[SCRIPT] Automating the installation of eGPU on OS X (inc display output)

Recommended Posts

i just tried to install driver with latest automate-eGPU.sh script. my MSI GTX 750 Ti shows up in system report > Graphics/Displays but 'About this Mac > Overview' tab still shows Intel HD5000. what is the problem here ? i tried both 0.9.6 and 0.9.7 script

My Mac is MacBook Air (13-inch, Mid 2013)

OS : El Capitan

i'm using MacBook Air display, no external display.

Hi @goalque,

0.96 works quite well on my 750m/Iris 2014, but can install this without using the web drivers? thanks.

EDIT:

- Possible to use Nvidia official driver for Kepler cards [-skipdriver]

What about on a Maxwell card, a GTX 970?

No external display means that only GPGPU is possible. For example, you can use Adobe Media Encoder & CUDA for hardware accelerated video conversion.

What about on a Maxwell card, a GTX 970?

Web drivers from Nvidia are required with a Maxwell card. No native support. Apple is in AMD camp now.

Image validation failed with a GTX 980. However, Media Encoder's OpenCL acceleration seemed to work.

hi @goalque, is there any way to active it on my Mac Display ? is an external display must-have ?

thank you for your answers

No, there is no known way. If there was it would be obviously implemented in the script. So, yes, for OS X you need an external display to use the eGPU for games or other things. The eGPU will not be used for games etc. on your internal display.

from what you said, does it mean we can use Macbook Air screen on Windows without an external display ?

Yes, for Windows there is Optimus support in case you use a Nvidia graphics card. Your GTX 750 Ti is fine for that.

In case booting Windows does not light up the internal display when your eGPU is attached you need to apply this mod to the EFI boot section after you installed Windows: http://forum.techinferno.com/apple-egpu-discussion/8558-%5Bguide%5D-macbook-enabling-optimus-internal-lcd-mode.html

Afterwards your Intel GPU will be enabled and you can use the eGPU on the internal display without any external displays. Already did this without issues when visiting a friend to play games.

Be warned though that this does currently not work with Windows 10. Your best and easiest go for the eGPU, Optimus and Windows is Windows 8.1.

First of all, thank you for your great job and sorry for my bad english...

My setup is :

MBPR 2012 GTX 650M

Akitio 2

GeForce GTX 660 Ti 2GB

PSU (450W) + Barrel adaptor -> Akitio + Molex to PCIe Conectors -> GeForce

I´ve used Version 0.9.6 as you recommendation for dGPU and I´m having random kernel panics after a frozen display.

I´ve used -clpeak with no problems and also Engine Heaven also with no problems.

I have two questions:

1- Do I need to install BETA drivers? I am not pretty sure if you are saying this to errin

2- As the problem looks like comes from how the system manages the internal GPU, Is it important to set up an specific configuration for te uses of the internal cards? I´m referring to disconnect automatic graphic change in settings or force the system to use only one card wit gfxCardStatus (I´m testing now disabling automatic changes and force with gfxCardStatus to use only the discrete card and no kernel panics in 2 hours)

Thank you for your help and tell me if you need to test anything with my hardware.

</none>

Looks like we have the same problem with the 650M I´ve the same Macbook as you but with 8GB RAM.

Have you try to force the use of the discrete card with gfxCardStatus? 2 hours without kernel panics and benchmarking and video playback... I´ll tell you with final conclusions

If you find another solution please tell me.

Good luck!!

EDIT: Just launch Dota2 in Steam and another shutdown... force de discrete card did´t work</none>

@Charly

I didn't use gfxCardStatus since the previous OSX 10.11 worked like a charm but the issue just occur when I'm in 10.11.1.

I played Dota2 for 6 hours watch video fro 6 hours but no problem came up but sometimes 5 mins after boot up it cause Kernel Panic. For me I think this issue is just random.

As from goalque said, beta driver from nVidia may fix this.

Tried the beta but didn't work can't boot to eGPU have to revert back again.

1- Do I need to install BETA drivers? I am not pretty sure if you are saying this to errin

Maxwell cards require web drivers from Nvidia. That’s the problem as the same driver handles both the dGPU and eGPU. The script downloads the correct driver automatically, and -skipdriver option is meant only for Kepler cards.

