I was at a buddy's place earlier today. He buys and sells older Macs often. We were going through two MacBook Pro (15-inch, 2017) models of the same spec.

On one of them, we downloaded the latest version of the "Install macOS Ventura" app and ran the startosinstall command buried inside said app, with the --eraseinstall and --agreetolicense flags. (The latter flag wasn't necessary, but I thought it useful to call attention to that one for him since it makes the operation easily scriptable for Intel Macs and since he's trying to break into the world of IT.) The machine, per the --eraseinstall flag, does a wipe and reinstall to Ventura (it was on Mojave beforehand) and all of that seems to go normally.

However, on the other end of that installation, the keyboard completely died. Not just one or two keys being stuck, or pressing funny, or double-pressing, or any of the usual problems that plague the keys on this keyboard. It just altogether died. Startup modifier keys (e.g. Pressing and holding "Option" or "Command+R" or anything of the like) did not work. The keyboard seemed to be unresponsive both before and after booting into the operating system.

Now, I've heard of the butterfly keyboards failing mechanically due to poor design. But I don't believe I've heard of the entire keyboard suddenly failing all at once after an OS install, let alone via a wipe-and-upgrade/reinstall using the startosinstall command (which I've used a TON of times in professional settings). Could it be a byproduct of (a buggy update of) whatever UEFI firmware update that happened in the process of installing Ventura? That's the only thing I can possibly think of that would explain it working before the wipe and reinstall, but not after. I mean, I had to use the keyboard to type out the command being used!

Has anyone ever experienced anything like this on their Butterfly keyboard on any of the MacBook Pros (or MacBook Airs, for that matter) that had them? Or am I right in that this seems out of the ordinary, even for the likes of the Butterfly keyboard?

Plug in an external keyboard.
Now do a proper "erase and install" with no funny business like you tried above.
See if that fixes things.

You do know that is a supported method of erase and install, right?

Like, that is literally designed by Apple to allow enterprise admins to perform erase and install installations remotely and/or as an alternative to using Internet Recovery.

I'm not sure what you think installing it via more pedestrian methods that are no more supported than the one I tried above will actually accomplish.

Also, entirely irrelevant to my questions of "does this keyboard ever fail all at once?".

That's definitely out of the ordinary. Something else is going on.

The complaints about the butterfly keyboard almost always fell under mechanical issues like keys getting stuck, keys double pressing, or only registering if you hit it a certain way. I don't remember any being about total keyboard failure.

Also, there's nothing about the butterfly mechanism that should make electrical failure more likely because it's not actually a switch. It's a stabilizer. The underlying dome switches that complete electrical circuits to transmit keypresses look to be much the same dome switches from Apple laptops of other eras. The butterfly mechanism was exciting for all the wrong reasons, but the electronics sitting underneath them were totally routine.

Do you have a USB keyboard to test with? If so, does it work?

We didn't have time. I left before that could be attempted. Incidentally, I'll be back over there within the next twelve hours and can report back on whether or not that changes anything.

That was kind of my thinking as well. I'm leaning more towards the UEFI update that would've occurred during the Ventura installation being the culprit.

So, completely anti-climactic conclusion to this story: It just started working without a wipe. I believe my friend will look to get rid of it as soon as possible.
