Booting the 64-bit kernel on the 2006/2007 Mac Pro

[Corpheus]

I don't know if you aren't understanding me due to a language thing or what.

I have a 1,1 here and I was THRILLED to have a flashed 7950 as it's card.

You get full boot screens, perfect 10.9.1 performance, and a good Windows gaming machine, all in one.

The boot screens make switching OS's painless and worry free.

Right this moment I can hear someone in the office using it for "League of Legends"

A flashed 7950/70 and a 1,1 with Tiamo's boot EFI runs 10.9 just like a 5,1. Yes it is true you could use a GTX780 (better be sure it's an "A") or a Titan or a GTX680 or whatever, but any of those Nvidia options will NEVER have boot screens. The 7950/70 option gives you full, 100% seamless operation.

When 7950/70 first got released for Mac I complained much that the EBC boot screens gave impression that 1,1 had a savior, but lack of 32 bit drivers ruined it. Tiamo fixed the issue . Better than most hacks in most regards. No cost, nearly seamless. Doesn't really get better than this.

You can flash a GTX680 with "EVGA GTX680 Mac Edition"-ROM and you'll have boot screens as well.

Not in a 1,1 you can't.

How do you know that your Mac is running in. I run my Windows 7 partition in 64bit mode, but I don't know if my Mac is doing the same.

How do you know that your Mac is running in 64-bit mode.

Run

Code:

uname -a

in Terminal to see that.
Much easier (or logical) thing is:
- if you're running OS X on your Mac Pro 1,1/2,1 up to 10.7.5 then it's 32 bit
- if you're running Mountain Lion or higher, it's 64 bit (with a help of custom boot.efi).
