Hi guys, 

I’m new here so hi I hope you are all well 🙂
Please forgive me if this post is in the wrong section or my typing is bad, I am on my old iPhone because my MacBook is currently not working properly due to what I am about to explain.
Please bare with me and I will try my best to give you all the information I can so that at least someone could please help me as I’m in a terrible situation right now regards my set up and it’s recent failure. 

I am current using OS X 12.6 Sierra and I have a MacBook Pro retina mid 2014 with thunderbolt 2 (I think) and a Nvidia 750m and Intel iris inside. 
Over a year and a half ago I bought a bizonbox 2s with a 980ti inside and I got it imported to the uk from the states, from bizontech themselves. It cost a fortune and after reading up on the negative and positive of bizonbox’s i do realise I spent a lot more than I should have but I was new to this and went for simplicity at the time. That been said the guys at bizon have always been supportive and email any suggestions and fixes when a problem has arose. I’m fine with all that. 
I use my egpu to render using octane and redshift. I’m not tech guy I’m a designer so hardware and terminal scripts fly over my head. I have had no major issues regarding my setup and I’ve been very pleased until now. 

I hope someone could help me, I would really appreciate it. My OS X security updates are up to date and so too are my nvidia web drivers however in order for me to explain my problem in detail I will tell you how I set up egpu and what problem I have right now. Thank you for getting this far. A long way to go still, I appreciate your attention. 

To install my bizonbox I connect it to my MacBook trough the thunderbolt port from the back of the bizonbox to my port on the MacBook. I connect my external monitor to the back of the bizonbox too. It’s a contiq 21 ux, this is my main monitor. I install a preference pane from bizon that is in the setup instructions pdf. I have to then go into recovery mode on my MacBook and in terminal ‘ csrutil disable ‘. I then boot back up. Now there is a 2 step process in the bizon preference pane I hit step one and then I reboot and then step 2 downloads and installs the nvidia webdriver. I reboot  and my second monitor is read, already set as primary monitor. Energy saver is off so my laptop doesn’t sleep, graphic switching is off and mirroring is off. All works well and I have had no real issues. 

So my problem  —

Yesterday i I was watching a video and my screen started to flicker and went blank (black but everything was still running). I rebooted and when my MacBook gets to the loading screen the bar gets half way and then the screen flickers, the beachball spins Erratically and then the screen goes blank. This has destroyed my ability to work so I’m desperate for help. I have hardly slept and after today I don’t have a day off for a whole week so I’m reaching out. I’ve been back and forth with bizontech via email and been online and can’t find an answer. I come across the community here felt it was worth a try. 

If if I unplug my egpu the flickering is now on my MacBook Pro on startup. I have to go into recovery mode, reinstall a fresh copy of Sierra over my current one and I can only then get back into my MacBook , logging in fine etc. I plug my external monitor directly into my MacBook and both screens work fine, no flickering etc but I have no egpu.

i have tried to uninstall the bizonbox pref pane, uninstall the nvidia web driver and start again but as soon as I  go through the installation steps and the nvidia web driver is installed (I believe always with the latest update) and reboot, the screen just before the loggin box appears, the flickering starts and then blank, back to square one. I have installed a new copy of Sierra just in case there was a conflict with my time machine back up but as soon as I install the webdriver through the bizonbox pref pane the issue arises again. Each time I have to boot up in recover mode, reinstall Sierra and wait quite a while to be up and running again. It’s driving me crazy, I’m so tired and stressed out because I need to use my egpu. The guys at bizon have tried giving me various instructions, even some terminal files to run the instillation that are not through the preference pane but as soon as the nvidia driver update is installed, I reboot and I’m back again with the same issue. 

I did have my macbook working, reading the egpu in my ‘about this Mac - system info section’. It said that the aikito node was connected. In the bizonbox pref pane it said it was connected but my external monitor was not registering with it. The nvidia web driver was installed and no issue other than my external display wasn’t registering the egpu therefore it wasn’t active. So I went to step 2 of the bizon box instillation. And it said downloading/ installing and once done I had to reboot as this installs the nvidia web driver. When I rebooted the problem was there again on startup. 

So so everything works fine without my egpu connected but as soon as install the web driver it creates the problem on reboot. 

Could anyone/someone please advice me on what I can do to get my egpu working again. I’m confused lost and tired but I have to fix this today . I appreciate any help in advance. 

