Boot M1 Mac & Intel Mac Off External USB Drive 

Great Video! Just what I needed!

Weird - I created a bootable USB for Cataline and I can see it on the desktop just like your video but I cannot boot to the device.

Thanks, pressing the power button continuously did the trick.

Can you boot Windows from an External USB Drive onto M1 Mac without using a Virtual Machine?

How can I do the security settings without and admin account (I don't have any MacOs on my Mac)

Is the RED Flash behind Apple LOGO a normal thing? (3:36) I notice mine does the same thing too.

Can I do it in a Mac Air M1 lock for iCloud?

how do you downgrade the m1 Mac from Big Sur?
