This MacBook is able to boot LibreELEC 8, but not LibreELEC 9.
I do see the EFI volume in the mac bootloader when pressing Alt.
However, after selecting this volume, the scree remains black + high backlight.
This machine has 2 GPU:
- Intel HD Graphics 630
- Radeon Pro 560
I don't know which one is used by LE.
The version is master 4ad81f9, built from source. The same image works well on other PCs, including a MacBook Air 2013.
I know that this kind of machines are not the primary target of LE, but this is what I will be using for development of my LE fork (Lakka)
