In 2007 Apple stated to its consumers the Mac Pro was 100% 64-bit edition Steve Jobs himself use the words OS X 10.5 Leopard is 100% 64-bit you can still watch the keynote. Facts are this many people myself included believed when Apple compared their Mac Pro so famously against a Dell workstation they advertised the Mac Pro came out the better price and because of Boot Camp was 100% equal to the Dell workstation now tell me this can you run any version Windows in 64-bit on a 2006 or 2007 Mac Pro? answer is no you cannot so really people like me that use both OS X and Win programs were not told about Vista not being able to run 64-bit until our machines were least one year old. Now tell me this was their difference yes there is a Dell is not limited by an EFI to only run 32-bit operating systems outside of OSx don’t tell me you care about only Mac programs are not talking about you I’m talking about why I bought it and feel it is not 100% 64-bit. Apple lied

I bought CS5 Master Collection JUST so I could have After Effects CS5 for school. I have a mac mini w/snow leopard that I can NOT get to boot with 64 bit capability. I need help. I did the 6 and the 4 hold down which some of you say worked for you. No go here. Can anyone help me please?? I spent alot of money and would’ve just stayed with CS4 if I knew about this hassle before hand. Seems like SOMEBODY at Adobe coulda mentioned this problem….

If you have a Mac and you wanna check if you can use 64-bit type this command in Terminal: ioreg -l -p IODeviceTree | grep firmware-abi if it returns “firmware-abi” = <”EFI64″>" you will be able to boot with 64-bit Kernel and Extension (just checkout http://blog.leanopen.com/2010/04/23/doesnt-your...) if it return <"EFI32"> you can't do this trick.

Yes, I just got the 2.4GHz unibody style Mini and it will boot the 64 bit kernel if you hold the 6 and 4 keys while it boots, I didn't expect it to but tried it anyway and it sure did.

If you boot into a 64bit kernel, none of your 32bit device drivers will work, so people who are upgrading will struggle.

I saw that article mentioning how the last Mac mini was not able to be 64 bit with Snow Leopard. Can the 2010 Mac mini do this I wonder?

Sue them! That's a great idea. You probably walk around looking for people and companies to sue.

if you have 64bit EFI it can be done with a bit of hacking around.

I am surprised that Apple doesn't support Snow Leopard Server in full 64 bit mode on the Mini, since Apple is bundling the two. Servers, especially when juggling big databases or render apps, would seem to be the sweet spot for 64 bit apps, no?

There shouldn't be software compatibility issues, as most apps running on a server will be the same as on the mini's big brothers; there's been plenty of time (and a couple of recent updates) to tweak the hardware if necessary; and the server has enough CPU moxie that one might very well want the extra security and anti-obsolescence of 64 bits.

This suggests that a 64 bit kernel is less of a big deal than some make it to be.

64 bit applications would only run as 32 bit applications on a non-64 bit kernel. It's impossible to run 64 bit instructions without a 64 bit kernel…
