Would also add that one of the ram guard screws went awol for a while after flying out of my tweezers. I guess it wouldn’t really have mattered to lose one screw but finding it, after several minutes of searching, was a relief.

Agree with the comments re rubber guards. Also, fitting the new memory into the clips is not that straightforward either. Being used to just slotting memory into main motherboards this, by comparison, was rather fiddly and frustrating. Sorted in the end though but I have yet to test!

I have only ever cursed Apple a couple of times (as opposed to the several million times for Microsoft!), and this was one of them. That damned antenna screw, putting it back in was a trial of patience and perseverance.
