遗产：爷爷留下了一台未清除数据的MacBook Air, 但不知道密码，我该如何使用它

My grandfather died recently; he owned a MacBook Air. I want to use it now but it isn't wiped, and he never wrote down his password. Can Apple help?Phillip Remaker, Apple Fanboy since 1979Updated Dec 19First of all, understand this is completely different from the FBI situation. The FBI wanted access to encrypted data. Apple literally can not do that. The macOS and iOS systems are designed to protect encrypted data from all unauthorized viewers, including Apple. If you want the data on the MacBook Air and the disk is encrypted, Apple cannot help. It’s just technically impossible, unless you find your grandfather’s printed out iCloud recovery key[1].If you just want to erase the machine and start fresh, there are options.If the machine is not iCloud locked, you can simply reinstall the operating system. If you boot into recovery mode or Internet recovery mode, you can erase the disk and start fresh.If the machine is iCloud locked, you will need to get it unlocked to reinstall the operating system. This is intentionally difficult, to prevent thieves from unlocking stolen devices, but it may be possible. If you have access to his email, just reset his iCloud password at iforgot.apple.com. If not, Call Apple. They will walk you through a process to identify yourself as a legitimate owner and remove the iCloud lock.The device cannot be unlocked in a way that accesses encrypted data, but it can be unlocked to create a usable freshly installed device for an heir.
