Internet Recovery Mode
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
Things you can do in Internet Recovery Mode:
- Restore from Time Machine back up
- Reinstall macOS
- Go to Apple Support help online
- Use Disk Utility to partition, repair, erase, format drives
- Add or remove an EFI password (must know password if removing)
- Troubleshoot network connection
- Open Terminal from Recovery Partition (reset user password, disable/enable SIP, change date, etc.)
- Select a different startup disk
- See the Installer Log
If you cannot startup in Recovery Mode by this startup combination, the current version of OSX may be too old, the internet connection may be faulty/insufficient, or the keyboard may be faulty. Try a wired keyboard, built-in Recovery, a different startup disk, or bootable installer.
