Try different combinations to replace Command + R keys
Command-R won't bring all Mac models in Recovery Mode. If your Mac has a T2 or Apple M1 chip, the key combination for booting into macOS Recovery Mode is different.
To check if your Mac has a T2 security chip or an Apple M1chip, you should go to support.apple.com or open About This Mac from the Apple menu bar if your Mac is bootable.
Boot a T2-based Mac in Recovery Mode:
- Press down the Option/Alt + Command + R keys when starting or rebooting your Mac.
- Release the keys until seeing the Apple logo or spinning globe.
Boot an Apple M1 Mac in Recovery Mode:
- Hold down the power button until seeing the words "Loading startup options".
- Choose Options and click Continue.
- Type the admin password.
If other key combinations like Command-Option-R still not working to boot your Mac into Recovery Mode, reset the NVRAM.
NVRAM/PRAM stores setting information on Mac, including startup disk selection, recent kernel panic, display resolution, etc. If NVRAM has some errors, problems like Command-R failing to bring out Recovery Mode may happen.
So, try to reset NVRAM/PRAM, and then reboot your Mac in Recovery Mode. Note that M1 Mac can auto-reset NVRAM if needed, so you can skip this job if you're using M1 Mac.
How to reset NVRAM/PRAM:
- Shut down your Mac machine and wait 10 seconds.
- Press the power button and hold down the Option - Command - P - R keys at the same time.
- Release the keys once you hear the second startup sound from your Mac. If it's a T2-based Mac, release the keys when seeing the Apple logo appear and disappear twice.
Command R not working to reset Mac or reinstall macOS, what to do?
Regrettably, your Command R still can't work to bring your Mac in Recovery Mode after trying all the fixes above. A blank or black screen occurs after pressing Command R keys during Mac startup.

Different from Recovery Mode, the Internet Recovery Mode loads recovery options from Apple's server over the Internet.
To start up an Intel-based Mac in Internet Recovery Mode, you should:
- Turn off your Mac and wait a few seconds.
- Press the power button and simultaneously hold down the Option-Command-R or Shift-Option-Command-R key combination.
Note: If you use Shift-Option-Command-R during startup, it will offer the macOS that came with your Mac. If you use Option-Command-R during startup, it will supply the latest compatible macOS.
- Release the keys when the spinning globe appears on the screen. Sometimes, a message "Starting Internet Recovery. This may take a while." will appear too.
- Select a Wi-Fi and type your Wi-Fi password when asked. If your Mac fails to connect the Wi-Fi, it won't enter in Internet Recovery Mode.
- Wait until you see the recovery utilities. The waiting time depends on your Internet speed. During this period, ensure your Mac is charged.
