  1. What do you mean by Optimus way? The internal display graphics are accelerated using NVIDIA optimus. Generally when I run into issues (on Windows 8.1) for whatever reason I try: 1) Switching around thunderbolt ports on both the MacBook and Akitio chassis 2) Running a clean install of the NVIDIA drivers
  2. I recommend trying to get Windows 8.1 to work first. I have had trouble with Windows 10 and never got it to work for me. I noticed your model is a macbook air, so it's possible your results will differ. It seems that installing with bootcamp and bootcamp driver is fine. Just going by this thread, @bluecitrus and @Syncytia have semi-successfully used it for booting up Windows 8.1 installed with boot camp. They both seem to have trouble booting up consistently though which I think may be due to them installing on the Macbook internal SSD. I installed Windows 8.1 on an external drive I listed in my first post in the thread. I rarely have any issues in booting up with my eGPU and Windows 8, so I recommend you to try use the external drive if you can. I am currently unsure on the difference between booting up Windows from external vs internal drive, so I'm just speculating.
  3. Windows automatic repair will come up if Window's is unsuccessful in booting up after two tries or after a blue screen of death. You can get rid of automatic repair by booting into Windows successfully without the eGPU connected. When does the black screen happen? I have never gotten just a black screen after selecting Windows from the boot menu (menu from holding option key at power up). I will sometimes get a screen where the Windows 8 circling dots just loop forever, so I force power off the MacBook and try again.
  4. It seems that the ebay seller no longer offers the pre-fabricated cable.
  5. Great to hear @bluecitrus! I've observed similar things in trying to avoid the 'loop' you described while booting into Windows 8. It is not common for me to encounter the 'loop' though. Do you use Windows installed on the internal drive or external drive? I am curious to know if Windows on internal/external drive has any effect on the booting reliability. @qqq66660 No, enabling optimus at boot does not seem to be needed. Post #77 - #80 here http://forum.techinferno.com/mac-os-x-discussion/8558-%5Bguide%5D-macbook-enabling-optimus-internal-lcd-mode-8.html seems to imply that enabling Optimus using Evo*'s method isn't helpful.
  6. @mvpzzp 3D mark on windows 8.1. You can enable eGPU using goalque's script (instructions in my first post in topic). Enabling the external display is just plugging your monitor cable into the GPU.
  7. They claim to support hot plug and play capability with all Mac models. I wonder what they're doing different.
  8. I was able to increase my firestrike benchmark graphic scores by changing some power management options. I changed the Windows power option from 'Balanced' to 'High Performance', and I changed the power management mode within NVIDIA control panel from 'Adaptive' to 'Prefer Max Performance'. My external display score went from 8767 to 9576 and the internal display score went from 7797 to 7971.
  9. I think if the backup file is missing then the easiest fix is to back up all the data you want to keep then factory reset. I don't use the EFI boot on my internal drive, so I can't cross check what the optimus mod actually does to the EFI folder. - If the optimus mod actually overwrites files in the EFI folder then restoration isn't possible without the back up file. - If the optimus mod just adds files to the EFI folder then you could check whiles files are added and just delete them. Also I don't think the commands given in the first post on how to restore the EFI from the back up file totally works. It seems using the ditto command again will just merge the back up EFI file and the Optimus modded EFI, so the additional Optimus files aren't actually removed.
  10. @JoshS0515: I've seen similar issues to you in Windows 10 and a 2015 13" MBP. I never ran into your issue #1, but I did get frequent boot up hangs with Windows 10 (the circling dots at boot up just circles forever). I also had the same issue as you in #2. The eGPU was recognized and usable with an external monitor, but the wifi adapter was not working properly. I saw in Device Manager that the Broadcom adapter did not boot properly. Disabling/Enabling it from within Device Manager did nothing. I plan to just stick with Windows 8.1 until Apple explicitly supports Windows 10 with boot camp.
  11. @jackfsqyj: Yeah, there is some noticeable coil whine when the GPU is in use. I use headphones though, so it doesn't bother me too much. @Syncytia: Great! Hopefully you continue to have good boot ups. I get a boot up hang for Windows 8 maybe every 1/10 tries. I didn't do anything extra for Optimus to work. Just installed all the components in NVIDIA driver install, booted up with eGPU into Windows 8, then optimus is ready to go.
  12. If you're talking about freezing at the EFI boot menu then here are two things to try. 1) Use goalque's shell script with -a mode (http://forum.techinferno.com/mac-os-x-discussion/10289-script-automating-installation-egpu-os-x-inc-display-output.html). This modifies a NVRAM parameter that can help with hot plugging the eGPU at the EFI boot menu. 2) Try the power up process method I use here (http://forum.techinferno.com/implementation-guides-apple/10614-2015-13-macbook-pro-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-osx10-10-%5Btranj10%5D.html). I have no issues getting the eGPU and MacBook to fully power up at the same time when I use this method. I am not sure why it works, but it does for me. If you mean the freezing happens while Windows 10 is booting up, then I had the same issue, and I just went back to Windows 8.
  13. I tried out Windows 10 (clean install on external drive) on the 2015 13" MBP, but it didn't seem to work out too well. I was getting several boot up hangs at the Windows circle dot loading screen. When I did get successful boot ups, the eGPU is recognized, but the wireless Broadcom adapter in the MBP would be disabled. I don't think Optimus was working for me either. When I looked in the NVIDIA control panel within the PhysX sub menu, the Color LCD (MBP internal screen) was attached to Intel Iris and only my external monitor was attached to the GTX 970. When I ran 3DMark Fire Strike on the internal screen it was very choppy. It could be that my problems stem from the imaging method I use to put Windows 10 on the external drive. I am using imagex which isn't supported for it, but I should be using these tools here https://msdn.microsoft.com/en-us/library/windows/hardware/dn916113%28v=vs.85%29.aspx edit: nevermind about the NVIDIA control panel. I looked at my Windows 8 setup which does have optimus enabled, and Intel Iris is connected to Color LCD there too.
  14. Has NVIDIA mentioned anything about Windows 10 and Optimus? I would like to use the retina screen since my external monitor isn't great.
