MacOS disc permissions protect and optimize system files, programs, and user data. These permissions may corrupt over time, causing errors, slowdowns, and program malfunctions. Disc permissions may be modified to improve speed and avoid difficulties.
This article covers three solid methods to repair disk permissions on Mac: Disc Utility, Recovery Mode, and Terminal. In addition, the EaseUS Data Recovery Wizard for Mac can monitor the health of your disk and recover lost data during repair. If you have troubles with your startup disc or an external drive, these options can help keep your Mac running smoothly.
Repair Disk Permission on Mac Using Disk Utility
Disk Utility in macOS manages storage devices and repairs disc permissions. Repair disc permissions on your Mac using Disc Utility:
Step 1. Launch Disc Utility from Finder > Applications > Utilities.
Step 2. Select the disc or partition to repair from the left menu.
Step 3. In Disc Utility, click the "First Aid" tab at the top-right. Click "Run" to verify and correct disc permissions.
Step 4. Disc Utility shows repair summary. If difficulties arise, it automatically fixes or suggests solutions.
Repairing disc permissions using Disc Utility is simple and effective, optimizing system and external drive performance. If issues continue, try Recovery Mode or Terminal for further solutions.
Repair Disk Permission Via Disk Utility in Recovery Mode
Recovery Mode is a more complex alternative for disc permissions problems when Disc Utility fails. Recovery Mode lets macOS users fix disc permissions without active activities. This mode's access relies on your Mac's hardware:
- Mac M1 or M2: Shut down. Hold Power when powering on to see Recovery Mode choices.
- Macs with Intel: Restart your Mac and hold Command + R until the Apple logo or spinning globe appears.
Follow the steps to repair Disc Permissions in Recovery Mode:
Step1. Access Recovery Mode for your Mac model by following these instructions.
Step 2. The macOS Utilities panel appears in Recovery Mode. Launch "Disk Utility" by selecting it and clicking "Continue."
Step 3. Select the "drive or partition" to repair from the left-hand list.
Step 4. Open "Disk Utility" and click "First Aid." Select "Run" to confirm.
Step 5. Disk Utility checks for and fixes problems. A summary of its acts will appear after that.
For ongoing disc permission difficulties, Recovery Mode assures a comprehensive repair. If this fails, try Terminal or other advanced troubleshooting.
Repair Disk Permission Via Disk Utility and Terminal
The Terminal allows command-line users to fix Mac disk permissions precisely. This approach is handy when Disk Utility fails, or deeper system-level adjustments are needed. To repair disk permissions using Terminal, follow the below steps:
Sep 1. Launch Terminal from Finder > Applications > Utilities by double-clicking.
Step 2. Enter the following Terminal command to reset user permissions:
Step 3. Enter your Mac's administrator password and hit Enter again. Note that password entry is hidden for protection.
Step 4. Use these commands to fix “Error -69841”:
To ensure accuracy, run the instructions sequentially.
Step 5. After resetting permissions, the Terminal will confirm. Finish by closing Terminal.
Pro Tips: How to Check the Disk Condition Using Disk Utility
Disk Utility's First Aid function may diagnose and fix faults with your Mac's internal disk or external storage device. This utility diagnoses and fixes disk issues. First Aid cannot fix the startup disk while macOS is operating. How to utilize First Aid and evaluate your disk:
Step 1. Launch Disk Utility from Finder > Applications > Utilities.
Step 2. Select the suspected problem disk or volume in the sidebar. If not, click "View" and choose "Show All Devices" from the list.
Step 3. Click "First Aid" at the top of Disk Utility.
Step 4. Disk Utility will check the disk for problems. Automatic repairs are attempted if faults are found. Click Run to continue.
The diagnostic procedure will momentarily disable your Mac. This may take longer, depending on disk size and problem severity.
