  1. Finally ! The script v0.9.6 is working perfectly, everything is very stable, i just can't boot with 2 external monitors. I have to boot with 1 monitor attached and then hotplug the second one into the graphic card but, after that, it works like a charm. The retina display switch automatically from Iris pro to the GT 750m. I've done a benchmark to test the eGPU. Here is the result in comparison to other results you can found here (Unigine Heaven 4.0 Benchmark Scores | TechPowerUp Forums ): Regarding the issue, i've realized that the GC was definitely the problem when i had tested the Akitio setup with a GeForce GTX 560 Ti and everything was working (unless the internal screen not recognized, an issue which come from the v0.9.7). Now my GC is replaced and here is the setup at this state : I just wonder how it is possible to optimize the system to use at least 80% of the capability of the 980 TI ? Is it really limited by the 4 lane PCI Express 2.0 interface of the Akitio (which is 5.0Gbps) and is it possible to double it with a second thunderbolt cable ? There is a great article about the difference of efficiency between several configuration in PCI-E : GeForce GTX 980 PCI-Express Scaling | techPowerUp For a GTX 980 there is not so much contrast so maybe a GTX 980 TI manage more data than 5.0Gbps ? That being said, the result is still very good and it is so convenient to be able to use the dGPU for other operations on the internal screen ! I realize now that thanks to your script it is very easy to use a eGPU on OSX, even for a beginner . Now i'm going to work on making a box to be able to transport it safely. I will write a thread soon in the Implementation Guides section once everything is in place. Thank you again for the help !
  2. I have tried the new script with the -a mode and i can notice several bugs with my macbook pro : - In the case i don't plug the egpu at startup the 750m is attributed in system preference as the main graphic card but my retina internal screen is recognized as a 47inches screen and it is not handled properly (glitches at startup, very slow etc...). 47inch retina + gt750m.txt - If i plug my egpu with external monitor, it do the same glitches but it doesn't cause a kernel panic. The gtx 980 ti is recognized by the Nvidia Web Driver, and it's written in "about this mac" "monitors" that both screen as driven by the egpu. But when i go to the system report i can see that in fact the dgpu is driving the internal monitor et the gtx 980 ti the external. Like always, when i try to launch the benchmark, it cause a kernel panic. 47inch retina + gtx 980 ti + gt750m as main GC.txt Whether i put the script in -a or -m mode (plug or not the egpu) my internal screen is not recognized anymore, i have to -uninstall the script so that everything come back to normal. ps: i've made a custom connector between my PSU and the DC Plug of the akitio, so it's not the issue. I hope this feedback can help and thank you again for your work.
  3. I have read this thread -> http://forum.techinferno.com/provisional-guides/10516-2013-15-mbp-gt750m-gtx980ti%4016gbps-tb2-akitio-thunder2-win8-1-osx10-10-%5Bcascas-3.html. Still no luck with my setup, it doesn't help nether if i select my external monitor as primary. It seem that no matter what i do to effectively use the graphic card (Unigine etc), it will crash immediately. It would be great to have a new script that allow that (if it could help in my case) ! ps : I'm using the original power supplier that was in the box to drive the Akitio as i don't have any adaptor from 6/8 pin to barrel plug currently. It could be the issue ?
