This was an excellent guide. Very detailed and comprehensive.
Brilliant solution from Sotiris Alexandridis! This is a critical fail on the part of Apple. I know no one with a 2013 machine without broken caps.
M5 flat washers can be hard to source. I found SAE #10 brass flat washers (a Home Depot item) are the perfect fit. They have a smaller o.d. than #10 steel flat washers.
Set these two screws in a special place. I use a loop of masking tape on my workdesk. They heads appear identical but the size and thread are very different to all other screws in this procedure. Trying to use one of the other similar-appearing screws will be annoying if not damaging to its threads.
The two 2.5mm screws circled in orange are close to impossible to put back in due to the deep inset of their mounting tabs. Either use the tiniest dab of grease to adhere them to the tip of your 000 Phillips driver or magnetize the screwdriver.
I’ve done a few of these and it should be noted this connector is a very firm fit. Using the flat end of the spudger to pry alternately at the protruding sides can be helpful.
The guide should be edited for tool list so users don't gather the wrong tools. The phillips driver needed is #0, not #00.
The comment about "Step 13 not being required and shouldn't be attempted" is incorrect!
