The Mac operating system relies on disk permissions to ensure your computer security. These permissions ensure that various programs won’t just modify system files without you knowing.
It’s essential to repair disk permissions because they can lead to problems whenever they are damaged. Some of these problems include the inability to access files, delete or move them. In some cases, even apps have to suffer from that, which is something you want to avoid.
Use a third-party tool!
Third-party tools can be great, as these will make it easier to save time. Plus, a Mac cleanup tool will help ensure your device works smoothly and without a problem.
The best thing about using such a cleanup tool is that it won’t touch anything else so you can repair the permissions.
Or you can use this as a part of a more significant task of cleaning your Mac and speeding it up.
Is it possible to repair disk permissions manually?
- Open the Disk Utility via Spotlight
- Here you want to choose the Macintosh HD from the sidebar. These disk permissions are only on the main HD, so you don’t have to worry about any external storage here.
- From here, you want to choose the First Aid Tab
- Click on the option to Verify Disk Permissions.
- After the verification process is done, you need to press Repair Disk Permissions. Disk Utility will finalize the cleanup and repair of those broken disk permissions.
Can you control permissions for a specific app?
There are use cases where you want to control permissions for a single app.
- Right-click on the app and then press Get Info. Here you can go to the Sharing and Permissions settings. You can change the Read or Write permissions for every user.
- If you don’t have any permissions for some reason, the best idea is to update the Mac OS to the latest version. Then go to System Settings/ Users and Groups. Make the user an Admin, as that will usually remove any permission limit for the user.
Repairing disk permissions via the Terminal
If you have more in-depth knowledge regarding the Terminal, then you can attempt to solve any issues that way.
- Open up the Terminal
- Type this command “sudo diskutil resetUserPermissions / ‘id -u’”
- Enter the password when necessary
- That should solve the issue. However, if you encounter the error -69841, enter the “chflags -R nouchg” command, followed by “sudo diskutil resetUserPermissions / ‘id -u'”.
Solving disk permission problems can be difficult if you want to do it yourself. Thankfully, you can try to use a third-party tool to help you solve the issue, as that will repair the disk permissions without any manual tasks.
With that in mind, you can try to use your Mac’s tool or even enter the Terminal if you are a pro user. Repairing permissions will help prevent a variety of errors, and it’s necessary if you want to use your device adequately in the long term!
