I just got my new Mac Pro 2.66Ghz (4gig RAM), and would like to try to attempt to go through the rEFIt and vmx-var-set.efi steps (in this thread: http://forum.parallels.com/thread3273.html )to get VT-x enabled. I realize some folks got it working, some did not. I have upgraded my firmware using EFI 1.0 firmware upgrade, and also am running 10.4.8.
Two questions:
- Does anyone who has done the EFI 1.0 firmware update and that is running 10.4.8 on their Mac Pro gone through these steps, and have VT-x working, w/o then having to do the sleep trick anymore?
- Are there any risks to attempting these steps? Risks meaning hosing the EFI firmware or something else serious?
