I have MacBook Pro 'Core i7' 2.3 17' Early 2011 (Model: A1279). Out of ignorance I've delete the previous OS (Yosemite) to install Windows – I had some difficulties but i could do it. Testing conducted by Apple in October 2020 on production 1.4GHz quad-core Intel Core i5-based 13-inch MacBook Pro systems with 8GB RAM, 256GB SSD, and prerelease macOS Big Sur.

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.

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.
Using a $140 laptop for linux and not risking your $5000 Macbook Pro is our recommendation.
