Same here in 3,1 hacked to run Sierra and High Sierra.  RX460 works fine in Sierra but not with High Sierra (up to beta 3) and not even with a helper card (ancient HD2500 XT).

I'd bet money that NVIDIA isn't going to write a video driver until Apple buys their chips to go into a system that needs a video driver (i.e. the iMac Pro or modular Mac Pro).

The driver's already been written, it's in beta status.  There's no reason to think this feature won't be added.  Look for it when High Sierra goes live would be my bet.

I'm in Kyoto, 37°C in my garden today !  

I'm jealous that you're closer to Akihabara than me. The best option I have for bargain hunting is "Den Den Town " in Osaka but even that's over an hour away by express.

Have you got your R9 270X showing bootscreens ?

If so, on what ports ? Using any adaptors ?

Same as you.

What's your Mac Pro setup ? ( you should fill out your profile in your forum settings. )

EDIT : Have you tried using Netkas's script ? ( no pain, no gain ).

Hello!
I've been using Windows on my MBP to get my AKiTiO Thunder3 external GPU to work, and waiting for MacOS High Sierra to show up to get my eGPU to work, installed it and turns out it doesn't work... Been waiting, all betas, this is the 3rd and still nothing. So looking around found that KhaosT & Netkas figured out this patch, downloaded right away, disabled SIP, went back and when trying to apply it, it didn't work, of course; with my excitement I didn't even realize it was for 10.12.x only... I tried to "forceApply" after reading about it, but still nada. So it seems Apple is keeping supporting for all eGPU cases and devices "in jail".
Do you guys know how to "fix this", or have any plans to get this patch to work with MacOS High Sierra too?
Thanks!

I just discovered that my R9 270X is showing bootscreen on the Display port to HDMI adaptor !  I expected that DVI to DVI would be the bootscreen. Live & learn. I bought the DP to HDMI adaptor two years ago on a whim .. I'm glad I kept it now.
EDIT : DP - DP to HDMI adaptor - HDMI Bootscreen OK if only ONE monitor  connected.
                    Same with DVI - DVI ifonly one monitor connected.


Also checked it in Sierra 10.12.5 for Metal support and it's OK

Please post the rom you made.

vinnie1978

Thanks so much for your reply . . .  I actually knuckled down and boned up on Terminal commands and using "Bundle2" ( upgraded "bundle" ) targeting the " efiromheader_7950.rom " and working in Terminal in 10.6.8 ( my favourite OS X personality ) .. succeeded !

I flashed in a dedicated Win7 HDD on my cMP ( I don't like Bootcamp ) using AtiWinFlash.

I used Hex Fiend to edit the two incidences of " 7950 " to " R9 270X ".

 I have the R9 280X booting efi with the correct name in Sys Info  and running two monitors; One from DVI - DVI ( lost the top DVI port ) and another monitor using a Displayport to HDMI adaptor.

I'll post some pics in this thread in about 30 minutes.

I got this card here in Japan for ¥6,900  .. roughly US$60.

The card is reference but no bios switch like the MSI version. It comes overclocked to a base 1030Mhz  - to 1080Mhz in boost mode. Here is the card http://www.kuroutoshikou.com/product/graphics_bord/amd/rd-r9-270x-e2gb_oc/


( I also have this company's 2 port USB 3.1 PCIe card with Asmedia 1142  running in my cMP 4,1 flashed to 5,1. I got it for ¥1,400 !  It works brilliantly beside a 4 port Inateck FL1100.

Success !  My R9 270X 2gb  is now EFI booting but thanks to Netkas & whomever created the upgraded "Bundle2" ( searched but now can't find him ).

Working :

1. Displays "R9 270X" in Sys Info. ( Edited the rom with Hex Fiend changed incidences of "7950" to "R9 270X" )

2. Bootscreen in bottom DVI to DVI.

3. Bootscreen if using one monitor Displayport to HDMI adaptor to monitor HDMI input.

4. With two monitors connected the DVI - DVI is first to show bootscreen then the DP to HDMI adaptor kicks in.
    I have yet to try with a dedicated Display port to HDMI cable. I'll buy one soon.

5. Oceanwave full screen AA shows 62 fps  - enough for my needs

Not working.

5. Upper DVI

6. HDMI to HDMI ( worked OOTHB before being flashed )

==================

This R9 270X is made by a Japanese company that is always cheaper than the big players. I got it for about US$60 ( I live in Japan ).
This is the website for my card http://www.kuroutoshikou.com/product/graphics_bord/amd/rd-r9-270x-e2gb_oc/

EDIT 1 : Next project will be to find the R17 resistor!

EDIT 2: On the back of the card I found a WHITE TEXT  list showing R16 & R 17 in an outlined box with an upper case "A" listed perhaps as a resistor group location map ( no idea yet )  but after checking both sides ( with fan removed ) still can't find R 17. I have no idea what the WHITE TEXT signifies .. I'll Google for info but any advice very welcome.
