My config :
-Gigabyte Z68XP-UD3
-Intel core i5
-ATI Radeon 6870
-8 gigas Ram
-SSD 64 gigas​

Classical Bios Options : Enable AHCI...

Yosemite USB key
-Download Yosemite from App Store.
-Use UniBeast to create key with legacy support (series 6 motherboard).

Installing Yosémite on the SSD (upgrade from Maverick).

Rebooted from the USB key (F12) and chose my SSD with boot flag "cpus=1"...
In my case, impossible to boot on my SSD without this flag... (kernel panic) even using -x -v -f....

Ran MultiBeast with UserDSDT (DSDT.aml F8 on the desktop).
-Realtek 8111-ALC 889
-TrimEnabler
-USB 3 support.
-AppleACPIPlatform Rollback.
Rebooted directly on my SSD with the same flag : cpus=1 : everything OK... Rebooted then on the SSD without any flag : whole success : everything is working...:)
 
Gigabyte Z68XP-UD3 Succes

This is not really a success because you are only using 1 of your 4 cores. That doesn't work mate.

What makes you say that? His last sentence says he booted successfully from the hard drive with no flags needed.
 
No read carefully mate. He still needs a flag.
 
Can anyone explain step by step how to install Yosemite 10.10.1 on Gigabyte Z68XP-UD3 ?
I am currently running 10.7.3 and I tried without success to upgrade to 10.10.1
I read and followed all the guides and forums, still no luck. All goes well till I run MultiBeast 7.1.1 and restart. tried all the flags possible.:banghead:

Please help
