macOS Recovery (often referred to as Mac Recovery Mode) was introduced back in 2010 with OS X 10.7 Lion. This Recovery HD partition contains the latest version of the macOS you installed on your Mac and makes it possible to troubleshoot issues with your Mac. It is a useful tool that the majority of Mac users will never need to use unless one of the following applies:
How to start Mac in Recovery Mode
The most often used way to enter Recovery Mode (on a Mac with an Intel processor) is this:
- Click on Apple logo at the top left of the screen.
- Select Restart.
- Immediately hold down the Command and R keys until you see an Apple logo or spinning globe. You will see the spinning globe if the Mac is trying to start macOS Recovery via the internet because it is unable to start from the built-in recovery system.
- Eventually your Mac will show the Recovery Mode Utilities window with the following options:
However, there are a number of different key combinations you can use to boot in Recovery mode depending on what you want to do, we detail these below.

If you have a new Mac with an Apple processor, such as the M1 Macs introduced in November 2020, you need to enter Recovery a different way from the one detailed above.
- Turn off the Mac.
- Press the on button and keep it pressed.
- Eventually the Apple logo will appear with text below it informing that if you continue holding the power button you will be able to access startup options. Keep pressing that button.
- Eventually you will be able to select Options > Continue and this will open up Recovery.
Which keys to use for macOS Recovery Mode
Depending on what you want to do with macOS Recovery there are a number of key combinations to use during startup – these options work on an Intel-powered Mac:
Command + R
Use this if you want to install the latest version of macOS that you had installed on your Mac (it won’t install a newer version if you hadn’t upgraded). Note that if you’re selling or giving away a Mac that is using OS X El Capitan or earlier you should also use Command + R – this will make sure that the installation isn’t associated with your Apple ID.
Option/Alt + Command + R
Use this if you want to upgrade to the latest version of macOS that is compatible with your Mac.
Shift + Option + Command + R
This will install the version of macOS that came with your Mac, or the one closest to that version if it isn’t available as a download.

Startup Security Utility
This will allow you to make sure your Mac starts up from a trusted startup disk. Macs with the T2 chip have more options here including Firmware password protection and Secure Boot and External Boot options.
It also gives you access to Firmware password protection. A firmware password prevents users who don’t have the password from starting up from any disk other than your designated startup disk. Not every Mac has this option. Click Turn On Firmware Password. Enter a password and click Set Password. Then quit and go to Apple > Restart.
The Network Utility app gives you access to tools and information that can help you with problems with your network connections. Read more about fixing network problems here. Click on the Network Utility option if you want to test ping on your Mac (we have a guide to testing Ping on a Mac here).

- Hold down Option/Alt-Command-R or Shift-Option/Alt-Command-R at startup to force macOS Recovery to boot over the Internet.
