What is macOS Recovery and how do I access it?
macOS Recovery is a built-in feature in Mac computers that allows you to start up your Mac from a separate boot environment, which can be used to diagnose and repair issues with your Mac’s startup disk. To access macOS Recovery, restart your Mac and immediately hold down the Command (⌘) + R keys. This will boot your Mac into the Recovery mode.
Alternatively, if your Mac is using an Apple T2 chip or Apple M1 chip, you can access Recovery mode by restarting your Mac and immediately holding down the Power button until you see the startup options window. From there, select the “Options” icon and click “Continue” to enter Recovery mode.
What are the different types of macOS Recovery modes?
There are two types of macOS Recovery modes: Internet Recovery and Local Recovery. Internet Recovery downloads the Recovery environment from Apple’s servers, while Local Recovery uses a local copy of the Recovery environment that is stored on your Mac’s startup disk. Internet Recovery is useful if your Mac’s startup disk is damaged or corrupted, while Local Recovery is faster and more convenient if your Mac’s startup disk is functioning properly.
Additionally, if your Mac is using an Apple T2 chip or Apple M1 chip, you can also access a third type of Recovery mode called “Recovery Assistant”. This mode allows you to restore your Mac to its factory settings and reinstall macOS.
How do I reinstall macOS from macOS Recovery?
To reinstall macOS from macOS Recovery, select the “Reinstall macOS” option from the Utilities window. This will launch the macOS installer, which will guide you through the process of reinstalling macOS. Make sure to select the correct disk and partition to install macOS on, and follow the on-screen instructions to complete the installation process.
Keep in mind that reinstalling macOS will erase all data on the selected disk, so make sure to back up any important files or data before proceeding. Additionally, if you’re using a Mac with an Apple T2 chip or Apple M1 chip, you may need to enter your Apple ID and password to authenticate the installation process.
Can I use macOS Recovery to repair my Mac’s startup disk?

From there, you can select your startup disk and click the “First Aid” button to run a diagnostic test and repair any issues that are found.
Additionally, Disk Utility also allows you to erase and reformat your startup disk, which can be useful if you’re experiencing issues with your Mac’s startup disk and need to start from scratch. However, keep in mind that erasing your startup disk will delete all data on the disk, so make sure to back up any important files or data before proceeding.

Resetting your Mac’s NVRAM and SMC can be useful if you’re experiencing issues with your Mac’s display, keyboard, or other hardware components.

To access Migration Assistant, select the “Utilities” menu and click “Migration Assistant”.
