MacBook Pro (Retina, 13-inch, Early 2015,) [2C, i7] + SAPPHIRE NITRO Radeon RX 590 8GB GDDR5 @ 16Gbps-TB2>TB3 (Razer Core X) + MacOs 10.15.5
Macbook Pro (Retina, 13-inch, Mid 2015)
MacOS Catalina V. 10.15.5.
Memory 8 GB 1867 MHz DDR3.
Razer Core X enclosure
(Apple) Thunderbolt 3 to Thunderbolt 2 Adapter
(Apple) Thunderbolt 2 Cable (2 meters)
SAPPHIRE NITRO+ Radeon RX 590 8GB GDDR5
I used Purge Wrangler to be able to install the eGPU using the Razer Core X. The patch installation went very well and the system identified the card right away, and it seems to somehow operate ok while it is not under heavy load. If I run Heaven benchmark (ultra) for example, or use Twinmotion (3D architecture platform / ultra settings) the system will freeze or restart after 10 o 15 seconds. The laptop will also crash if I want to restart it with the eGPU plugged in. I often gets the black screen w/ "Your computer restarted because of a problem. Press a key or wait a few seconds to continue in a few seconds" message.
I have researched a lot online and was not able to find a solution. I did come across a post in an Apple forum where the conclusion was that the Macbook Pro early 2015 is simply not compatible with the Rx 590 when using the Thunderbolt 3 to Thunderbolt 2 adapter. I am not 100% sure this is the case,
@itsage - do you mind taking a look at my setup/issue?
