Hey guys, So I'm think about updating my macbook pro to 10.9 from 10.6.8 and I'm super apprehensive about doing so. I've heard a lot of the bads, and not so much of the good. My macbook pro is from 2010 with 4GB of RAM and pleeeeenty of free space. I use this computer for work (mostly use adobe programs photoshop, illustrator, and indesign) and am worried about performance issues. Any advice on the issue?
