Is anyone running a Yosemite beta on a 2009 MBP? If it works great then I'll probably hang onto it. I'm out of space on mine and wondering if I should upgrade the SSD for about $200 or just put the money toward a new Mac. My wife uses this machine for iPhoto and web -- that's about it. It serves as home base for all of our photos and video. So I guess I'm already talking myself out of a new Mac, but I'd hate to upgrade it and then have trouble with the new Photos app next year. What would you guys do?
