  1. I have same issues with my set up. I think Netflix may require an HDCP handshake to enable 1080p playback on Macs. Safari is the only web browser on Macs that is compatible with Netflix 1080p, so tough to tell if it is HDCP or just the browser, but 1080p playback works fine on my other computers with standard GPUs.
  2. One thing to note, from what I have found, NVIDIA did not include DisplayPort implementation in the original specifications of the Geforce GTX 750 Ti hardware. See "Standard Display Connectors" at GeForce GTX 750 Ti | Specifications | GeForce . I think pushing 4K resolution via DP on the EVGA cards is problematic because it was not originally intended by NVIDIA and therefore not fully supported by their drivers. I don't know if you are using that connector for 4K output, but I switched to a GTX 970 and the setup has been very stable so far. Hope that helps, Pani
  3. That's good information! I agree that if we both are experiencing this it must be the driver or possibly the Akitio box, but that's less likely as it sounds like others have used it to power cards requiring >25W. Anyway, I got tired of dealing with this and since I have the DA-2 already, I bit the bullet and bought a Zotac GTX970. So far so good ... I'm running it in HiDPI mode obviously. We'll see how things go. I also have to figure out how to route the cabling into a closed box. A 6pin PCI-e splitter with low profile connectors would probably do the trick. I've been in contact with the manufacturer who made the harness that others purchased off of eBay, so maybe they'll be generous and make me one!
  4. That's correct. The card is an EVGA Geforce GTX 750Ti SC with TDP of 60W.
  5. Another update... I hacked up a wiring harness and powered the Akitio box with a Dell DA-2 PSU, but unfortunately I'm still experiencing freezes/kernel panics. After going through 3 PSUs, I don't think the problem is related to external power. I don't really know what else I can try at this point, but I'm open to suggestions! Thanks, Pani
  6. So I tried another external PSU (12V 10A) and still had problems. Kernel panics with web browsing and even simple OS tasks, so I'm starting to think that PSU power isn't the issue. Either there is a driver problem or the power output from the Akitio's PCI-e slot is insufficient. I wonder if others have had problems like this? Or is it because I'm running a 4K monitor and identifying a limitation of this setup?
  7. Thanks for your help Dschijn! I wonder if this cable would work. http://www.amazon.com/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W/ It probably would need to be modified to switch on the DA-2, correct? The benefit, is that it give me opportunity to upgrade to a more powerful GPU card if desired.
  8. Aren't they all made in China . I was concerned about getting a quality PSU, so I bought one from Amazon for $50. It seems to be of reasonable quality. It is 17.5 x 7.5 x 5cm. When I measured the output at the barrel connector with my very simple multimeter, it read 12.35V without fluctuation. So I'm not sure what else to do. Do you think the issue could be between the EVGA GTX 750Ti SC vs GTX 750? The total power draw on the 750Ti is 60W vs 55W for the base 750, so I would not expect the extra 5W to make a difference if the Akitio is indeed delivering 75W from the PCIe port. Also, I do have access to a DA-2, but don't have the skills to put together a wiring harness otherwise that may be a better solution. Any other suggestions? Thanks for the help! Pani
  9. Hi, Any thoughts on continued kernel panics with this setup: 2012 Mac Mini running Mac OS 10.11.1 (El Capitan) Akitio Thunder2 PCIe Enclosure 12V 10A 120W power supply connected directly to Akitio via barrel connector EVGA GeForce GTX 750TiSC I restored the kexts and removed all the drivers from my Time Machine backup, then performed a clean install using goalque's script. The install went smoothly and the eGPU was recognized immediately after rebooting, but I'm still am having problems with kernel panics. Also, despite reports to the contrary, when I re-enabled SIP, the kexts for the eGPU did not load. The eGPU was detected by the machine, but was just listed as "Display" in the System Report." Once I disabled SIP, the eGPU was again fully recognized and sent signal to the display. Anyway, I'm still experiencing kernel panics despite my hardware being similar to many other who seem to be running without issue. That being said, I am using the eGPU to drive a 4K monitor (LG 31MU97) via the display port connector, so maybe even with the supposed 75W from the PCIe port it is not sufficient? The following kernel panic occurred while I was running the Valley Unigine benchmarking app. Prior to this I watched several 4K videos on Youtube which were displayed smoothly and without any OS freezes.

  11. Hey everyone, Thanks again for all of the help. I have been able to get my set up working (listed below) and even have been sending 4K signal to my monitor via DP!! I had a couple of questions, however. 1. When booting I no longer can see the boot screen with the Apple logo. The first output the display receives is the desktop background. Is there any way to get the boot screen back? 2. I disabled SIP in order to allow goalque's script to modify the kexts. Is it safe to re-enable SIP after the installation is complete? I would obviously disable it again if I needed to re-run the script. Thanks! Pani 2012 Mac Mini running Mac OS 10.11.1 (El Capitan) Akitio Thunder2 PCIe Enclosure 120W 12V 10A power supply connected to Akitio power input EVGA GeForce GTX 750 Ti SC
  12. Wow! That was the issue. I can't believe I missed that! Thank you so much for your help! I switched the power supply to the one included with the Akitio enclosure and now everything is working fine. I will likely need to find another 120W AC adapter that delivers 12V to ensure the eGPU receives enough power, but at least I know all the components weren't damaged!! Thanks again!!
  13. Hi Everyone, Thank you to goalque and everyone else for the amazing support and information. It is really fun to take on a project like this. That being said, I'm having some trouble getting my eGPU set up working. The hardware is as follows: 2012 Mac Mini running Mac OS 10.11.1 (El Capitan) Akitio Thunder2 PCIe Enclosure Lenovo 120W power supply connected directly to Akitio EVGA GeForce GTX 750 Ti SC I was able to get everything connected fine and installed the drivers, etc. using goalque's script. Everything appeared to run smoothly after disabling SIP, but now I am unable to get output from the eGPU when I connect my external display. As you can see in the pictures, the eGPU is detected (although it does not list the specific model) and the NVIDIA software manager is running, but I only get the display signal from the internal GPU. When I reboot and connect the eGPU, the display says that it is not receiving any output. Any help or thoughts would be greatly appreciated. Thanks in advance! Pani
