I have a Late 2007 Macbook, core 2 duo 2.0, 2gb ram and 250gb Harddrive. I am still running leopard, and am getting frustrated with the lack of support from app (like chrome). It is running very slow and hot, I also need more storage space. I have a 320gb external drive that I could swap in fixing the storage issue and then do a clean install (buying snow leopard) and upgrade to Mavericks but according to the apple site my computer is not compatible with the new OS, can anyone confirm this? I do not want to spend the time and money to be in the same place I am now when snow leopard drops support like soon. I mainly use the computer for web, light office work and music/photos with the occasional netflix stream. I am also considering an upgrade to a 2011 15" pro with high-res and anti glare, as I hate my screen. I am not interested in the new retinas as I would have to spend almost $2000 for enough storage and I want a matte screen. Is the OS upgrade worth it or should I just buy a new machine?
