    It looked like borealiss got his thunderbolt egpu working with the diy egpu setup and he was using a 2011 macbook.

    OK so I bought the application and it seemed to install fine by running all 3 bat files it suggests in this article:

    http://forum.notebookreview.com/e-g...8851-diy-egpu-experiences-64.html#post6295529

    However when in menu mode, the application stops when I either disable the dGPU through it OR run the compaction. It's odd cos the cursor on the screen keep flashing but does not respond to any input. When running the compaction it stops on the following line:

    copy R:\config\pci.bat (ramdisk) -> c:\config\pcid.bat (drv) ...

    Anyone seen similar?

    Hi Guys - I am using the TH05 on a mid 2011 17'' MBP (the first one with thunderbolt). My aim is to get the eGPU working under OSX (10.8.2). I am using a GTX 580 3GB (PC version, not EFI flashed). The issue I have is that in system profiler when clicking on the PCI bus I get "can not read from card". CUDA-Z shows no CUDA cards, GPUSNIFFER shows only my internal cards.

    Do you know what I need to do?

    Muthma,

    So far, no one has gotten an egpu to work with os x over thunderbolt. This is because the card is not "thunderbolt aware". It has only been proven to work under windows 7.


    Tekno,

    I'm not familiar with the diy setup. You might post on the diy egpu experiences forum?

    Thanks for coming back. It is interesting that the card is visible on the PCI bus. I think it has to do with the MBP not looking for any other cards than the internal ones when it boots.

    Oh wow! Thats interesting. Have you downloaded the nvidia desktop drivers for mac? If you search for diy egpu mac experiences there should be instructions to get the drivers downloaded. You just have to edit the distribution.plist so itll install on your macbook. Good luck!

    Did that. Downloaded the nvidia drivers from their website and added my MacBook Pro and installed it. I saw that new kexts were installed as they went bcak to default. But still the same results. Also after I added the device ID again for the gtx 580 in the nvidia kexts. I feel I am close! I think the issue is that the MBP is not loading the kext for the GTX580 because it assumes no GPU other than the build in will be present. Maybe during the boot it does not look for anything. Not sure there is a way to force the kext to be loaded. I have attached what is loaded right now

    I think it is the thunderbolt problem. Since it's connected through thunderbolt, it needs drivers so it can be detected through TB. So far, Apple hasn't allowed graphics cards to be viewed under os x without a ton of editing files. If you look on youtube and search MediaProsUK, they have gotten a NVidia quadro 4000 working on os x via thunderbolt; but they don't say how. All they said was it's something you shouldn't do (I really wish they could just put out a guide of how they did it).

    Why would you use an egpu in osx? there not many games out on osx. Just install windows and enjoy your egpu:p

    Its mostly for people who use 3D editing software. An os x compatible egpu could essentially wipe out most mac pro purchases.

    But yes, windows does seem like the main os for e-gpus :)

    Well, I've finally got my Mac back off a friend who was using it for some app development work and I've decided to use it as my "main" system.

    I've refined what I had working previously and the new bootcamp drivers greatly improve the stability of this setup.

    There are still inherent problems with this though. The Intel HD3000 is not presented to the OS entirely correctly. If I don't disable the device the internal display output does not work.

    Just to be clear on this, Windows is installed directly in UEFI mode. The 2011 models don't seem to be truly UEFI 2.0 compatible. This leads to issues with graphics in particular.

    This mainly means that Optimus will not work on these older machines.

    This is fixed in the latest models I believe, but I'll have to test that with a friend's machine before I upgrade to one.


    Anyway, the point of this post is to let people know that I'm still around and in a position to test various things, however, I'm not really sure what the current state of play is on the thunderbolt front.
    I've had a quick flick through and things seem fairly similar to when I last checked the forum, so if anyone has anything they'd like me to test with this setup, just shout out.

    The current setup( excuse the mess, I'm in the process of moving house):

    I know I may be just a little bit late but have you heard of lucidlogix? They make this great software that doesn't capture video but harnesses the graphics power of a video card that you don't have any displays connected to and lets you display your games on say your intel HD graphics. I was interested in using their software but then had the same idea that you're doing, only with a retina macbook pro. do you think it would be possible and can you test it out with them? I want to buy my mac for christmas and really want to know what my options are.
