macOS 10.13 High Sierra - Compatibility

Just picked one off of Ebay $119.75..

Free shipping too !

Off chance do you live in the middle of the US or west coast?

Just asking not stalking,.

At 66 I don't even walk or eat fast, been told if I walk any slower I will be walking backwards !

LOL. No problem, I'm in the northeastern US. Sounds like you got a good deal on a card!

I'm in the midwest and have an extra stock card I can lend out if anyone needs it.

Nope not a wild-@ss guess at all.

Been seeing some writings about using the firmware a weird way to say the least ! Of puting malware and who knows what thru it ?

Yes ! Me too, near Rochester NY.

Might be the 1333 MHz DDR3 ?

I run the 1066 MHz DDR3 4 x 3 and a 1 GB, never got around to replace the 1 GB.

Bought mine thru Mac sales aka OWC.

Excellent! Glad to hear it.

I have apple certified Graphics card from Sapphire HD 7950 white one. I am still having issues with firmware upgrade.

Seems silly to buy an older version card just to do an upgrade to new OS.

I have had the same thing happen with the Mac Pro 5,1 (Mid 2010) Firmware many tries even got Apple Support involved. Was finally told to go to an Apple store closest to me. This is 40 to 50 miles round trip, then go back to pick it up. Have not called to find out the cost of the shop work ?

Wrote back to the support person and tried to sound halfway human, without getting higher on the volcano scale!

If the computers that are listed are compatible for High Sierra, then someone did the install on those computers or is that just a aside. Blowing smoke again ! Maybe I should go drop some iPhone 8's to let off the magma pressure?

Reminds me of the Apple and Power Computing wars ! Get more speed and then cleave you off !

If you are using a non-EFI PCI graphics card, that is your problem. For whatever reason, the firmware update requires a EFI card (Apple-spec ATI 5770, etc). I had to swap my NVIDIA 780 out for my old 5770 for the High Sierra install, then swapped it back. All good now.

Hello!

I have a MacPro same as you, and when I Update (the firmware) it start over again and again. After meny times startup suttenly it works. I thing that the firmwareupdate update one part a time and next time part two are updated. It a thought, but so I saw it.

Now I get a problem with my wifi network. The module don't exist? For some time ago it was the same, and a update from apple fix it automatic. So I hope that will happen again, before I go further. Until then I use net cable.

Happy Christmas