Thank you
greggerz

@greggerz Last I remember, Bizon were using @goalque's solution so I can help with respect to that, not the re-packaged software they provide you (like the preference pane). You can refer to this guide, where I set up precisely the same configuration. Ignore the instructions for High Sierra, since you are on Sierra.

Thank you for getting back to me. Before I saw your post I decided to use internet recovery to start from scratch and right now creating a usb installer to fresh install Sierra. I will follow your method mentioned and hopefully I will be able to fix this fingers crossed. 

Im really grateful for your advice.

@greggerz Good call. You should hopefully be up and running in no time.

Hi,

I managed to get Sierra back on my Mac and followed the link you gave me and went through the instructions but unfortunately the same thing happened.
After it installed everything through terminal and it rebooted my external screen started the flickering and then darkened coming slightly on and off and then the screen went blank but still active. 

Its strange how everything was working perfectly and suddenly this happened yesterday. If I unplug my egpu and reinstall Sierra again over the top of the current one the MacBook works and so does the external display when connected directly to the MacBook. 

I dont know know what to do, I’m so tired but I have to fix this and I appreciate your help I really do. 

Do you think I should try install high Sierra and try the method to get it working there? My time machine backup is set to Sierra but even so if I can get it to work there is some promise. 

Appreciate your advice 
thank you

@greggerz does the display work fine when directly connected to Mac? Nvm you answered this. Does the GPU work fine in a PC or different Mac? It could possibly be a hardware issue, maybe.

So I’m getting somewhere ... for now. 

I reinstalled the freah copy of sierra and then I upgraded to high Sierra. I went through the setup and well it worked. My egpu registered and both monitors were working. So that’s a relief. I kept stalling upgrading to high Sierra because with Sierra my MacBook setup just ‘worked’ and I didn’t see the need to upgrade. I don’t have a choice now. 
I am now downgrading to Sierra so I can reinstall my timemachine backup because I have all my design software and custom preferences that took over a year to get right on there. Then I will upgrade to highsierra so I don’t lose my personal settings. Fingers crossed. 

I don’t know what the problem was. Without the egpu my MacBook and external monitor worked together on Sierra. When I installed the egpu it fails whilst on the loading screen, I say fails, it just flickers and then goes blank whilst still slightly flickering.  I will report my progress when I’ve upgraded my time machine backup. Thank you for getting me this far.

Hi Mac_Editor

I managed to get my egpu working on high Sierra but when I use certain applications ie cinema 4d, the interface is incredibly slow, to the point I can’t use it. Photoshop doesn’t register my 980ti in its advanced graphic processor section, zbrush is incredibly slow too. This means I can’t use my software due to the lag in all my creative applications. 
 
Would you happen to know a fix etc? 

Im glad I got it to work but on Sierra it was flawless but high Sierra I can’t use it due to the performance drop. At least I know my egpu works so it must be to do with Sierra which is such a shame. Can you please advice me I would really appreciate it. 
 
Thank you

@greggerz Could you add your system information to your signature - it really helps me keep track.

On High Sierra, try using set-eGPU for your apps.

Hi Mac editor , 

sorry to bring up this post again but I was hoping for some advice if possible. 

I got high sierra up and running. I do have a few graphics glitches on web pages and I have noticed that octane seems to show I have less gpu memory than I did when on Sierra. 

Im considering downgrading to El Capitan because it seems closest I can get to Sierra I was using before I had problems. 

Would you you recommend the downgrade? Do you know if high Sierra is more demanding on my system and will El Capitan be less demanding and better to use compared to high Sierra? All my applications I use worked fine on El Capitan when I began my egpu journey and I also liked the performance of Sierra. I just feel (and it may be just me) that high Sierra is demanding more from my cpu and gpu. 
I also don’t know if my internal MacBook graphics card is been used due to the script you suggested I use ( I chose option 1, so my egpu is used by all applications ) so I may be having less gpu power in octane because my internal and egpu are now using the one card for everything rather than finder, cinema 4d interface using the internal gpu. 

What are your thoughts on this, stay with high Sierra or downgrade to El Capitan because I will get less demanding cpu and gpu therefor more performance ? 

Ps if I stick with high Sierra is there a way I can use my epgu only for octane, redshift etc and still use my internal graphics for the interface of applications etc as to not choke my egpu? 

Apologise for all the questions. I hope all all this makes sense and I’m grateful for your input.
