Hey guys,
I have a MacBook Pro Retina 15" Mid 2014 running Big Sur on it. Now I tried to update to Sequoia with the OCLP but its not working. So I need some advice or help of you guys if possible. I'm trying for 3 days now, but I'm running out of ideas.
My Mac does not recognise my USB when I reboot while holing down option key.
My ext. drive:
- Kingston XS1000 (1TB)
- Formatted to Mac OS Extended (Journal)
What I already did:
- Disabled SIP
- Deleted NVRAM 3 times
If anyone could help me, that would be awesome!! =)
