The built-in recovery program on your Mac is called macOS Recovery. You may repair your internal drive, reinstall macOS, modify the security policy for different disks, transfer files between two Mac computers, boot into safe mode, and more.
This built-in disk repairing tool is used to take measures when handling disk problems. Let’s explore different features of macOS recovery mode.
How to Startup your System in macOS Recovery
Select “Shut Down” from the Apple Menu on your Mac.
Wait for a complete shutdown of your Mac. When the screen is black, and all lights are off, your Mac is entirely off.
Now, hold down the “Power button” on your Mac while waiting for the message “Loading Startup options” to display.
After a few seconds, an options screen should appear. Choose “Options”, then press “Continue”, which should launch macOS Recovery, as shown in the image below.
Restore from Time Machine
The “Time Machine” is a built-in tool that routinely backs up your personal information, including programs, music, photographs, emails, and documents. You can restore deleted or inaccessible files if you have a backup.
You must enter “macOS Recovery Mode” in order to use “Restore from Time Machine” on a Mac powered by Apple Silicon.
Assuming you’ve created a Time Machine backup, Here’s how to do it.
First, If your system is on, switch it off. After clicking the Apple logo, select “Shut Down.”
When your Mac is off, wait for the message “Loading Startup choices” to appear while holding down the “Power button” on your Mac.
Next, press “Options”, then click “Continue”. You will then be sent to macOS Recovery.
Lastly, choose “Restore from Time Machine”, then follow the steps displayed on the screen.
Reinstall macOS Monterey
The most recent major version of Apple’s desktop operating system for Macintosh computers, macOS, is called Monterey.
The main reason for reinstalling macOS is that the operating system is utterly dysfunctional. Perhaps you are unable to work normally because error warnings appear frequently, the software won’t operate properly, or other usability problems.
This is how to reinstall your macOS Monterey.
The first step is to click the “Apple logo” and choose “Shut Down.”
Now, when your Mac is off, hold down the “Power button” on your Mac and wait for the message “Loading Startup options” to display
Next, select “Options”, then “Continue.”
Choose a user if prompted, then click “Next”. Enter the password for Admin Account. Afterward, you’ll be taken to macOS Recovery.
Finally, choose “Reinstall macOS Monterey” and then follow the on-screen instructions.
The system will guide you through the procedures to reinstall the most recent version of macOS Monterey.
Changing Security Policy
You can choose to run only your current operating system or enable any version of signed operating system software to operate by “Changing the Security Policy ” of a Mac.
Some applications use kernel extensions (.kext). For the software to run successfully on Apple silicon Macs, users must switch the security settings to “Reduced Security”. Here’s how to do it.
To begin, turn off your Mac by choosing “Shut Down” from the Apple Menu.
Wait 10 seconds after the system has shut down before pressing and holding the “Power button” on your Mac.
Then, select “Options” and click “Continue”.
Next, navigate to the Menu Bar and select “Utilities”. Now, click on “Startup Security Utility”.
Choose the startup disk you want to use from the list that appears, then click “Security Policy”.
After that, select Reduced Security > Allow User Management of Kernel Extensions from Identified Developers and hit “OK”.
If you modified the security policy, select an Administrator Account from the user pop-up box, type the password for the Administrator Account, and then click “OK”.
Lastly, you must restart your Mac for the changes to take effect. On the Apple Menu, select “Restart”.
Use First Aid to Fix Startup Disk
The First Aid feature within Disk Utility allows you to quickly examine the health of your Mac’s disk, volumes, and external devices. It contains numerous built-in features that can find and fix issues. It will scan the disk directory and assess whether it can repair any damage found.
To start, if your Mac is on, turn it off. Hold down the “Power button” for a few seconds. Continue holding down the button until “Loading starting options” appear beneath the Apple Logo.
The Startup Disk and Options screen will appear once you click this. Select “Options”, then click “Continue”.
Next, the macOS Utilities Screen will appear. Choose “Disk Utility”, then click “Continue”.
Now, select “Show All Devices” by clicking the “View Icon” next to Disk Utility.
On the left pane, you’ll see a list of all your internal and external disks. You must expand the starting disk, which is at the top of the sidebar, to access its containers and volumes.
Next is to choose a particular “Volume” and then click “First Aid”.
A prompt window will appear to confirm your action. Now, select “Run” to examine the volume for errors and make any necessary repairs.
Next, click “Done” after it’s finished, then repeat the previous steps to perform First Aid on the other volumes, containers, and disks.
Once your disk has been repaired, you can leave macOS Utilities by clicking the “Apple icon” in the Menu Bar and selecting “Restart” to have your Mac restart normally.
Tip: Start with the volumes while trying to repair a disk, then the containers, and finally the disk itself. When looking for disk errors, this produces the best results.
