Resetting Your Mac Startup Disk
If you’re having trouble with your Mac, resetting your startup disk can help. Resetting your startup disk will erase all the data on it and reinstall the operating system, giving you a fresh start. Here’s how to do it:
Step 1: Back Up Your Data
Before you reset your startup disk, make sure to back up any important data that you don’t want to lose. You can use Time Machine or an external hard drive to back up your data.
Step 2: Restart Your Mac
Once you’ve backed up your data, restart your Mac and hold down the Command and R keys until you see the Apple logo. This will boot your Mac into Recovery Mode.
Step 3: Erase Your Disk
In Recovery Mode, select Disk Utility from the Utilities menu. Select your startup disk in the sidebar and click Erase. Choose a name for your disk and click Erase again to confirm.
Step 4: Reinstall macOS
Once your disk is erased, select Reinstall macOS from the Utilities menu. Follow the on-screen instructions to reinstall macOS on your Mac.
Step 5: Restore Your Data
Once macOS is installed, you can restore any backed up data using Time Machine or an external hard drive. Once everything is restored, you should be good to go!
