Check your macOS version
If your Mac runs Mac OS X 10.6 Snow Leopard or older, there's no recovery partition available. Therefore, you can't enter Recovery Mode with Command-R.
Besides, if your Mac is running macOS Sierra launched in 2016 or earlier, it doesn't offer all options in Recovery Mode. It's not the fault of the Command-R.

How long should you press down the two keys and when to release them are crucial for entering Recovery Mode.
Here's the reference:
- Start or restart your Mac and immediately hold down the Command-R keys.
- The time between starting the computer and pressing the two keys shouldn't be over 3 seconds. If you can't measure the time, you can simultaneously press down the keys when Mac startup.
- Release the keys when seeing the Apple logo and progress loading bar.
- During this period, don't unplug the power cable or put your MacBook lid down.
Moreover, some of you may need to proceed with these additional steps to enter Recovery Mode:
- Enter the admin password when asked.
- Select the desired startup volume if you have multiple ones and click Next.
- Select an admin account if requested and type the password to enter Recovery Mode.
Check if your Mac has a T2 or Apple M1 chip
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.
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.
Check your keyboard & Mac USB port
Sometimes, the issue results from a faulty keyboard or USB port. You can connect another USB device to your Mac to check if the USB port is damaged. If not, try another keyboard.
If you are using a keyboard connected to Mac via Bluetooth, it's suggested that you should change it to a wired one.
How to boot in Recovery Mode when Command R not working
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 when Mac startup.
That's because the recovery partition on your Mac hard drive may be corrupted. Your built-in macOS Recovery Mode won't work. However, the Mac Internet Recovery Mode is an alternative. It also helps fix your Mac hard drive and reinstall macOS.
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.
Then, you can check and repair your Mac hard drive with Disk Utility First Aid or reinstall macOS.
For an Apple M1 Mac, if you fail to boot in Recovery Mode but make your computer connect to the Internet well, it will auto-switch to the Internet Recovery Mode.
If the Internet Recovery Mode is also unavailable or your MacBook won't turn on, you can use your Time Machine backup as your startup drive to boot up your Mac. Or, you can create a bootable USB drive to bring your dead Mac back to life.
