Unibeast and OS X 10.8.2 Oddities

[miramar]

I've come across a problem with OS X 10.8.2 and Unibeast 1.5.3. Seems that something has changed in 10.8.2 to cause this as the problem does not occur with 10.8.1

Symptom
Booting off Unibeast 1.5.3/10.8.2 USB, you see a cursor then beachball on a grey screen. This happens just before the language selection screen which never appears.

Workarounds

• Disable VT-d in BIOS or
• Boot Unibeast USB with -x (I avoid this as I'm unsure if it will adversely affect installation) or
• Use Unibeast 1.5.3/10.8.1

Notes

1. Language selection screen takes longer, up to 30 secs, to appear than 10.8.1 so be patient.
2. It's related to VT-d in BIOS/CPU. VT-d must be disabled
3. Occurs only with CPUs that supports VT-d so you would not see this problem if you're using e.g. a 3570k.
4. I've only observed this on 2 motherboards: GA-B75M-D3V and Zotac Z77ITX-A-E
5. Z77ITX-A-E/3770k (no VT-d setting in BIOS): 1.5.3/10.8.2: OK, 1.5.3/10.8.1: OK
6. GA-B75M-D3V/3770 (VT-d enabled): 1.5.3/10.8.2: Beachball, 1.5.3/10.8.1: OK
7. GA-B75M-D3V/3770 (VT-d disabled): 1.5.3/10.8.2: OK, 1.5.3/10.8.1: OK

*Also applies if you have upgraded from a working 10.8.1 installation to 10.8.2.

YOU ARE THE BEST !!!




Gygabyte GA-H55M-S2 + Core I3-540 with retail 10.7.5 + Chimera 1.11.1

try Mountain Lion 10.8 and 10.8.1 : OK

try Mountain Lion 10.8.2 : beachball !!

Read this topic and disabled option Virtualization Technology (not VT-d)

Reboot with 10.8.2 : Language selection screen appears.

Good.

Thank you!

I can confirm this worked on a Gigabyte GA-Z77X-D3H.
