system Posted January 9, 2015 Share Posted January 9, 2015 I've used 3 different cards with my MBPr and Akitio now. They can all be used with external monitors bit you must boot with the monitor unplugged and plug it in within the first few seconds after your desktop loads. When I learned this, I was just remembering that even without an eGPU, my Thunderbolt Monitor wouldn't turn on until my desktop loads during bootup and thinking it was worth a try. It works almost every time. If it doesn't work for some reason, I just reboot. It is a little annoying but it works and it's worth it.I would expect that there is a modification we could use with the tunneling commands in the kext files that would change this because my guess is that the issue has to do with the fact that the Apple Thunderbolt monitor and some of the Thunderbolt hubs are the only peripherals that could tunnel to other devices through Thunderbolt before the kext modification. Now that I think about it, some of the extra Kexts may not be necessary for use without enhanced graphics. I'll try that in the next few days and post my results. I may be onto something here.Sadly, this did not work, my Asus remains as inert as before. Staring glumly at me with its unused display. Good luck with your tinkering!MVC: I haven't installed CUDA drivers yet. I am today though. But the monitor connected to the 970 acts as though it is receiving no input. However, the card shows up in System Profiler. Go figureEDIT: CUDA installed!DOUBLE EDIT: Reinstalled drivers, fixed GTX 970 monitor issue, however, screens plunged in to rMBP remain blank.

Is that what you are experiencing? Quote Link to comment Share on other sites More sharing options...
system Posted January 11, 2015 Share Posted January 11, 2015 Sorta.Firstly, my apologies for the lack of clarity (Note to self: don't post while donating blood)Secondly, my problem is that any display plugged directly into the rMBP does not work, and only one works through the 970. I would like to either be able to drive them all off of the GTX 970, or drive all but one of them off of my rMBP and the remaining one off of the rMBP (It's a 4K monitor)Thirdly, while that was my problem at one point, a driver reinstall solved it.

Is it stable? do you game, render or both please ? Quote Link to comment Share on other sites More sharing options...
system Posted January 20, 2015 Share Posted January 20, 2015 Just to be sure, your system is now working with 10.10.1, the 970 and your 4k display connected on the eGPU ? which web drivers please ? Is it stable? do you game, render or both please ?The setup is correct. Im using 334.1.02b02. It is sometimes stable. I game, although usually in windows. I do not render. I say sometimes stable because it occasionally does not connect to the eGPU display. This is solved by repeating the install from scratch. I'm so sorry about the clarity of my posts. I rarely visit forum sites, and it shows.EDIT: Drivers are NOT stable, I repeat, drivers are not stable and require a reinstall every time I back from the OS X default drivers. This is frustrating, because I do like a battery life of more than 6 hours. Quote Link to comment Share on other sites More sharing options...
Benhur Posted November 17, 2015 Share Posted November 17, 2015 Hi I work with color Davinci Resolve, transfer, and video 4k, 5k.... I looking for Akitio chassi, and video card, you would have a suggestion what PCi more cheap and with good performance?my macbook pro retina mid 2014, 2.8GHz, GT 750M, OS X 10.9.5.I see various GPUs requiring drivers, and a Apple don't allows.

Benhur Posted November 17, 2015 Share Posted November 17, 2015 and video card GTX don't have the 100% performance, it is in chassi via thunderbolt 2 (maximum 20Gbs) the GTX is 3.0 connection.am I right or wrong? Quote Link to comment Share on other sites More sharing options...
Dschijn Posted November 17, 2015 Share Posted November 17, 2015 @Benhur: Rendering Apps don't need that much of bandwidth! You can use an eGPU easily for that!You can use any eGPU that is in your budget. Quote Link to comment Share on other sites More sharing options...
Benhur Posted November 19, 2015 Share Posted November 19, 2015 would have many problems, using macbook pro retina mid 2014 with expansion chassi Akitio and GPU?whats GPU is indicate render 4K Video? settings with mac AMD or Nvidia?there is more performance with thunderbolt 2 Quote Link to comment Share on other sites More sharing options...
Dschijn Posted November 20, 2015 Share Posted November 20, 2015 @Benhur: If your rendering app needs CUDA, you need a Nvidia card. Quote Link to comment Share on other sites More sharing options...
mdt Posted March 11, 2016 Share Posted March 11, 2016 (edited) @MVC What NVIDA drivers are you using for your Titan Black Cards? I've followed the instructions posted here And my setup is the following, but I can't get the eGPU recognized...any guidance would be appreciated. MacBook Pro Late 2011 OS X 10.10.5 (14F1605) Processor: 2.8 GHz Intel Core i7 Memory: 16 GB 1333 MHz DDR3 Graphics: Intel HD Graphics 3000 512 MB Echo Express lll-D Corsair CX Series, CX600M, 600 Watt (600W), Semi Modular Power Supply, 80+ Bronze Certified NVIDIA Web Driver: 346.02.03f05 CUDA Driver Version: 7.5.25 -- but it says no GPU Driver Version is found. I've tried the after installing, but I've had no luck. Quote sudo kextcache -system-caches One thing I suspect is that my install of 10.10.5 is not fresh and I may need to do the entire process after re-installing, but the key thing I'd like to confirm is the NVIDA web drivers support the Titan Black card even though their site doesn't state that fact.

Dschijn Posted March 11, 2016 Share Posted March 11, 2016 @mdt For OSX support you might want to ask here: https://www.techinferno.com/index.php?/forums/topic/7989-script-automating-the-installation-of-egpu-on-os-x-inc-display-output/ The script should also cover your card (ask goalque to make sure) and you can skip the hassle with the "oldschool" guide. 1 Quote Link to comment Share on other sites More sharing options...
