Very sorry for this late reply on your last post but thank you, now i understand !

Why did you choose profile MacPro 5.1? It didn't work for me. As far as I know, the only Mac Pro profile that works is 3.1.

Ops someone beat me to this. Reinstall with 3.1 and you'll be fine probably.

To be honest,

Choosing the right mac profile in Multibeast always puzzled me.
I just couldn't find a clear explanation about the different mac profiles and what to choose best for my HT.
So i just choose 5.1 cause it's the highest in ranking (or so, whatever .. :0)

I will try macpro 3,1 or imac 12,2 and see if it performs better.

Sorry, i am still quite a noob in this stuff.
I just don't have the time to sort this kind of stuff out thoroughly.
So i am very grateful to all the people in this community that are so kind to help me out with my issues / questions !

iMac 12.2 works well also, I just heard 3.1 had more C states, but that may not be true. If you have a 2500/2600 CPU and and 6850, then the iMac 12.2 is almost identical hardware wise. If you seeing the hd3000 graphics then use macmini5.1.

I'm having a similar problem, I just built a new PC and am trying to install mountain lion and when it starts to load the installer, I get the grey screen that says "You must restart your computer by holding down the power button" I can't seem to get past that screen.

I ran the -v and it says:



Please help!

Thanks
