Recovery with a RX470/480 (and obviously 460) works fine... mostly. My 4,1 tends to do extremely weird things if you try to move windows around (which seems to try to enable HW accel., which freezes). Network, so latest image.

Generally always wise to keep an EFI supported GPU anyway, if not for Filevault (no one should run unencrypted 2017) at least for recovery needs (who knows...).

Sorry, hope this not off topic, but what do you mean by "if not for filevault"? I'm looking for a new gpu and does that mean filevault doesn't work without a EFI GPU? Thanks in advance :)
 
You can - blind. With no guarantees that an update won't break it.

Filevault + no EFI GPU is as good as just forgetting the password.

Ah, I think I understand: you mean if driver support breaks, you won't be able to boot and then won't be able to access a FileVault protected drive?
I have a backup strategy that deals with these situations ;)
Or are there any other issues during normal use? Thanks for your help.
 
So for those who only have ssh access to a box, will the following work? (Managed to get GUI via additional old Nvidia GPU)

sudo nano /System/Library/Extensions/AMDRadeonX4100.kext/Contents/Info.plist # add 0x67DF1002 to IOPCIMatch
sudo nano /System/Library/Extensions/AMD9510Controller.kext/Contents/Info.plist # add 0x67DF1002 to IOPCIMatch
sudo LC_ALL=C /usr/bin/sed -i '.bk' 's@AMD R9 xxx@AMD RX 480@g' /System/Library/Extensions/AMD9510Controller.kext/Contents/MacOS/AMD9510Controller ; sudo mv /System/Library/Extensions/AMD9510Controller.kext/Contents/MacOS/AMD9510Controller.bk ~/tmp/
sudo /Applications/Kext\ Utility.app/Contents/MacOS/Kext\ Utility # wait a few minutes until it is probably finished, then control-c
sudo reboot

10.12.4 I wish. I can't even get my card to work properly in 10.12.3 yet. Everything seems Ok until I do something like wake from sleep and then it’s full speed fans, (not the GPU fan), (I have card in slot 1 with board power connector 1).
I’ll see what happens if anything in console next time I install it.

I haven't used sleep for years, so maybe that's why I've not had any problems here. I'm using an external power supply with the cables routed to the 480 card and just duct taping the side of the case on since it won't latch.

Know what. Took out the Gt120 and so far………so good.

That's true and a good point. Probably has to do with some graphical corruption I see from time to time here. Thing is, I'm scared to remove the nvidia card given the precarious situation with getting support going. Has anyone tried the shell enabling method I noted before? I guess I'm going to give it a shot here the first of next week to see if it works out, but was hoping to know if anyone had some input on that.
 
Man I hope so. Someone told me that supporting these cards has been requested of Apple so you might want to go put your voice into the bug tracker. It should be easy for them to do!

Is this in reply to me?

This might be a stupid question, but how do you tell if acceleration is working? Are there any visual cues?
You WILL know when you see it even if nobody tells you. What card are you running now?
A good example will be to boot into safe mode, IIRC that runs sans acceleration.
 
Beta 2 upgraded just fine with the steps noted above, including upgrading from the shell:

sudo softwareupdate -i -a

sudo nano /System/Library/Extensions/AMDRadeonX4100.kext/Contents/Info.plist # add 0x67DF1002 to IOPCIMatch
sudo nano /System/Library/Extensions/AMD9510Controller.kext/Contents/Info.plist # add 0x67DF1002 to IOPCIMatch
sudo LC_ALL=C /usr/bin/sed -i '.bk' 's@AMD R9 xxx@AMD RX 480@g' /System/Library/Extensions/AMD9510Controller.kext/Contents/MacOS/AMD9510Controller ; sudo mv /System/Library/Extensions/AMD9510Controller.kext/Contents/MacOS/AMD9510Controller.bk ~/tmp/
sudo /Applications/Kext\ Utility.app/Contents/MacOS/Kext\ Utility # wait a few minutes until it is probably finished, then control-c
sudo reboot

Thank you for update. Do you recall if doing macOS update this way was faster than through the App Store?

I've just updated from 10.12.2 to 10.12.3 using CLI softwareupdate and kext editing and all worked like a charm (RX480 is the only installed GPU on my system).
 
Anyone in here running a 460 at 4k?

Curious if it performs ok/well/good/great with 4k @ 60hz ?

Thank you for any thoughts!

Am I right in thinking that even if I update the usual way that the Mac will still boot, just without acceleration?
