Regarding the Apple's FileVault bit, are you referring to the recently disclosed Intel vulnerability ( https://www.theregister.co.uk/2020/03/05/unfixable_intel_csm... ). Did FileVault ever use this Intel feature (even on non-T2 Macs)? It seems that there is some contention on Twitter whether FileVault is affected.

Besides that... “completely useless?” Is that right? The only way you make disk encryption totally useless is by breaking the crypto. This allows an evil maid attack at best... a very different vector for most people than “completely useless”.
