OS X 10.8 (Mountain Lion) Won't Support Some 64-bit Macs With Older GPUs
MojoKid writes "Apple is pitching Mac OS X 10.8 (Mountain Lion) as the cat's meow, with over 200 new features 'that add up to an amazing Mac experience' — but that only applies if you're rocking a compatible system. Some older Mac models, including ones that are 64-bit capable, aren't invited to the Mountain Lion party, and it's likely because of the GPU. It's being reported (unofficially) that an updated graphics architecture intended to smooth out performance in OS X's graphics subsystem is the underlying issue. It's no coincidence, then, that the unsupported GPUs happen to be ones that were fairly common back before 64-bit support became mainstream."
And this is why Mac OSX doesn't cost just $19.99. If you bought a Mac in 2011, you've already subsidized your purchase of OSX Mountain Lion you'll buy later in the year. Problem is, if you bought a Mac in 2008, you've already used up your copies of OSX, so you don't get to buy Mountain Lion at $19.99. Apple's decided you need to buy a new Mac to subsidize the next 4 versions of OSX, which you'll be free to buy for $19.99 of course. Until 2016 of course when the process starts over again.
I have a macpro1,1 with 8 cores(clovertown), 16 gigs ram, and the current 2011 ATI video card.
Yes I have had the machine for 6 years and I could upgrade. But the current hardware is not that much of a performance upgrade for the cost.
Xeon based systems of this generation like the Dell 2900, 1950, are still a viable system and still well supported and will be for years into the future.
Apple decided to stop supporting this machine a few years back by not allowing it to run a 64 bit kernel with the lame excuse that a 32bit boot loader can not boot a 64 bit os.
Solution that works great.
Hackintosh your machintosh.
Install cameleon and boot the mac in legacy mode as a hackintosh. With Snow Leopard, the machine runs the 64 bit kernel and is noticeably faster. There is no reason that Mountain Lion will not work well also since the macpro1,1 is the same hardware as the 2,1 and most of the 3,1.
By doing this you can now run any video card that you want and still maintain a legal right to use the software.
I was starting to decide on upgrading to a current mac pro, but to be honest, there is no reason to drop that kind of change on a machine that Apple will drop within a 5 year period.
I've just dropped a 256gb SSD in a thinkpad from 2006. The thing runs better than when it was brand new and it runs considerably cooler and quieter. It's for development and non-gaming entertainment so even if is no doubt lacking in the gaming department that doesn't matter.
I intended to keep my macbook until it falls apart or the battery dies. There's no need to buy new hardware just for the sake of it if you don't need it. Unless you buy rubbish low-end Dells or Acers which then you'll be lucky to get 3 years out of it.
