Step One
Boot into Recovery Mode
To access Recovery Mode, turn off your Macbook, turn it on and hold the Command (⌘) and R keys. Keep holding them through the chime sound until you see the Recovery Screen below…
Macs support a variety of file systems. By default, they format disks with the Mac-only OS X Extended file system. But, if you plan on using an external drive with both Macs and PCs, you should format the disk with the exFAT file system instead. Reasons for Mac Boot from USB. Booting the Mac from USB in a way gives the power back.

Caveats, notes and disclaimers.
- You need an uefi bootable image. (we’re uncertain of other workarounds for grub at this time)
- You may not have any access to the internal drive. Not sure if it is a linux driver issue or some sort of on chip security, but so far, no access.
- Leaving ‘external boot allowed’ is a risk that if stolen, someone might be able to access the internal drive.
- The law of unintended consequences. Apple rarely supports playing around with bootable O/Ss, you could brick an extremely expensive device.
- Apple does have further detail on the T2 security chip and how to use it. Read more before playing around too much in there.
The better option
If you are looking for a great laptop to run NinjaStik we recommend getting an IBM Lenovo T430i for ~$140 and using it. The T430i is one of the best value for $ deals to run a daily use linux based personal laptop. It’s ugly but it is a solid machine.
