Really dont know, maybe it was a faulty Akitio or faulty drivers or just a Windows problem... but after some time of gaming or when it was loading a new zone i was getting a black screen and sometimes a BSOD. Try it and if you have problems just send it back .

wait for release and updated GPU drivers.

Yes, should be plug and play.

Looks like safe mode. Maybe a problem with your edited .kexts? Have you tried KextWizard?

M4800 (see sig.): AMD Radeon R9 290X video card benchmark result - Intel Core i7-4810MQ Processor,Dell Inc. 0T3YTY Its the same problem with my old W540 and Windows 8.1 (lower physics score) then with Windows 7 . http://www.3dmark.com/fs/2548533 (W540 +W8.1)

Or wait some time to get a W541 with TB2.

You need the DIY eGPU Software....

Its a little bit strange. I use my Macbook (see sig.) at home (eGPU sig.) and at work (no eGPU) and when i unplug everything expect eGPU and power-adapter before boot i get the monitor detected to 90%. When i plug in my mouse and my Thunderbolt-Dock before boot its about 30% and i have to restart several times to get it working. When its detected its working fine no crash or anything. Ive tried 3 different R9 290X models (reference designs and custom ones) but i always get a freeze some seconds after boot. Maybe its a framebuffer problem ([HOW TO] Modification of AMD FB + Clover injection - ATi - InsanelyMac Forum I havent tried it.

Yes. Maybe a problem with the Sonnet Echo. It should work since some MacPro and Hackintosh users are using it.

Ive tried a R9 290X (Saphire TRI-X) yesterday with my Macbook and OSX. It gets recognized after editing the .kexts but after about 5 seconds i get freeze or beachball and freeze some seconds after that. I also tried a fresh install of OSX but same problem. Some time ago i was trying it on my W540 with an ASUS R9 290X and it was nearly the same problem in Windows 8.1. It was working and after some seconds i was getting a bluescreen.

Always after each restart? Because i sometimes dont get my monitor detected and i have to restart several times before it gets recognized with my NVidia. Thanks.

for NVidia web Driver you have to: + you are on 10.10.1 with the newest drivers from NVIDIA DRIVERS Quadro & GeForce Mac OS X Driver Release 343.01.02

enabled?

Maybe TDPThrottle look at the physics score and compare. Try Throttlestop and undervolt CPU.

OSX driver for 10.10.1: Quadro & GeForce Mac OS X Driver Release 343.01.02

780Ti isn't working without WebDriver, but i have read that even the 750M GT is getting better benchmark results with the WebDriver instead of the native OS X driver.

#140

Update OS X 10.10.1: - i had to edit AppleHDA + IONDRVSupport with (standard): - and NVDAStartup with: (since there is no NVidia Web Driver for 10.10.1 (14B25) at the moment. Installed, repaired and KextCache .... Maybe you have to: Since the NVidia driver is reseted to native OS X driver.

Sorry switched to a Macbook and OS X .

After installing the web driver and after editing the .kexts. You can check the current boot args with

Use: or NVidia Webdriver wont load.

1.1 while the GPU-Z benchmark is running? Expresscard is set to Automatic (=Gen2) in BIOS?

Its a little bit strange with detecting and not detecting the eGPU/Display and OSX but like i said most of the time its working this way.
