This is an article about how to recognize GPGPU via Thunderbolt external PCIe box at MACOSX 10.9.4.
Up to 10.8 was working. but after updating to 10.9 Mavericks, your GPU might not working. Or it does not work with GTX TITAN Black or 780Ti.
It is because GeForce driver in the 10.9 (Mavericks) is old.
- Mac (MacBookPro Early 2013)
- NA-211TB (New version. Power up to 300W PSU)
- Text Wrangler (Text Editor)
- CUDA driver mac edition (from NVIDIA)
- NVIDIA Web Driver (ver 334.01.02f02) *modified version
Downloading of the latest driver refers to the following URL.previous article.
ok, let's start.
Rewrite a kernel extension file. *see previous article
Download and Install the CUDA driver.
Download and install a modded Web driver.
(See the the following threads: http://forums.macrumors.com/showthread.php?t=1748213 )
Usually, NVIDIA's official Web driver will do a system check.
Official web driver can only be installed on MacPro 2008, 2009, 2010.
If you are using a iMac or Mac Mini or MacBook Pro, you can't even install.
But Modified Web driver avoids the system check.
Modded Web driver file name is ModdedWebDriver-334.01.02f02.pkg.

Finally, clear the cache of the kernel extension.
Start a terminal.app and type the following command.
sudo kextcache -system-caches
To turn off the power once, connect with Thunderbolt cable NA211TB and mac, and turn on the power.
|If successful, GPU name will be displayed here.|
If it does not work. Many mistakes's rewrite of the kernel extension.
Please check the contents of the kext file again.
GPGPU board that is able to operate confirmed by external expansion box up to the present are as follows.
- GeForce GTX760
- GeForce GTX780 6GB edition
- GeForce GTX680
- GeForce TITAN
- GeForce TITAN Black
