Apple uses TPM-like hardware for their encryption as well - and that's what the OP was asking about. The same solution.

They actually don't; not for Macs anyway - although that might be different for the models with TouchID. FileVault on the Mac is entirely software-based.

[izacus]

Yeah, on touchbar MPBs they store keys in the TouchID coprocessor which does the same as TPM on other machines.

Do they escrow across reboots? I know they don't on iOS.
