2012 15" MacBook Pro Retina (GT650M) [3rd,4C,Q] + RX 5700 XT @ 10Gbps-TB1>TB3 (Razer Core X Chroma) + macOS 10.15
Thank you all for the great help!
- MacBook Pro Retina 15" Mid 2012 “MacBookPro10,1”
- 2.3GHz Quad Core i7
- 16 GB DDR3 1600MHz
- Nvidia GT650M 1GB dGPU / Intel HD 4000 iGPU
- macOS Catalina 10.15.5
- Razer Core X Chroma
- Sapphire Radeon RX5700 XT Pulse 8GB
- Apple Thunderbolt 3 to Thunderbolt 2 Adapter
- Apple Thunderbolt Cable (2.0 m)
- Samsung S27C750 27" Display (connected with HDMI cable)
- Assemble Razer Core X Chroma with the RX5700
- Disable System Integrity Protection (SIP) in Recovery Mode (hold cmd-R while booting)
- Install and run purge-wrangler and setup the eGPU (don't connect the eGPU yet! See note below)
settings: AMD, no legacy, no ti
- Install and run purge-nvda and run eGPU Optimizations for AMD eGPUs
- Connect eGPU with Macbook Pro via Thunderbolt cable and Adapter
eGPU is recognised but the external screen may stay black
- If the external display stays black disconnect and reconnect the HDMI cable
The system halts almost immediately when connecting the eGPU before running purge-wrangler!

- Geekbench 5.2.0 Tryout for macOS x86 (64-bit)

This seems too low (even with the "prefer ecternal GPU" option was checked before launch)
- Unigine Valley 1.0
- Basemark GPU 1.2 High settings
Metal Score: 5475
I couldn't run it on the external display so it ran at 3840x2160 on the Retina screen…
Out of curiosity I downloaded and played Alien Isolation and Mad Max from Steam:
with the graphics settings maxed out in both games (except anti aliasign in Mad Max) they run smooth like butter!
It’s incredible to play games like these on a 2012 Mac!
- Works surprisingly well for gaming (see comment above)
- I still have to get behind the low scores in the benchmarks
- Hot plug and unplug works
- purge-nvda quirks:
Sleep mode and brightness control of internal display don't work (uninstall purge-nvda to bring them back)
Internal display does not switch off in clamshell mode
@torete, I didn't try the ethernet port but I hooked up a keyboard a mouse and a DualShock 4 (via USB) and they work flawlessly… It's like having a docking station (macOS Catalina) with just one cable.
