Thanks for the answers. Well I am sure my Pentium D supports 64-bits. I think the problem resides somewhere in other aspects of its architecture, in combination (maybe) with a BIOS that needs to be "replaced". First, I will buy an alternative, more compatible processor, a Core 2 Duo. If I succeed installing Mountain Lion with this new feature, I will tell you. If so, it means the problem is the old processor and we can be sure that pentium D 935 can't support Mountain Lion, and people with a processor like my own don't need to waste time trying to install it.

Hi, I am trying to install install OS X 10.8 Mountain Lion bootable USB, and using Wait=Yes i can see it stops at System/Library/Extension/TMSafety.kext/Contents/MacOs then a black screen appears and it doesn't change. I already used TransMac to remove all ATI, AppleIntelHD, AppleIntelSNB, and NVDA kexts and tried to write many comands such as GraphicsEnabler=No, -f, -x, -s My components: Intel Pentium D 935 CPU 3.20GHz Mainboard: ASUS P5B-Deluxe P965/G965 RAM: Kingston PC2-6400 CL6 DDR2 2047MB GPU: NVIDIA GeForce 7600 GT 256MB HD: 250GB (I had Windows XP and I formated my HD with Gparted to HFS+, its cleaned now) BIOS: Version 0711, Date 09/29/2006 (in the BIOS menu I set my SATA HD as AHCI in stead of IDE) Can anyone help me finding the problem? How can i solve this? I am a little sceptic that my Processor can't handle this installation...
