I am currently using the Amfeltec GPU Expander Chasis, in a Mac Pro 5,1 and it is working fine ... except ... I can't get the system to start up with more than 2 GPUs in the chassis. I've read it has something to do with OS X not recognizing more than 2 external cards. Currently I'm running 10.12 ...

Thank you @enricocerica ....

Holy crap!!! That Proxy totally worked! Thank you thank you thank you!! Turned on Offline mode at the same time.

Really appreciate it.

This must have something to do with the DDoS DNS attack. I'm in California and have the same issues. Can someone from OTOY confirm what's going on?
It was working fine earlier this morning. I can't log into my Account page off of OTOY's website.

Frustrating.

Okay - this is a bit excessive.

I ran out of credits on ORC, and have received over 270 emails telling me my render has been stopped due to low credit.

I KNOW!! I have no credits left!!

You may want to fix this feature. Oh wait - I thought the e-mails were over, but I just got another one ...
