darwin86

Hi guys, So after weeks of testing I can summarise: * OS X works perfectly and boots every time by using the method of power on, pause at boot menu (alt), turn on eGPU then continue * Windows on the internal SSD will not work, in any edition. * Windows 8.1 UEFI installed on an external HDD will boot with varying lengths of boot time - the DSDT override doesn't seem to be necessary. On the whole, to use in OS X to boost the internal GFX and add more monitors it's a great solution. In hindsight had I to do it over again I'd have swapped the £250 chassis purchase for a half decent AMD FX processor and motherboard. The truth is for what I'm using this for a gaming PC build would have made more sense - I did it because I could. Many thanks David

If you're working without it that would seem to suggest we don't actually need it on the 2015 rMBP 13. varyl - I'll have a look over this and give it a bash tonight. Thanks!

Hi fella, I recently published a thread discussing the 2015 13" Retina - may be worth reading through: Many thanks David

So I just wrote a quoted reply to this thread which evidently went straight into $null :/ Long story short - external USB 3.0 HDD Win8.1 working reliably now. Will try 10 when I have some time. normansdog - did you apply the ACPI DSDT fix?

So further testing complete, fairly unusual results: Fresh Win10 in boot camp: Won't boot even with DSDT override after graphics drivers are installed Win8.1 in boot camp: Won't boot more than once after graphics drivers are installed So I tried another clean build of Windows 8.1 on a different external HDD - works perfectly. Testing continues.

Further to my last post, I rebuilt my Windows installation and performed the DSDT ACPI procedure prior to installing the eGPU. I've had it reboot 5 times now and come up every single time - as Varyl says with varying loading times. Whoopee! I'll post more information after a few days of testing. Right now I'm using Windows 8.1 on an external HDD. I'll boot camp Win10 and see if I can get that working properly.

Hey Varyl, My results are very, very different from yours. The DSDT override is potentially the reason why. In Windows 10, I can get device manager to see the eGPU (first connection, no drivers) however the driver install procedure never completes and the OS goes haywire with processes freezing. Windows 8.1 actually allows the install and very, very rarely (no common denominators identified yet) boots up with the eGPU accessible. I tried bouncing it with closed however same results - on the rare occasion it would actually chime I'd sit for 10 minutes+ waiting with no joy. I'm going to do the DSDT override and see if that corrects the issue tomorrow. Many thanks David

Hi all, I've been following and reading this forum for weeks planning my big build date. Last week my kit arrived and the setup is now done, as follows: Akitio Thunderbolt 2 PCI Express Chassis (Not powered directly from supplied PSU, all power from Corsair supply) Corsair VS550 PSU EVGA GTX 970 (1 DVI monitor, 1 HDMI monitor) PCI express 16x riser with molex MacBook Pro 2015 Retina 13" (i5, 8GB RAM, 256GB SSD - 1 monitor connected via DisplayPort to VGA adapter - this allows me to clamshell the MacBook whilst in OS X) Unfortunately the somewhat "plug and play" experience most users seem to get from earlier generations is not what I have encountered. Ironically OS X was a doddle however Windows is a whole other kettle of fish. By installing automate-egpu and the Nvidia web drivers I can get to OS X and use gaming reliably by plugging the Thunderbolt cable in as the chime occurs and Apple icon appears. If the chassis is plugged in when the MBP is turned on it'll only boot successfully 10-20% of the time, the rest the screen stays blank and no chime is heard. So I have my GTX 970 in OS X which is great; however as you all know any kind of serious gaming has to be done in Windows due to lack of OS X ports. I installed Windows 10 via bootcamp (and later using VMware Fusion with the physical disk mounted as a VM) both instances the OS will start and when I hotplug the eGPU it sees a GTX 970 however when I install drivers and reboot the OS will never boot. It gets permanently stuck at the boot splash with a pending load. Later I installed Windows 8.1 to try that instead however despite a couple of successes (absolutely no idea what variables caused it) last night, I now can't get into Windows 8.1 again. I donated to receive a copy of eGPU setup 1.3 however from any documentation I've found this seems to only benefit MBR/legacy users. This generation of MacBook Pro is UEFI exclusively so not quite sure how to proceed. On the bright side I do have World of Warcraft running in OS X at 1920x1080 with every setting at ultra including AA and post AA. It looks stunning and is very reliable, running for several hours. My CPU temps are far lower than before too. Anyone have any suggestions? Many thanks David
