I have just purchased a used HD 7950 3gb OC. It was used on a PC can I just plug it into mac pro mid 2010
Can you boot to the EFI screen ?
Good Morning
As I have said earlier my Sapphire 7950 card is working albeit seems a little slow. I get all the normal things like the start up screen etc, I now have macOS Mojave 14.1. The little spinning circle with the rainbow colors seems to be popping up a lot in Photoshop. Is it just the algorithms working or is my computer just slow?
EFI screen is before computer boots into the OS. Basically when you press and hold 'Option' on your keyboard you can choose a startup disk for example and it shows on the screen.I don't know what you mean by the EFI screen but it boots up with the apple logo, Then comes up with the Mohave screen, enter password and I'm off and running. Has a resolution of 6720 x 3780, However UI 3360 x1890 connected via display port. The DVI port appears to to be the No 1 port. But I'm happy
Hi
Am I missing something. Do I have to flash the 7950, even though it works with the apple logo etc. It seemed to be plug and play
[doublepost=1543470534][/doublepost]Hi again
The 7950 I have is a PC card, but seems to work ok. but I'm not sure if it working as Pcie 1 or 2, can someone pls help
I used this video and the text below it in YouTube app to flash my 7950. Really easy procedure. After that I have EFI boot and I can choose between Mojave and windows 10I've got two DP1.2 4K 60Hz displays connected to my 7950 full time. I'm on 10.13.6 and it boots fine, w/ no EFI screens. The trick is to leave it in PC ROM position on the switch. In the Mac position it cannot boot, locks up. High Sierra updated the boot ROM, so I don't expect much trouble upgrading to Mojave. Am I being over-optimistic?
Then Shut down and because your 7950 ( or 7970 ) has a BIOS switch . . set it to position "2"
The BIOS switch can be a lifesaver, I wouldn't buy a 7950 / 7950 which didn't have it but you are correct not all 7xxxx cards have the BIOS switch. Merry Xmas