2- As the problem looks like comes from how the system manages the internal GPU, Is it important to set up an specific configuration for te uses of the internal cards? I´m referring to disconnect automatic graphic change in settings or force the system to use only one card wit gfxCardStatus (I´m testing now disabling automatic changes and force with gfxCardStatus to use only the discrete card and no kernel panics in 2 hours)

I’ve heard that v0.9.7 disables the internal screen completely with Nvidia dGPU equipped Macs, but does it stay stable? Have you tried gfxCardStatus “integrated only” mode? If you find a working combination (either with v0.9.6 or v0.9.7) so that the internal screen will always use Intel’s iGPU, it’s possible to automate this process.

FORGET THIS JUST CAN`T FIND DELETING THE POST

errin this Is exactly the same with my mbpr, last kernel panic was during Safari browsing so i can't find any clear pattern in what Is causing The problem.

Next i'm going to force igpu, i'll tell you any news

Is your egpu working in Windows? I'll try wirth nando soft but Is not finding the egpu

Thank you, I understand know.

Newer cards as 970GTX have official drivers or the problem is in all Nvidia cards? Im buying 970 gtx this week but this makes me thing about AMD cards.

In your opinion which option is smarter?

I’ve heard that v0.9.7 disables the internal screen completely with Nvidia dGPU equipped Macs, but does it stay stable? Have you tried gfxCardStatus “integrated only” mode?

Rigth now is late in Spain and so tired but tomorrow will try all combinations in 0.9.6. and explain everyting

Wow that's really good news, Im installing 10.11 in external USB Drive and confirm.

errin, Do you get Windows to work with the eGPU? I installed nando soft but can´t find the graphic card card before the compaction, I spend some time with it but I was not pretty sure that my eGPU implementation was working or not so i concentrate in OSX, now i know that is functional so i´m trying again, Any suggestion?

Yes no problem with Windows 8.1 and 10 only sometimes boot up can be frozen after the chime but if I successfully boot in to Windows it's 99% working fine.

You may tried to read the Implementation threads, as far as I know there are 3-4 threads with 650m MBP

Great news!!

I´ll find the threads and install Windows 8.1

I’ve heard that v0.9.7 disables the internal screen completely with Nvidia dGPU equipped Macs, but does it stay stable? Have you tried gfxCardStatus “integrated only” mode? If you find a working combination (either with v0.9.6 or v0.9.7) so that the internal screen will always use Intel’s iGPU, it’s possible to automate this process.

Ok, I´ve been trying different combinations no one is stable with v0.9.6:

1- Automatic gfxCardStatus = NOT STABLE

2 - Force dGPU with gfxCardStatus + ClamShell Mode (Rebooting with the Macbook Screen closed) = NOT STABLE (Internal screen is not recognized by the system And shows frezed image

3- Force iGPU = NOT STABLE (Start system without external screen connected to te eGPU force the iGPU and reboot, without that is not possible to force it)

4- Force iGPU + ClamShell Mode = NOT STABLE (Repeating the steps to disable internal screen in step 2) * I thought this could be the good one :(

So no luck at the moment...

What it looks curious to me is that my software monitor iStat Monitor shows the usage if the GPUs and when the iGPU is in use only shows the iGPU in the monitoring screen, but when the dGPU is in use you can see dGPU and eGPU in the monitor software, is like the soft only things that the eGPU is connected when the OS is using the dGPU when in fact in both situations eGPU is in use

@Charly:

I missed the fact that you have actually 600 series card which is Kepler. Uninstall the script (sudo ./automate-eGPU.sh -uninstall), run again with -skipdriver option and report if that helps. Note that only Maxwell cards and older AMD HD series are stable with AKiTiO. Some Kepler GPUs may work, some may not. PCIe only powered 750Ti is not a reliable choice either.

Therefore, your issue may be different than errin’s since he has a Maxwell (GTX 960). Did you have similar kernel backtrace, including com.apple.driver.AppleMuxControl?

Hey,

First of all thanks to goalque for his great job make it much easier to use a egpu. :eagerness:

I also want to built an egpu but I am not sure wether i should buy an gtx 970 or an and R9 390. I've read about many successfully builds with the nvidia in this forum but the 390 has more power to play games in wqhd. So my question is wether anybody has made experiences with the 300 series from amd.

Thanks for your help

sorry for my bad english

Thanks! R9 390 is a very powerful card and my favourite, but keeps crashing with AKiTiO:

Thanks for your quick answer.

Would it work with a r9 290x or crash every card from the r9 xxx series.

I don't want to buy a gtx 970 because I think i get trouble playing in 2560 x 1440 resolution.[h=1][/h]

As far as I know, crash happens with every card from the r9 series. This issue is somehow related to the AKiTiO hardware, it’s detected as x4 on OS X, but a multi-slot NA211TB is detected as x8.
