I had an Apple on-site support engineer open up a 16” MBP on my kitchen table a couple of weeks ago to replace a cracked screen, and he brought only a small tool roll, a headlamp, and a anti-static work surface and wrist-strap. Took him only a few minutes to strip it down, longer to rebuild and recommission for use.

I must add, I peeked over his shoulder a few times, and my comment that it looks as good inside as it does out was answered with “yes, it’s like being asked to restore a work of art”.

I was just trying to make a joke. I've actually been very happy with working on my MBP, it was easier to re-paste than a Dell XPS from the same year. The interior of Macbooks I've seen have been laid out remarkably well.

Yes, nearly impossible... unless you spend $5 at Amazon on a screwdriver in which case it’s trivial.
