Hello fellow mac enthusiasts! I am the proud owner of a 2007 White Core 2 Duo macbook.. Had it since boxing day '07! I love it. It was my first laptop and as a 18 year old today i still cherish the damn thing almost 7 years later, because its always worked for me and I've had very minimal issues with it. Since new, I've already put in some upgrades into it. Here is what it was stock and to the right the upgrades: Macbook 2007 White model identifier 3,1 Core 2 Duo @ 2.2ghz 1GB DDR2 ram------------------->4gb DDR2 RAm 120gb HDD----------------------->750GB seagate barracuda Hard drive Leopard (10.5.8)-----------------> Dual boot Snow leopard & Win 7 Here is what i would like to know.. Is it worth my time and money to upgrade this machine to the last OS apple says it can run, that being osx lion 10.7 or is 10.8 or 10.9 able to run on it? I hear people talking about installing maverick and mountain lion on "unsupported macs" I currently use the machine for school, in my last year of highschool and would like to take it to university with me..... as i still get about 2 hours on the battery. (battery health 58 according to istat pro. ) I mainly use office, garageband, Flash, Photoshop and illustrator. But do i need the upgrade? i had to upgrade it to Snow leopard last year cause apple pulled the plug on leopard. But i've heard that lion isn't that great and that its "apples vista" (not my opinion, just what ive been hearing) and would just like to know if my machine will handle it.. im comfortable about running fine but my GPU. Its only the intel GMA X3100 144mb Vram. Thats the only reason apple cut this machine at 10.7 according to toms hardware and apple.ca. The macbook pro using the same CPU but better GPU can run maverick. Apparently. So mainly wanna know.. do i need this $20 lion upgrade just yet, will it run decently on my laptop given i cant afford a new one i wanna stretch this ones life and is Lion actually that bad as its portrayed or is it just another example of false information. Please let me know your opinion. Thank you.
