macOS Recover – Process

macOS Recovery is the built-in recovery system on your Mac.

You can use the apps in macOS Recovery on an Intel-based Mac to repair your internal storage device, reinstall macOS, restore your files from a Time Machine backup, set security options, and more.

Reinstalling macOS requires an internet connection. To connect to the internet, you can use a wireless or wired network connection. If you’re trying to connect to Wi-Fi through a captive portal (for example, at a coffee shop, library, or hotel) or an enterprise network, you might not be able to access the internet in macOS Recovery.

This covers the start-up mode using the Option + Command + R or the Shift + Option + Command + R keys.

Note: Internet Recovery Mode takes longer to boot – this is normal.

Note: It is advised to be wired to Ethernet for this mode.

Note: Internet Recovery only works if the MacBook has OS X 10.12.4 or later installed due to a Bookroom update

Things you can do in Internet Recovery Mode:

• Restore from Time Machine backup
• Reinstall macOS
• Go to Apple Support for help online
• Use Disk Utility to partition, repair, erase, and format drives
• Add or remove an EFI password (must know the password if removing)
• Troubleshoot network connection
• Open Terminal from Recovery Partition (reset user password, disable/enable SIP, change the date, etc.)
• Select a different startup disk
• See the Installer Log
