Hi there, I just thought I'd pop in and ask a few questions and hoping they get answered in regards of upgrading my RAM. I'm considering buying 8GB RAM to install instead of 4GB's, I'm a Graphic Designer so I'm constantly using Photoshop, Illustrator, InDesign and so on and it gets really laggy and sluggish with them all open. I was just wondering if buying the extra memory would help speed up my laptop? Looking at my page ins and outs I have 1.91GB ins and 3MB outs with Finder, Chrome, Spotify, Photoshop and Illustrator running. I'm not too familiar with the technical side but I assume that's not amazing? Oh, and around 15-25mbs free... But it also says I have 1GB inactive. Is there a way to fix it up? MacBook Pro Mid 2009 15", 2.53GHz, 10.7.5, 4GB RAM Thanks heaps!
