I have run OCLP before, going from Monterey to Ventura on my Macbook Pro Retina 2015. I upgraded the SSD, installed Monterey, then run OCLP to upgrade to Sonoma to give it a try. The install went fine, and I was running Sonoma with no problems. A day or so later, my macbook froze up so I turned it off & on again. It would not boot up. I rebooted with the OCLP USB, went into disk utility and thought I'd wipe it all and start again, but the whole drive would not show up, only a drive of about 13gb. I tried booting back into OCLP EFI, but still nothing, just a black screen. I tried going to the Mac OS installer drive, but I got the no start up disk with a question mark. I then even tried using the Monterey install USB, but Disk Utility wouldn't show the whole drive, same as last time. I feel I've now wasted a new SSD and cannot recover it. I can't find an enclosure for a decent price that fits the Mac proprietary drive to try and wipe it. Anyone got any ideas or suggestions what I can do?
