Is there a big difference in what eGPU Enclosure you use?  

I went for Sonnet Gpu-550 W-tb3. Works well, but I want now GPU what don't need purge-wrangler

Is there any list what GPUs would work out of box with older Mac? I don't need to install purge-wrangler or any additional software. GPU will be recognized by mac.

I have MBA 13" mid 2013. Sonnet eGFX Breakaway Box GPU-550W-TB3 + Asus RX 580 8GB. Works fine, but I have install purge-wrangler and disable Vault. 

@andu, i have the sonnet and love it, either of those should work fine though.

@odin, You are running it on Windows? I am running it on Mac OS.

Macbook Air  13", mid 2013 (macOS Catalina 10.15.16)

@andu, I don't see why that would matter.

@odin, Yours runs without purge-wrangle? what GPU you are using?

I mean out of box. just connects and works.

@andu, I don't use my eGPU on my MacBook, only my Gram 17. But you said you have an RX580 in the OP, why do you need purge wrangler for that doesn't a 580 have native support in macos?

@odin, Maybe because I have ASUS RX580, not some other company GPU like Sapphire or because I use old mac with over TB 1.  But it did not recognized a eGPU without purge wrangler. 

I think only few company RX are working out of box with mac.

Not unless you use MVC’s flashed GPUs but I don’t know if they work on Catalina. PurgeWrangler doesn’t distinguish between GPU AIBs - only the chip matters. This should be clear/obvious from the documentation for it.
