Radeon Compatibility Guide - ATI/AMD Graphics Cards

Also, in display preferences, it would seen that my Dell U2715H monitor is being recognized as a TV. I cannot switch it to a normal 60Hz setting. The monitor is also set at YPbPr and not RGB.

Patch EDID to force RGB, see here:

Thank you, thank you, thank you!!! That finally worked! I spent 8 hours yesterday trying to edit a framebuffer when all it took was this.

Shocking that this (or similar) issue has been around since before 2013 and affects real Macs as well!

Anyone know why this is an issue with this card (or others)?

I'm sure I could have done this with Clover injection somehow?

It's actually a problem with the Dell monitor. I've got an RX 570 by Gigabyte and use an LG IPS monitor. I've not encountered this problem. Apple uses LG panels it their iMac line.

I’ve been using a 27″ Dell at work for a couple years, connected to my Mac via DisplayPort. It’s a pretty nice display with a bright IPS panel, good colors, and wide viewing angles. When I plugged it into my new Mac, the text looked terrible.

Eventually, I noticed something in the monitor’s settings: My new Mac was connecting with an Input Color Format of YPbPr.

A few weeks ago, I bought a Nvidia GTX 1060, only to learn here that it will likely never work with Mojave, because Nvidia has been stopped from releasing the drivers by Apple.

Swell.

So, off to Amazon again, and I'm getting a Sapphire 11265-05-20G Radeon Pulse RX 580 8GB GDDR5 Dual HDMI / DVI-D / Dual DP OC delivered tomorrow.

But reading thru this forum (and others) has me totally confused. Some folks say to enable the internal GPU and others say to disable it. Some say to just leave the old 1060 drivers alone; others say to remove them; some say I need "Lilu and Whatevergreen" (I did find the iDiots guide here) ... and so on.

Of course this is because of different mobos, and different model Radeon cards.

I'm more of a user than a modder, but I'm not afraid of mucking about either. My primary software is Final Cut Pro and Photoshop.

What I'm hoping is that someone here who has made the transition from Nvidia to Radeon, and has the same mobo (GA-Z77x-UD5H) can offer me the steps I need to take to successfully use the new card. I'm also hoping that my old, simple mobo will make life a bit more simple, but whatever it takes...

Thanks... and happy holidays to all.

With that CPU and RX 580, I'm afraid you will not have much joy.
I have an i7-3770K + Z77X-UP5 + RX580 and FCPX is not vey stable.
With the latest Mojave release, Apple have removed h/w codec feature of the RX 580.
You will be able to use your system, but will rely on the CPU and IGPU as long as H.264 output is all you need.

See issues here.

ARRRGGGGHHHH!!

OK: thank you for saving me. I've got a return/refund approved on the card.

So: if I want to continue to move forward, then I take it I need to build a new hackintosh (or pray that Nvidia releases drivers?)

Any suggestions for what mobo/CPU/card -will- work with, and accelerate, FCP? I'm more a creative than a gamer...

Thanks again. Not the news I wanted, but I appreciate your response.

Cannot really make a recommendation (otherwise someone will go "ARRRGGGGHHHH!!" when it does not work ).
Do your own research first, don't just listen to folks who say "it's works OOB...it's fine for me...etc" as their usage and needs may be completely different to yours. Unless then can categorically prove (systematic repeatable tests) that it does what you need, then be vary of the claims. AMD RX580 is perfectly good GPU for the the GUI but has issues for encoding/decoding certain codes.

Vega seems to be better supported in terms of encoding/decoding.
But so are latest Intel CPU's + IGPU's. If you can afford it, look at latest i7's & i9's and latest Xeon's - specially the one's used in real iMac Pros.
Even on real Mac's, they use the GPU for GUI and rendering together with the CPU, and their own custom T2 chip for encoding.

I have come to a conclusion that I need to move to a newer system after the holidays.

Thanks. Sounds like sage advice. Like you, I've had good service and performance from my setup (which runs all day, just fine at 4.6) but as you say, perhaps it's time to move on. First glance, it looks like it will cost $1200 or so.

Anyway, thanks again. Good luck to us both!

Sorry about this, but one last question. Just rereading your comments and this struck me "With the latest Mojave release, Apple have removed h/w codec feature of the RX 580."

So, if Nvidia has stopped offering drivers and Apple removed the h/w codec in Mojave are you saying that there is basically No Way to use a hackintosh with FCPX moving forward? IOW, I need to go back to "real" Apple hardware?

There's no rush on my part, as I assume I can just stick with what I've got for a couple of years, but I make at least part of my living editing video... and etc etc...

Thanks.

There are workarounds (may be not ideal). Using powerful latest CPU's and very fast NVMe SSD's, will allow FCPX to use the hack without utilising the full benefits the AMD GPU.

Maybe if there's enough backlash from Apple fanboys who use eGPU's (with similar problems now), then maybe Apple will rethink and fix the s/w temporarily (before moving on in the few years time to their own fully custom chip).
