Hi, I have been reading recently about the possibility of a new 5k Thunderbolt display using Thunderbolt 3 but with an integrated GPU to allow it to be used with older macs with poor graphic capabilities. If this were true, then would we not see some sort of support for the eGPU in Sierra ?

Hi darwin86 - I did read somewhere that the rMBP 2015 did not need the rEFInd mod - I think it was a comment by goalque. My setup does work - but boots somewhat unreliably into windows. It may though have something to do with windows wanting to install millions of updates at each re-start - I have now disabled that feature and had 2 good starts (the mac belongs to my daughter so I can only get to run tests when she doesn't need/want it which makes the whole process rather sloooow). btw I am running a 980 card not 970.

I hope that the development continues - just remember DOS was mostly bought for nothing by Gates made into a royalty fortune - Gates then proceeded to lobby for software patents in order to pull up the ladder behind him. Death of innovation.

Hi, I discovered this forum via the link from the Bizon site, and have in the last hour read a lot of fairly strong criticism of Bizon and the product. I would just say that setting up a business requires a lot of determination and effort which should be applauded rather than criticised. I run an engineering business and technology is only 20% of the product, the rest is organisation, structure, money, sales, luck and sheer determination. Why not look at Bizon as an opportunity, if you can develop software that will make the eGPU run reliably with Mac hardware then just do it and I for one would be happy to buy it from you. I am an electronics engineer but I do not have the time to delve into the depthd of drivers for all of this hardware, and I would be more than happy to pay money to avoid having to spend the next 6 weekends 12 hours a day learning how Thunderbolt works with every possible version of Windows and mac osx. So, people like you do the software, people like Bizon set up the business and people like me with money but no time, buy it. Thanks for the work so far, I hope you continue!

Yes, I see that now - although they do credit this forum for the information - which is how I found it.

Ah, I see what you mean.

Hi darwin86 - it doesn't appear to be the same thing - where can I find the fabled ACPI DSDT fix?

Hi, I have the same hardware (Retina, 13-inch, Early 2015 + 970) and Bizon say that is this not stable which I can confirm. As I say, it works fairly reliably on OSX but Windows has been tricky. When it boots then it works fine, but it has been tricky to get it to boot reliably. Some seem to have managed it, I am still working on it. On balance it was worth the effort and money, but you have to expect some problems. 10.11.6 2.7GHz i5 8GB

sorry - I am not sure what you mean by "System version"? Bizon or Mac or...?

hmmm not sure - I downloaded and ran a script from Bizbox which may have done the same thing - I will check.

Hi, I have the Bizon box 2 but with a macbook pro late 2015. The system is not stable although it does work. From Bizon I see this... iMac 5K Late–2015 (AMD Radeon R9 configurations only) OS X: No external display output. Able to work as a CUDA accelerator (Adobe Premiere: up to 6X performance boost). Windows: Graphics card detected issues (error 12). If you bought the box from Bizon then just contact technical support, they are extremely good and very helpful (IMHO).

I think (but do not really know) that if you have a discrete graphics chip / card in your Mac as well as the integrated intel then the eGPU will only ever work on an external monitor.

Ah, having said that, I just finished the windows update marathon, restarted - waited for 10 minute while the spinning balls rotated and lo and behold, win8.1 running on the external monitor and the eGPU working fine. Who knows. I am afraid to turn it off!

Hi I have the same issued running win8.1 on an external USB 3.0 SSD - it worked initially bit then after a couple of reboots stopped working. There was a big windows "update" in there somewhere so perhaps that didn't help. The guys over at Bizon box seem to think that the 13" 2015 macbook pro is simply not compatible with an eGPU - seems to be unstable. I wonder whether this problem can actually be solved with this hardware. OSX runs fine with the 970 - Windows simply will not boot.
