I had a 2016 MacBook Professional operating macOS 12 that stopped booting attributable to a corrupted arduous drive. Earlier than it failed, I managed to again up the info quantity, which has been sitting on my exterior HDD for the previous few years.
I not have entry to the e-mail handle related to my iCloud account, however I must get better my iCloud Keychain information.
I perceive that iCloud Keychain retains an area copy that is still accessible even with out an web connection. Nonetheless, in contrast to the usual native keychain, it depends on sure hardware-based checks to operate.
I’ve all of the system particulars from my outdated MacBook—serial quantity, {hardware} UUID, MAC handle, and many others. Would it not be potential to emulate a macOS VM that intently mimics my outdated {hardware} to regain entry to the keychain? My present MacBook is an Intel mannequin, in case that makes a distinction.
I’ve already tried copying every part from the backed-up information quantity into the info quantity of a macOS VM, however the offline copy of the iCloud Keychain doesn’t seem. Every little thing else is there. I examined this on my present MacBook by backing up its information quantity, restoring it, and confirming that the iCloud Keychain remained accessible (with the community disabled to forestall iCloud from syncing, logging out, and eradicating the keychain). This leads me to imagine that the keychain stays obtainable as a result of the {hardware} is identical.
Any recommendation or recommendations could be vastly appreciated!
