I'm trying to install Debian 9.5.0 netinst on a
MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports), but can't even boot the installer. I took the following steps:
- I made a live USB with Etcher of
- I changed the secure boot settings in the Startup Security Utility to No Security https://support.apple.com/en-gb/HT208330
- I rebooted the laptop holding the
⌥ Option Keyat startup
- I selected EFI boot option.
This is as far as I got as I got the message
A software update is required to use this startup disk. This had an option to update which I did, I then reattempted step 3 and 4 and got the same message.
Does anyone know if it is even possible to install on this version of MacBook Pro?
