5. Repair hard drive permissions

Fixing hard drive rights is an outdated method with OS X El Capitan, a version that automatically protects file system permissions. If you are still using OS X Yosemite or below, please continue reading.

Fixing the right hard drive is an action you can do, regardless of time and even if your Mac has 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 Command + Space and then type Disk Utility into Spotlight ), select the main hard drive (e.g. Macintosh HD) and then click Repair Disk Permissions .

6. Verify and repair the drive

You can verify the status of the disk and file system in Disk Utility. In newer versions of macOS, Apple calls it the First Aid feature.

In most cases, it will not have any problems, but if something is detected, you must fix it immediately. To repair the drive, you must boot into Recovery Mode. Boot into Recovery Mode, reboot your Mac and hold Command + R until the apple logo appears.

Once Recovery Mode is enabled, select the main hard drive on your computer and click on Repair Disk or First Aid , depending on the operating system version you are using.

7. Reset Safari and clear Cache

Note: Safari cannot be reset on recent versions of the operating system.

To reset Safari and empty the cache, launch Safari and select Reset Safari. For older versions of Safari, go to Preferences to clear the cache.

If you use a separate password management application, you must uncheck Remove saved names and passwords and back up all your accounts and passwords before being wiped.

On newer versions of macOS, 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 folder

Macs and most applications use a lot of cache, sometimes corrupted cache is also a cause of many problems. To clear the cache open the Finder , press Command + Shift + g and type ~ / Library / Caches .

Alternatively, just go to the home folder (~) and then to the subfolder of the Library. However, from OS X 10.7 (Lion) Apple has decided to hide the Library folder, so use the shortcut Command + Shift + g , or go to the Finder menu: Go> Go to Finder . will be faster.

Inside the Library, you will see the cache folder. Go to that directory and delete all content in it. Do not delete the contents of the Library, only the cache folder.

Repeat these steps for the cache directories below:

1. / Library / Caches
2. / System / Library / Caches

With these two directories, macOS will ask you to enter your device's password. When the content is cleared, restart the computer and then, empty the trash.

9. Update to the latest software version

Every software update, Apple patches security holes and fixes bugs. Perhaps the problem you are having is because the version of the operating system you are using is outdated. Therefore, please update to the latest version of macOS for your device.

10. Create a new user account

Sometimes, some problems are related to user accounts and the best solution is to create a new account. However, this may cause you to lose all your old data and settings. Only use this method if the problem is related to your account but cannot be solved by any other method. Before deleting your old account on your device, make a backup of all important data.

To create a new user account, open System Preferences> Users & Groups . Click on the lock icon below and select the plus sign . 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 a last resort. Before reinstalling the operating system, back up your data many times and across multiple devices. Also record some important settings that you can perform again on the machine.

Sometimes, Time Machine can help you regain a backed up user account, but most other cases do not have such luck.

The fastest way to reinstall macOS is to boot into Recovery Mode, erase the main hard drive and reinstall from the Recovery Console.

If none of the above fixes the problem on your device, it's best to take the device to an Apple service center for a careful review.
