I've sorted my affairs out. I have a keypassX database and master passwords listed my will.
I take it you read the rest of my last post -- I have dealt with this.
Most people amble through life and never ask the question "what if?". If they do ask it, they light another cigarette rather than put mitigation in place. That is naivety and people need to snap out of it, pretty damn quick. The world is a big and complicated place and if you don't want to leave a pile of pain and suffering for people if you do decide to walk in front of a train or something then you need to sort it out.
No excuses.
Sorry.
As for Apple, they have no obligation to do anything. The device is an asset (tangible) and the will probably states about transferring them and the contract and terms are with the person who signed it. In this circumstance, they will cause themselves problems if they act and say yes here you go or no chance. I'm sure the Apple Account which is the issue wasn't even mentioned in the will or signatory's asset declaration.
Doomed either way.
Apple chose the right answer: mu (i.e. no answer).
