Hey! So my 2012 MBP throws a fit when I try to use aperture. Here is a readout from activity monitor: VM size: 288.31 GB Page ins: 15.45 GB Page outs: 12.13 GBs Swap used: 5.14 GB I CLEARLY have a RAM problem (presently 4 GB installed). I know the official capacity is 8GB, but I've heard 16 GB also works. My question is: will I be OK with 8GB or should I go for 16 GB? Also, does upgrading RAM in this machine invalidate Apple Care? I'm only under 1 year right now anyway but if I try to re-sell the computer this would be good to know. Just bought the 27" iMac so waiting for the next round of Air/MBP retina to come out and then selling this for one of those. Thanks!
