Hector (H97N-WIFI / i5-4690 / 16GB RAM) with New Gigabyte 750 TI 2GB Graphics Card

The reading may be faulty but it's clear it's going at full speed - mine is the SC version would that make a difference. Grateful to anyone who can help!

I found some things online about fan control:

DSDT (laptops though, not sure if it'll work on GPU desktops): http://www.tonymacx86.com/hp-probook/72043-new-fan-control-dsdt-silent-fan-higher-temps.html

This one directly addresses the fan issue on GPUs and has a fix, but it involves risky BIOS flashing on the card: http://www.tonymacx86.com/graphics/65423-gpu-fan-control-nvidia.html

OK, this looks great, but I think the fact is that at the moment there is no fan control whatsoever, and all i'll be able to do is change the maximum fan speed. I might actually NEED the fan to spin at full speed at some point so maybe that's not the best idea. Might have to wait until Apple put a Maxwell in a Mac, unless I'm missing something really, really obvious.. I'm on GraphicsEnabler=No, and using the Nvidia driver. There's nothing else, is there?

Nope, you got it right.

Nope, you got it right.

Any ideas, Stork?

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:

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.

Thanks Stork,

I was able to get audio on my Z77X-UP5-TH working again in 10.10.2 by following the Realtek ALC AppleHDA Guide and the "No Audio Devices" Realtek ALC AppleHDA Guide which I only found after reading your post #2 in the 10.10.2 Update thread.
My fix was to enable both:

• /Drivers/Customize/Boot Options -> Kext Dev Mode
• Optional HDAEnabler (kext) -> Audio ID: 1

I built my new hackintosh yesterday with a GA-Z97-D3H, i5-4690, 8GB Corsair Vengeance. I would call it a success because it worked with integrated HD4600.

Then I tried to install the GTX 750 this way
Installed WebDrivers 343.02.02 on Yosemite 10.10.2. Sysdef to MacPro3,1
Shutdown
Plug VGA onto PCIE
Turn On
Flag nvda_drv=1

then I receive a grey screen with a (/) after a while booting. Interesting enough with -x nvda_drv=1 it boots and the system recognize the GTX 750 Ti 2047MB.

So any hint. I followed Hector with GTX 750, but couldn't get to work IG when GTX750 was plugged. At least no signal, only from GTX750

kext-dev-mode=1 must be in your boot flags.

Fixed my fan issue! I took the following steps.

Place EVGA 750SC in box.
Post back to Amazon.
Buy Zotac 750 fanless passive version....

Yep, that will do it.

The Yosemite 10.10.2 Security Update, released a couple of days ago, is not a trival update since it bumped up the Yosemite 10.10.2 build number which disabled the nVidia drivers. Then, we had to wait until today to get the updated nVidia Web driver. Hector was not an easy update. I won't bore you with what I had to go through to get Hector updated, but I'll explain what finally worked for me.

You'll need your UniBeast USB 2.0 Thumb Drive for Yosemite for this procedure.

Download the nVidia Web Driver for 10.10.2 for the Security Update > WebDriver 343.02.02f03** but do not run it yet;
Repair Permissions using the Disk Utility on the drive to be updated;*
Backup your current installation using Carbon Copy Cloner or SuperDuper - Do This;
Optional. Some User's report that they didn't have to do this step. YMMV. 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 into the BIOS and change the

Boot Priority to the UniBeast USB thumb drive;
Initial Display Output from the PCIe 1st Slot to the IGPX option;
The Intel Processor Graphics > Enabled; and
Save the BIOS and let it start the rebooting process;​

Shut down the computer by holding the computer case's Power Button down until the computer turns off;
Remove your nVidia Maxwell graphics card and connect up your monitor to your motherboard's DVI port or top HDMI port;
Restart the computer and boot into the BIOS to see if all the changes above are there;
If all is good with the BIOS changes, leave the BIOS to boot Chimera;
At the Chimera boot screen, use these flags: -v nv_disable=1 maxmem=(1/2 your memory if you have two sticks of memory greater than 8GB total)
Upon reaching the Yosemite Desktop, run the App Store program and download the Security update;
Reboot when the update is completed still using the UniBeast USB thumb drive and the Chimera boot flags: -v nv_disable=1 maxmem=(1/2 your memory if you have two sticks of memory greater than 8GB total)
Run the nVidia Web Driver installer and, when completed, reboot into the BIOS;
In the BIOS change the

Boot Priority back to the Yosemite installation drive;
Initial Display Output from the IGPX option to the PCIe 1st Slot option;
The Intel Processor Graphics > Disabled; and
Save the BIOS and let it start the rebooting process;​

Shut down the computer by holding the computer case's Power Button down until the computer turns off;
Reinstall your nVidia Maxwell graphics card and connect up your monitor;​

Boot as normal; and
Upon reaching the Yosemite Desktop, Repair Permissions again.*

Congratulations! You're done. Enjoy!
