Are you having trouble booting from a USB flash drive on a Mac with M1 processor and security system from Apple? The old method of pressing the option key or command to go to the boot menu setting or firmware setting and boot from the flash drive no longer works. In this blog post, we will provide you with a solution to this problem.
Firstly, shut down your computer and then press and hold the power key to start it. You will see some directions on the screen. Continue holding the power key until the startup option appears. From there, you can select the “macOS HD” and access the BIOS settings.
If you encounter issues with the flash drive not being detected, it could be because the flash drive is not compatible with the M1 chip. Make sure to create a new bootable flash drive that is compatible with your Mac.
Once you access the BIOS settings, you can check the disk utilities and advanced settings for the latest Mac. You can also adjust the startup security settings according to your preferences.
We hope this solution helps you successfully boot from a USB flash drive on your Mac with M1 processor and security system from Apple. If you have any questions, feel free to leave a comment below. Thank you for reading and have a great day!
