Easiest Upgrade EVER!!!
Just got this refurb MBP and found that the 4GB of standard RAM were predictably and obviously not enough... It should be screamingly fast with 16GB of lovely Crucial memory.
Some of the screws were a little fidgety coming out and going back in - it's why it took me an extra 10-15 mins. to complete. Probably b/c this particular computer, though in excellent condition, has probably been opened several times.
Yes, swap the screws around till you find the perfect fit. Don't force them.
Also (I keep trying to save this as "helpful tool" and it won't let me!)... best tool instead of a spudger? Long girlie fingernails... ;-)
