We have got an inquiry for a NAND-recovery on this Macbook, but we have no experience for Apple's stuff so we are going to send the customer to another -- bigger -- DR-house. However, this doesn't stop me from learning something new
Since it's Apple, my first thought is that their NAND-protocol is a proprietary one, and probably even encrypted. So not simply a chip-off recovery by pulling the NAND and dump it. Do they (Apple) use their own controllers, or do they use standard ones? For encrypted drives, is there even a single chance for recovery, or is it the nowadays standard "bad luck, you should have backed up your data"?
