Recovering data and reinstall Catalina on a MacBook 2012 after failed Sequoia installation attempt
MacBook late 2012. 2.3 ghz quad 4 i7 processor, 16GB RAM, 1TB. SSD.
I got Time Machine back ups.
I was watching YouTube and came across how “easy with the new GUI to trick your MacBook (or other way) installing Sequoia on a MacBook 2012. Cool! I’m relatively familiar with Mac, I am in terminal quite a lot, i think I got this.
I tried. I failed. It won’t even restore from Time Machine or a new install.
what it will do is vomit code 24/7 if I let it.
I am guessing, I mistakenly chose a setting in their mistake proof GUI that fragged whatever Mac calls its bios. I’ll attach a screenshot of some of code it just spews out.
in order now:
- attempted to install sequoia on MacBook 12 using open source
- rebooted on install from usb to recovery 20 times
- Tried repairing the drives repaired said A-ok.
- restarted once in safe mode
- restarted. back to recovery.
- frag this. I’m going back to catalina. Stick in my time machine drive and attempted to reinstall.
- took all night and spewed code all night.
- back to recovery.
- tried reinstalling OS FRESH.
- Another all nighter of spewing code aaaand back to recovery.
- I went and bought a Mac mini m2. 16GB ram and 512GB SSD.
- still need my MacBooks timemachine that apparently I can’t retrieve unless it’s installed. Lovely.
- Help? I tried ahem EVERY way possible of getting an install of Catalina I can put on a flash drive and attempted that but I dunno. Is there a way to flash Mac’s version of the bios if indeed that’s what’s messed up?
sorry for the length. This has become my second and third job and new obsession and I hate it a lot.
