that it does all of the heavy lifting for you to verify permissions and repair your Mac’s disk.
Even System Integrity Performance running quietly in the background doesn’t prevent certain issues from arising. If you’re suffering from any of the following problems, boot up CleanMyMac and have it take care of business:
- 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.
Repairing Disk Permissions in a few clicks