  4. Many thanks for the help. Unfortunately the problem is not solved with 10.10.5 and the new driver 346.02.03f01. I have removed the PCI riser and put the GPU directly on the Akitio card which is now powered with the original barrel cable. I have exactly the same issue described in my last post. What works : - shut down the computer, plug the thunderbolt with egpu without external monitor, boot the computer -> the egpu is recognized by the graphic driver 100% of the time. - reboot the computer with egpu without external monitor -> the egpu is recognized by the graphic driver ~20/30% of the time. - after a kernel panic i have to leave the computer reboot, shut it down, boot it again and shut it down to be able to recognize my egpu again. - if i try to hot plug a monitor to the egpu when it is not recognized by the graphic driver i will have to shut down the computer, boot it again and shut it down to be able to recognize my egpu again. With external monitor when my egpu is recognized : - hot plug external monitor in DVI after shut down & boot -> external screen as a second Desktop, very unstable, it will shut down the computer and make a black screen a few seconds after. - activate before in gfxCardStatus integrated graphics only and hot plug external monitor in DVI after shut down & boot -> external screen as a second Desktop, remain stable but it is driven with the iris pro as i can notice in the section « about this mac », i am able to switch to dedicated only without crash but it is now driven by my dgpu (gt 750m) and it crash as soon as i put a google chrome page in it. - hot plug external monitor in hdmi after shut down & boot -> the screen of my desktop flash in the external monitor for ~1sec and it cause a kernel panic. - activate before in gfxCardStatus integrated graphics only and hot plug external monitor in hdmi after shut down & boot -> always cause a kernel panic. - activate before in gfxCardStatus integrated graphics only and hot plug external monitor in hdmi after shut down & boot -> it recognized my internal and external monitor as driven by the gtx 980 ti but it shut down after ~10 sec and i tried 4 more times and never succeeded to make it work. - Deactivate the automatic permutation of the graphic cards in system preference, boot the computer with the egpu and the external monitor in hdmi -> once again both internal and external monitor are recognized as driven by the GTX 980 TI but it shut down shortly after but never succeeded to make it work again. I noticed that the option to automate graphic switching reactivate randomly after several restarts but i really can’t see any pattern outside of the fact that my computer can recognize the egpu. Here is the output of the eGPU + hdmi monitor after hot-plug -> OSX 10.10.5 GTX 980 TI hdmi output.txt The output of the eGPU + hdmi monitor after hot-plug when it the eGPU is recognized as the main GC for both monitor -> OSX 10.10.5 GTX 980 TI as dedicated graphic card.txt
  5. Hello, First i want to thanks all the community for all the devotion and goalque for his wonderful script. I have an issue with my setup : - macbook pro 15’ mi-2014 with GT 750M - Akitio - PCIe Riser with molex - XFX ProSeries (Black Edition) 750W Fully Modular 80+ Gold Power Supply - Palit Nvidia GeForce GTX 980 Ti Super Jetstream Graphics Card I have tried countless hours to make it works without success. I was running the script on a clean install of OS X 10.10 Yosemite after having reset the NVRAM doing (Command (⌘), Option, P + R at startup). It was recognizing my card after the reboot as an « Nvidia Chip Card ». I have tried to hot plug my external monitor in DVI directly into the GPU, my computer could recognize it as an external screen but it was very unstable and every time i have tried to launch the benchmark Unigine Valley in this screen they were a kernel panic. The « automatic graphics switching » was turned on, « integrated only » selected on gfxcardstatus and FileVault disable. I have made an other clean install of OS X 10.10.4, did the same with NVRAM etc. The script installed the NVIDIA Web Driver 346.02.02f03. My computer was able this time to recognize my card as a GTX 980 TI I have hot plugged the DVI, it was very unstable too. I tried to launch Unigine in my internal screen and the result of the benchmark was very bad. I have tried all the combination possible, with or without -a mode etc with no success. The only stable thing was that my computer recognize my eGPU if i plugged the thunderbolt cable just after the chime at startup and if they were not a kernel panic before. So i tried with a different monitor in hdmi. It was much more stable, and the computer recognized the external screen as a monitor associated with my eGPU But unfortunately same error with the kernel panic each time i try to launch the benchmark on the external monitor. I did exactly the same also on a second partition with El Capitan GM and the SIP (Cmd + R, « csrutil disable ») disabled in the terminal, same errors... I have made two file for the eGPU with DVI plugged or hdmi with the method you described here : 1) Unplug all USB devices 2) Boot into OS X 10.10.3 with the eGPU + monitor plugged 3) Open OS X Terminal, and copy-paste the following command Code: ioreg -l | perl -pe 's/("serial-number"|"IOPlatformSerialNumber"|"fmm-computer-name"|"IOConsoleUsers") = [\("<](.+)[\)">]$/\1 = ""/g' > ~/Desktop/output.txt I can send it to you goalque if you will or anyone if it can help. I will try to do it again tonight with 10.10.5 and a newer web driver, maybe my specific model was not recognized yet in the driver as it is very recent or a kext file is not edited properly but if it is the case i would definitely need some directions… Thank you for your time ! Cheers
