My company provided me with a secure boot stick from ECOS which shall boot Linux on any Mac or PC when plugged-in. However, my MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports, BigSur Version 11.2.3) does not detect the bootable device when I press option after having started. According to Disk Utility, it is a FAT16 system which prints me an error if I press mount in disk utility. Does anyone know a workaround?

As I need to use this stick for working from home, I really appreciate any kind of help!

Thanks in advance!

    I see two potential issues - 1. what format is the stick? 2. Is secure boot on? – Tetsujin Apr 3 at 10:04

    According to disk utility, it is a FAT16 system which prints me an error when I press "mount" in disk utility (I can provide pictures if needed). I have already disabled secure boot! – Hazards Apr 3 at 10:14
  • FAT16 ought to mount, but I'd be very surprised if it would boot. I'll have to leave the details to someone more au fait with newer MacBooks, but thank you for the additional info. Could you edit that into your original question for completeness? – Tetsujin Apr 3 at 10:43

    There is no "in general" getting a Mac vs PC to boot. They require very different things. – Tetsujin Apr 3 at 11:02

    It seems like the problem stems from Apple's T2 chip, though I've disabled secure booting. The stick can be booted from a 2016 MacBook Pro. – Hazards Apr 3 at 20:53
