Will try when I get home, however I feel like I did that yesterday several times. At any rate, thank you for the response!

Please be patient. My Mac was out for repair and in typical fashion Apple has formatted it (for no reason). I need to get up and running before I can do anything. I just collected the laptop and am on my way back home. I won’t be giving out any test scripts now or in the future - so no point asking.

Sorry to hear they wiped your drive. I wonder how often they decide to replace the entire bottom half when there's major component replacement taking place. I had two keyboard replacements done on 2016 15" MacBook Pro. The first time hard drive was wiped or full bottom half replaced when it was sent out to the repair facility. The second time the hard drive stayed intact when the work was done at the store. The top case with new keyboard, trackpad, and battery was the only new component.

@itsage only the top case was replaced so a format was unnecessary. Maybe they did it because system was running beta OS and it was flagged in their internal diagnostics.

I suppose apple is keeping the bad habit of wiping its customer data for security and liability reasons, during the "repair" process.
You don't want an apple random insider begin leaking customer data extracted with the same apple code and tools.
It would be a disaster that can't be easily defended in court even by the best lawyer assault team apple dispose.

Then they should do it consistently for all repairs (they don’t). Funnily enough my Windows disk is still present so they only wiped the macOS partition.

Apple can’t access your data if your disk has FileVault enabled (XTS-AES-128 encryption with a 256-bit key) - which is the default macOS configuration these days (on T2 Macs this is always enabled, with the option of disabling the password - in a sense, at rest the disk is encrypted regardless). The only thing they can do is erase the drive. In my case they should not have erased it as they just moved the entire board to a new top case (that has new battery and trackpad). Well, at least I got the replacement for free (problem was swollen battery) even though I was out of warranty so I’m not complaining too much - just nitpicking.

You are right not every time the disk is erased, wonder what trigger the disk cleaning procedure, if a specific hardware replacement have to be done for example.
[Edit: yeah in fact the drive is wiped before the machine quit the apple secure environment to reach the 3rd party refurbishing sites]

I suppose that FileVault is similar to the other high end data encryption tools, however often even the most secure tools come with some sort of recovery console.
So i would suppose that apple can actually recover user data from encrypted disks, now if apple did not comply it is another story.
I mean, i have to admit, it is a common practice in the IT field, the data remain encrypted once the unlocking key is wiped out and can only be recovered.
One can only overwrite the existing blocks with new encrypted information, pretty simple and enough secure solution .

Yes there is a recovery mechanism but it is not possible without recovery key which you can recover from iCloud if you opt in (which Apple cannot get without Apple ID login - so only the user can do it). If the recovery key is also unavailable, then the disk is unrecoverable by virtue of reversing or brute-forcing the XTS-AES key being computationally infeasible. Thus there are only two keys: your password and a created recovery key (which can optionally be secured by iCloud), that can unlock the disk. You can read the T2 documentation which gives more insight into when data is considered lost - one example is too many password attempts (it’s a very high number, but there is a cap), which completely disables T2/storage - rendering all data inaccessible permanently.
