hey all, my first post. MacBook late 2008 unibody 5,1. I've settled on Mojave, I just like it better. anyway, i tried the apfs rom patcher, picked the correct chip # (I thought, took it off of chip on logic board), and patched. All seemed to go good and I continued using after rom flash. then when I had to reboot, all I get are the s.o.s. beeps. I'm guessing it hosed the logic board even though I triple checked the chip #. Am I SOL?
Join the club! Bricked a Mini3,1 with the dreaded APFS ROM Patcher by being impatient, killing the Patcher after 43 minutes S/B 45 minutes, at least, btw. There are a plethora of MCP79 variations in EEPROM to sort out, apparently. Pulled the HDD from the "SOS" Mini and noticed files written by the Patcher - so, completion may have been near?
APFS ROM Patcher and MCP79, nope. Too much risk per dosdude1.
Now, read about those who got it to work. ?
