Hi there!

First, thanks you all that contributed to this great forum! I've been doing a lot of reading to be able to use an eGPU with my Macbook Pro and a 32" 4K Benq external display.

This is my current setup:

I can't get the external display to work. My computer detects the eGPU, but that's all:

I don't see the eGPU on the menu bar either. I see many users here struggle with the same and fixed it reseting the PRAM. I've done that a couple times, but still...

 

Any advice? Thanks!

@traste, It's most likely the XFX firmware is the culprit. You can try flashing a vBIOS from a different with the same VRAM. This can only be done in Windows.

That seems a really good explanation. However, I also asked on Reddit and they gave me another possible explanation. That card is not listed as supported here. RX550 seems to use the "Polaris 12" chip, which seems not to be supported by Apple.

Do you think flashing a different firmware worth a shot? Thank you

@traste, I misread as RX 5500 from the title. It's been a while since I checked if there's new changes to Polaris drivers. If your intention is to use the eGPU for external monitor out (limit dGPU noise and heat). I'd say to look for a used RX 460 2GB.

Thanks. That's What I'm going to do. I like the Razer Core X because of the power supply. But I don't actually need a lot of graphic power. My main problem is that the computer slows down to death when I'm on a videoconference. Really annoying for a 3K USD machine.

 

By the way, do I also need to pay attention not to buy a RX 460 with the XFX firmware? I guess I should buy this one, instead of this other one. 

 

Thanks!

@traste, For use in macOS, avoid XFX is best.

 

Thank you. I finally ordered a used Sapphire Radeon RX460 2GB.

I just wanted to get back to say thank you!

@itsage, I received the RX, plugged into the Razer Core X Chroma and that was all. Works like a charm and it seems my problem is fixed now. Although I hated having to spend an extra $400 for this solution. Thank you Apple! 😡

@traste, Good to hear you got the eGPU going. I agree it's ridiculous the dGPU in 16-in MacBook Pro can't handle basic tasks.

@itsage, Do you mind if i asking few related question? I'm curious to know whether

https://shopee.com.my/-GPU-AMD-SAPPHIRE-rx560-4G-DDR5-i.507849550.10425103262

This card suitable for the Razer X Chroma with my 13" Retina MacBook Pro Mid 2014? (Between i own the Razer X Chroma more than a year but i don't have chance to get a budget graphic card)

Also does it require to run Kryptonite and Purge Wrangler? I'm still new to this and also do a lot of reading but i can't figure it out to put on gamble on this model of the card. Also i read their compatible list for macOS, but they didn't stated the RX 460 but it does work for @Traste

So i would like to ask your expert opinion, with my setup and model MacBook, which Card i should get? I know the 470/480/570/580 it works but it's too expensive here additionally it's a USED condition. Can i get the 460/560 to work like a charm? And which sapphire brand only? Thanks and hear from you soon.
