Hello! I am looking to run OSX86 on an old laptop I used during school, which barely gets any use from me anymore. I am looking to mainly run XCode on it for iOS development and that would be the most resource depending thing I plan on. Its been a while since I have done this so any help you could provide would be greatly appreciated. The laptop is an HP Compaq NW8440 with the following specs: Intel Core™ Duo T2600 2.16 GHz processor 1024 MB 667 MHz DDRII SDRAM -- WILLING TO UGPRADE 15.4-inch wide WUXGA display ATI Mobility Fire GL VL 5200I was wondering if anyone could point me in the direction of the latest version of OSX that I could run on this system? Also is there any preferred method of install these days? I have no problem plugging a keyboard/mouse into the laptop if the trackpad drivers don't work correctly, but was wondering if anyone could provide some insight. As always your help is greatly appreciated - thank you in advance!
