5. Fix hard drive permissions
Fixing hard drive permissions is an outdated approach to OS X El Capitan, a version that automatically protects file system permissions. If you are still using OS X Yosemite or lower, please continue reading.
Fixing your hard drive permissions is something you can do, regardless of the time and even if your Mac should have no problems.
To do this, open Disk Utility (this depends on the version of the operating system you are using, you can find it in Launchpad or hide the combination. Command + Space then type Disk Utility into the Spotlight), choose main hard drive (eg Macintosh HD) then click Repair Disk Permissions.Disk Utility on old macOS versions
6. Verify and repair the drive
You can verify the status of the drive and the file system in Disk Utility. In newer versions of macOS, Apple calls it the First Aid feature.Disk Utility on macOS Catalina
In most cases it shouldn't have any problems, but if something is found, you must fix it immediately. To repair the drive, you must start Recovery Mode. Start Recovery Mode, reboot your Mac and hold down the key combination Command + R until the apple logo appears.
With Recovery Mode enabled, select the primary hard drive on your machine and click Repair Disk or First Aid, depending on the OS version you are using.
7. Reset Safari and clean the Cache
Note: Safari cannot be reset on recent operating system versions.
To reset Safari and clear the cache, start Safari and select Reset Safari. For older versions of Safari, go to Preferences to clear all caches.Reset Safari
If you use a separate password manager, you must uncheck it Remove saved names and passwords and back up all of your accounts and passwords before being wiped.Clear Safari history
On newer macOS versions, clear the Safari cache by going to Safari> Clear History. Or you can delete the data on each website by going to Safari> Preferences> Privacy> Manage Website Data.
8. Delete the cache folders
Macs and most apps use caches a lot, and sometimes a corrupt cache is the cause of quite a few problems. To clear open cache Finder, press the combination Command + Shift + g and type ~ / Library / Caches.Cache folder in Finder
Alternatively, just go to the home folder (~) and then into the Library sub-folder. However, from OS X 10.7 (Lion) Apple decided to hide the Library folder, so use the keyboard shortcut. Command + Shift + g, or go to the Finder menu: Go> Go to Finder... will be faster.
Inside the Library, you will find the cache folder. Go to that folder and delete all the content in it. Don't delete the contents of the Library, just delete the cache folder.
Repeat these steps with the following cache directories:
- / Library / Caches
- / System / Library / Caches
With the two folders above, macOS will ask you to enter your device's password. Once the contents have been erased, restart the device and then delete the trash.
9. Update to the latest software version
Every time it updates its software, Apple fixes its security holes and fixes bugs. Perhaps the problems you are having are due to the outdated version of the operating system you are using. So, please update to the latest version of macOS for your device.
10. Create a new user account
Sometimes, some problems happen related to the user account and the best workaround is to create a new one. However, this can cause you to lose all old settings and data. Use this method only if the problem is account-related that can't be fixed by any other method. Before deleting the old account on the device, please back up all important data.Add a user to the device
To create a new user account, open System Preferences> Users & Groups. Click lock icon below and select plus. Follow the steps to set up a new account for the device.
11. Reinstall macOS
Reinstalling the operating system is the most dangerous method, but sometimes it's the last resort. Before reinstalling the operating system, back up your data multiple times and across multiple devices. Also record some important settings that you can perform again on your device.
Time Machine can sometimes help you get back a backed up user account, but most other times don't have such luck.
The fastest way to reinstall macOS is to boot into Recovery Mode, erase the primary hard drive, and reinstall from Recovery Console.
If all of the above still does not help fix the error on your machine, it is best to bring the device to an Apple service center for careful consideration.
