I am so confused about Windows 10 and boot camp support for my MP. Apple seems to say I can run the latest OS X El Capitan, but not Windows 10... Is that right? Why not Win 10? Geeze, I'm so confused by the whole thing... I have been so out of the loop, I don't even know if my MP is still worth using with today's applications. My MP was actually born as a 2.66 quad, and I changed the cpu a week after getting it with a 3.33 quad, and I installed the GTX 285 for Mac. I am still running leopard (not snow) and I dual boot into Vista 32 bit... Truthfully, I'm kind of afraid of installing a 64bit OS, thinking that any type of firmware update by Apple will render my leopard install and apps useless? Don't know. All of my work is in leopard and I don't want to break anything, but then again I also don't like using the old stuff... Confused, ugh! Thanks for your help!!!
