If you don't have a nVidia Maxwell graphics card and don't need the nVidia web driver, like I do, then, see
Post #2 in tonymacx86's 10.10.2 announcement.
If you do have a 750, 750 Ti, 960, 970 or 980, then follow this procedure:
Repair Permissions using the Disk Utility on the drive to be updated;*
Backup your current installation using Carbon Copy Cloner or SuperDuper -
Do This;
If your installation's System Definition (SysDef) is not Mac Pro 3,1 (Early 2008 or MP3,1), run MultiBeast for Yosemite (without your .mb file) just changing the SysDef to Mac Pro 3,1 (MP3,1) as the nVidia web drivers won't install otherwise.
Customize -> System Definition -> Mac Pro -> Mac Pro 3,1 (MP3,1)
Reboot
Download the latest MultiBeast for Yosemite if you don't have the latest;
Download the nVidia Web Driver for 10.10.2 >
WebDriver 343.02.02f01**
but do not run it yet;
Download the Software Update or the
Combo Update and run it to update to 10.10.2;
Re-boot with -v nv_disable=1 (if you get a freeze or KP, then try again adding -x);
Run the nVidia Web Driver installer but do no reboot when it's done because you have to...;
Run MultiBeast for Yosemite, just selecting your audio driver to install and, optionally, the 10.10.x TRIM patch;
When MultiBeast has completed loading the audio driver (and TRIM), close it out.
Re-boot by clicking the "Restart" button in the nVidia Web Driver installer window; and
Upon reaching the Yosemite Desktop, Repair Permissions again.*
* You can use the Terminal instead of Disk Utility if you feel comfortable with a UNIX command:
Code:
sudo diskutil repairPermissions /
** Note: Although I try to keep this link up to date, this may not be the latest driver. I have
never been able to successfully use the nVidia System Preference pane to update the driver. It freezes the system before completing the update. After the first time I tried it, I had to boot with the UniBeast USB thumb drive, download the latest driver from nVidia's web site and install the .pkg file. Upon rebooting normally, the system is restored and running correctly.
