Problem after 1 month of use... not booting anymore

Hey everyone,

About a month ago, I updated my MacBook Pro 13" (2016) to Open Core Legacy. Everything seemed fine until about a week ago when the Mac started shutting down on its own. Since the day before yesterday, the Mac won't turn on at all and it always gets stuck at the loading bar (see Picture 1).

I've tried various things:

  • Attempting to reopen via the EFTI Boot = Failed
  • Restoring from an old backup = Failed
  • Re-downloading macOS = Failed

What else can I do? Or have I missed something?

I have searched this group but didn't find the right answer... if there has already been a post about this topic, please link it here.

Thanks in advance for any help!
