Yosemite on Gigabyte GA-B75M

This post describes the steps to install Os X Yosemite on my system, described here.

My system had already Mavericks installed, so I received the notification to upgrade the system to Yosemite. I started it, using the default Apple procedure, just to download the app image. Once downloaded, I stopped the installation. I intended to do in any case a clean installation, so I didn't even check the possibility of doing an upgrade instead of a from-scratch installation.

After having the Yosemite installation app, I downloaded UniBeast 5.0.2. I used the same BIOS settings already used in Mavericks: default ones, ensuring that XHCI and EHCI handoff are enabled, and VT is also enabled, but VT-D must be disabled.

After installation, it is needed to start Multibeast 7.0.2 to fix the correct drivers. The correct installation for my system requires:

  • Quick Start: select DSDT free
  • Drivers:
    • Audio: add ALC887/888b current
    • Disk: add 10.10 TRIM patch ( 3rd party SATA already selected )
    • Graphics: nothing
    • Misc: no changes (FakeSMC already selected)
    • Network: Realtek: add RTL81xx
    • System: no changes (nothing selected)
  • Bootloaders: Chimera (already selected)
  • Customize: No changes, already selected:
    • Basic Boot options
    • Generate CPU states
    • Hibernate mode -desktop
    • Kext dev Mode (needed to use unsigned kexts)
    • Use kernel cache

Checking the logs, I saw that even the AppleHDA assertions displayed on Mavericks were gone. really a flawless go!
