Why is Mac not booting from USB?

There could be several reasons why a Mac is not booting from a USB drive. Here are some steps you can follow to troubleshoot the issue:

1. Incorrect bootable USB drive: Ensure that the USB drive is correctly prepared as a bootable device with the necessary system files. Double-check the process and reformat the USB drive if needed, following Apple’s guidelines or reputable sources.

2. Incompatible USB port: Try using a different USB port on your Mac. Sometimes, certain ports may not support booting from external devices. Switching to a different USB port could resolve the issue.

3. Startup disk settings: Check the Startup Disk settings in your Mac’s System Preferences. Go to the Apple menu, then select System Preferences > Startup Disk. Ensure that you have selected the correct USB drive as the startup disk. If not, select it and restart your Mac.

4. PRAM or NVRAM reset: Performing a PRAM (Parameter Random Access Memory) or NVRAM (Non-Volatile Random Access Memory) reset might help resolve booting issues. Restart your Mac and hold down the Option, Command, P, and R keys simultaneously until you hear the startup sound for the second time. Release the keys and check if the USB drive boots properly.

5. Secure Boot settings: If you have a newer Mac model with Apple Silicon, check the Secure Boot settings. Go to the Apple menu, then select System Preferences > Startup Security Utility. Ensure that the settings allow external bootable devices. Adjust the settings if necessary and try booting from the USB again.

6. Hardware issues: If none of the above steps work, it is possible that there may be a hardware issue with your Mac or the USB drive itself. Try using the USB drive on another Mac or try a different bootable USB drive on your Mac to determine if the problem lies with the Mac or the USB drive.

Remember to back up important data before attempting any troubleshooting steps, and consider seeking professional assistance if you are unsure or uncomfortable with performing the troubleshooting on your own.
