If you had enabled Find My Mac on a T2 equipped mac, factory reset WON'T unlock the device.

However, since Apple actually had full authority and cryptographic ownership of the chip, they can generate a key given serial number which will reset T2 contents.

Personally, I think the setup should be that you don't have to go to apple for it, but it should immediately wipe device identity and disk encryption then (and the disk should always be encrypted)

I don’t think that’s true, I’ve never had to do that, and this is not a part of Apple’s documented reset process for resale of a machine. If you are the device’s actual owner and you use the simple process Apple outlines, it will reset it for a new owner, period.

At the time I bought, the documented process included "manually disassociate FMM from the device in iCloud settings"... except it wasn't well propagated information and the previous owner and reseller just tried factory reset.

Been there, went with Apple support over it, the only reason I still don't have it unlocked is because I didn't have time or energy to redo the whole setup. Might redo the apple-driven unlock process, but the hw is not worth it really.

EDIT: Apparently the nice simpler procedure that does wipe FMM only arrived in Monterey.

"Erase All Contents and Settings" is the only button you need to push on a T2 (or later) Mac, and it is the factory reset button. It will unlock the device.

Your information is outdated.

I have physical proof on my hands. It's possible that they fixed it in later version of the OS, but factory reset is what the reseller did with previous owner, and it did not wipe FMM registration, leaving the laptop half-stuck in terms of ownership - I only figured it out trying to register FMM to myself.

I assume things were harder in older versions of macOS, but you can read step 2 yourself: https://support.apple.com/en-us/HT201065

Any T2 Mac or newer requires only that button to be pressed, and then click through the wizard to complete the process.

"Other ways to disable Activation Lock"

"Activation Lock is disabled when you use the Erase All Content and Settings feature."

which confirms the same thing. The experience that people have is very simple these days.

Yeah, this was fixed, supposedly, on Monterey.

Which still leaves considerable amount of laptops with broken FMM registrations in T2. Especially since it was upgrading to Catalina, iirc, that started problems.

That's not the case though, they are finding. A person like you or me might follow the process correctly, but a company going bankrupt or aging out old equipment doesn't care nor have any incentive to properly unlock their machines before shipping to a recycler. Thus contributing to massive waste.

> but a company going bankrupt or aging out old equipment doesn't care nor have any incentive to properly unlock

This is not true. The bankruptcy process attempts to recover as much value from assets as possible, and so creditors and the process should absolutely care to properly unlock in order to extract maximum value.

Similarly, aging out old equipment is still sold to make money, and unlocking should achieve more resale value.

The incentives are absolutely there. And the article does absolutely zero investigation as to where exactly there's a breakdown in incentives or communication, or if it's even a major issue at all. Maybe the process is working 99% of the time.

The user who refused to unlock it before selling and/or the purchaser who did not check that it was unlocked before purchasing are the ones contributing to massive waste here, not Apple.

only due to the systemic waste apple has created by designing the system in this way

When that user has died or otherwise doesn't exist, then it's hard to blame them. The only remaining thread of blame leads to Apple.

Unless this is what's happening in the majority of cases I don't think it's fair to focus on it. My hunch is that most of the laptops in that article are either stolen or dumped by users/corps who couldn't be bothered to unlock them.

Recyclers will quickly find that they should not accept the machines unless the seller has unlucked them.

If bankcrupt, the original company may have a duty to unlock them because they will be worth more.
