Barefeats has posted part 3 of his test with our new "Just Works" eGPU cards.

He found the iMac Pro to be a little more trouble than the TB3 MacBooks.

We will need to get our hands on one to sort it out. But I can report that a 2011 iMac 27" with AMD 6970 works like a dream with the same eGPU cards. Both internal and external displays work and you can easily move objects from one to other with no jitter or lag.

I was also able to connect a 5K and a 2nd 1080 to the iMac. Odd that this AMD dGPU gives no problems but newer ones do. Had iMac on left, 5K in middle and 24" Apple LED on right. I could have handled air traffic control at LAX with all the screen real estate.

Here is the thing with doing these cards. Each and every Mac variant acts slightly differently with eGPU. We don't have (and won't) one of every Mac. SO we will start selling the cards targeted for the machines we know they work well for.

So first batch will be shipping 2nd week of June if all goes as planned. They will be for nMP 6,1, TB3 MBP 13" with no Touch Bar, 2011 iMac with 6970, and 2014 Mini. They will be tested in 10.13.4 and possibly 10.13.5 Beta. We will do a limited run of 10 or 20 to sort the customer service issues as they will likely require more of that then the cMP cards.

The cards most likely work well on other Macs, and we look forward to reports from owners who try on other Macs. But we can't promise what we haven't tested. 

We will discourage owners from running any of the hacks, cracks, and scripts from the interwebs with our cards. Not needed and more likely than not will cause issues.

And realize that an OS update or driver update may BREAK the cards support. So don't run any without checking here first. And once we have a fix, please be patient about us getting it out to you.

It is a daunting prospect to sell these cards, we need everyone to help us make it possible. This includes not leaking our work on those same interwebs. 

Also, if I can figure out how, we will add a eGPU forum for our customers as their needs won't be addressed at other Forums where folks don't have EFI magic making eGPU effortless.

Here is latest test from Barefeats:

As I am booting Macs a couple hundred times a day I started to get sick of seeing the CUDA Pref pane always pop up on desktop.

Whether I need an update or not, I don't need the clutter.

I found this nifty terminal line that makes it stops bothering me.

rm -f /Library/LaunchAgents/com.nvidia.CUDASoftwareUpdate.plist

​And next boot you'll only see it when you invite it to your desktop.

Thanks to rgov at Nvidia forums.

,Barefeats.com continues to trumpet our success with these cards. Please read the tests and consider clicking on the various links to his vendors. Many have been with us since PowerPC days and deserve support.

So, here is where we are. We have cards 99% ready for nMP 6,1 and Mac Mini 2014, and MBP 2016 TB3 with no touchbar. These machines all work perfectly with our current eGPU cards via EFI. It is likely that other machines with no dGPU will work well. Buying up one of every Mac TB system will take us time & $$$ to support. If you want true and useful eGPU support, help us bring this to the world.

You put our eGPU EFI card in a suitable chassis and connect via TB. You boot and hold "Option" key and see what OS's are available. Choose and boot. While nobody else on the planet has gotten a 6,1 nMP to boot Windows 10 via eGPU, our cards do it with the greatest of ease. It is an awesome VR development platform.

Proven at Barefeats.com. 

So, for 10.13.4 on the above systems, you are able to boot an eGPU without the myriad hacks, cracks, scripts, and mods needed via the "enthusiast community". You just plug the card in and boot. EFI on card works the Win 10 or OSX boot. Displays work and you get to work creating content, not experimenting with code kiddie scripts.

On iMac Pro we understand that external display works but internal will require further development in OSX. (Windows already perfect) If anyone in LA/Hollywood area wishes to help, loan us your iMac Pro and we will continue development on this.

We can do demos of eGPU with nMP 6,1 and working VR in Windows. Did a demo at UCLA last year with perfect results. The nMP 6,1 will be an awesome VR development platform, now.

For the mentioned systems we will have cards for sale by June 15. Pre-sales by June 1. We will likely offer GTX1080Ti first as eGPU. 1080s may be next followed by others.

Please respect our unique work and long hours of development. We have had bad experiences before when our work went into the public realm due to disingenuous folks in the community. We need your support to make this work make sense for us. Prior bad acts delayed advancements for the whole community. (nMP 6,1 Windows support delayed by a year+ due to this)

​Support our work so we can continue to be the leaders in this field. If we are undermined again, we will stop work on this and community as a whole will come to a grinding halt.

So it appears that many iMacs with MXM cards are experiencing issues with dying cards. 

We are going to jump in and do something about this. To begin we will offer direct replacement AMD cards. But as soon as our nifty new (OK, old) 27" iMac with 6970 gets here we will be working on Kepler cards from Nvidia. These run cooler and offer better performance. 

We will  be curious what the ,market will bear. With help from our brilliant staff programmer (Netkas) we could offer Maxwell/Pascal MXM cards. Question is, will anyone pay for these? Value of a 27" iMac of this era is below what any of these cards cost as PC cards so we will have to see.

Our European distributors will be authorized to sell these cards too. (One in UK, one in Poland) Please let us know if this is a product you want.
