Newb can't get it working...please help!
Hardware: MBP (mid-2015, Retina), Sonnet Breakaway 350w, AMD Radeon RX 580, Apple TB3-->TB2 adapter cable and Apple TB2 cable
System: Mojave (10.14.2), purge-wrangler 5.1.1 with Legacy AMD eGPU's/Ti82 devices/TB1/2 AMD eGPU's enabled
Problem: I can't get the Breakaway recognized/powered by the MBP. After running purge-wrangler, plugging in the Breakaway, rebooting twice, logging out and back into Mojave -- still nothing. I then uninstalled purge-wrangler and tried automate-eGPU EFI -- same result.
I've successfully used the Breakaway with a Mac mini 2018 and a TB3 cable. What else could I be missing? I can't imagine either the TB3-->TB2 adapter or the TB2 male-male cable from Apple are faulty, but I'm scratching my head trying to figure this out.
Thanks in advance!
MacBook Pro (mid-2015), 2.2 GHz Core i7 (I7-4770HQ)
Sonnet Breakaway Box 350w
AMD Radeon RX 580
