Any current card is incredibly better than the GT 120 that you have. RX-560 is half the price of the RX-580, but the latter has better macOS support, have HEVC hardware decoding with Mojave, probably we will get hardware encoding working too.

RX-560 have some driver support problems with 10.13, RX-580 had only with 10.12, none with 10.13.

RX-560 do not need supplemental PCIe power, RX-580 needs a dual miniPCIe 6-pin to PCIe 8-pin cable.

Hey mate. I installed the card but it looks like I need a power cable. Front page of the booklet says you need power. I'll have to go tomorrow. Do you know if a standard 6 pin to 8 pin pcie cable will do? I'll get googling. Thanks AGAIN :)

OK had to order online so will have to wait. I thought in the meantime I could start the 5.1 flash process but you need OS Mavericks and that is even harder to find than the bloody cable :)

You don’t need Mavericks, just do a clean install of 10.11 and disable SIP.

Mate sorry for the 100000 questions. I'm trying the homebrew but can't get the download going. Sorry man, appreciate your help

First you install Command Line Tools, then home-brew, then mas. You have to be logged on.

sudo xcode-select --install

mas syntax is: mas verb MacAppStoreID

To install El Capitan:
Code:
mas install 1147835434

If you already signed with the Mac App Store, no need to re-sign, mas uses that.

I get this error. Looks like I'm not logged in

Test your Mac App Store app, check you don't have to accept terms or something with your account - with iOS12/Mojave release Apple changed the terms.

OK so I tried on my old macbook pro and this time the store opened and asked for my password. That went ok but then it said I can't download as it's not available for this ID or was refunded or returned. So I guess I never downloaded it in the first place back in the day.

Hey. Just wanted to update you all. I went down to Mavericks, flashed to 5.1, updated to High Sierra and in that process updated my firmware. Yesterday my mini 6 pin pcie power cable came and my Radeon card is up and running. Tonight I plan to update to Mojave.

Thanks for all your help, really appreciated. Have a great weekend
