If you have problem with acceleration I recommend this topic. For me it's working perfectly (but only on external display)

YES ! YES ! YES ! YES ! Thanks @Hedge it's finally working ! In my case this pieces of code paste in the terminal after use automate-eGPU scripts do magic ! Extended monitors plug into RX480 works fine, with acceleration, it also resolve problem with my software (resolume arena 5). Before using script it say there is a problem with graphic card ... and crash. Now it WORKs fine ! My setup is: -Echo Sonet III D -Asus RX480 4G Dual -MBP15 (mid 2015) Thanks one more time !

Hello. I just try to get work my first eGPU, and unfortunetlly i have a little issue. I use Sonet Echo III - D TB2 and Saphire Radeon RX480 Nitro 4g. I just install fresh system (sierra), have plug-in everything, but my system doesn't see the graphic card. In "This mac" ---> system report ---> PCI there is an information "An error occurred retrieving information about the PCI device." Finally I was found automation script, and my macos found rx480 BUT, computer start working terrible SLOW. I don't know what's going on ... when i plug-out my eGPU computer still working as like he have 20 years old. I have iMac 5k (late 2014). Please, any help ?
