Have you had an issues with two card daisy chained. Also are you on 10.11.6 currently. I am trying to do a similar set up with 3 cards and 3 Akitos on a Mac Pro 2013. Hopefully it goes well. Any advice would be appreciated. Thanks.

Hello, I am having an issue with connecting 2 or more GPUs to the mac pro 6,1 with 10.11.6. Essentially I have a MAC PRO 2013 — thunderbolt Akito — Amfetec PCI Host card — Amfeltec PCI backplane — (2) 980ti. When I plug in the first 980ti, works fine. Second 980ti, doesnt boot. I used the script from this site and it worked fine for a single card. Any thoughts? Been going nuts.

Has anyone had successful luck with doing 2 980 ti via thunderbolt? I have 1 980 ti hooked up via thunderbolt with Akitia thunderbolt bridge. It works pretty well. It isn't as fast as if you have it direct connect with PCI to motherboard. I am using a Mac Pro 2013. However many many thanks to Goalque and the team. had to reinstall the OS, but then the script worked like a charm.

Hello, I installed the CUDA drivers and the web driver. (using nMP, 10.11.2, Nvidia 980 TI. Followed the terminal instruction and got this. Any thoughts?
