Hello! So I recently tried installing LibreELEC on my old macbook pro from mid 2011 (I've installed a ton of OS's on it without problem.)
After installing the OS from the USB stick, I rebooted and then it showed the Logo with the splash text "Just enough OS for KODI".
A few seconds later the screen flashes white and turns off, The fans are still running so there is still activity on the machine.
I read a post on here saying that old hardware might not be fully supported on recent versions so I decided to install the earliest version I could find, (7.x) and same issue. This version should work with my hardware so I'm very confused on why this is happening.
