I'm looking for the performance bottleneck on my late-2011 MBP, and am asking for informed advice before I make a move. Indesign CC 2015 takes about 90 seconds to load, but once running is okay. Except if I'm running mini-Bridge, or round-tripping to Photoshop. Spinning beachballs everywhere. Wonder if this a RAM, HD, or processor issue. About 10% page-outs. Late 2011 MBP 13" 2.4 Ghz Intel Core i5 4G RAM 500G SATA HD Thanks.
