Well, the countdown for Hackintoshs has officially started. But we all knew that it was coming sooner or later (I even made a thread back then in 2016 - https://www.tonymacx86.com/threads/support-for-arm-chips-found-in-macos-sierra-kernel.203503/) Personally I switched to real Macs in 2018 and...

Audio over DP works for my Dell. I don't know how it behaves in enclosures though.

I just checked 2048x1152 and it's really not bad actually. Fonts are still sharp and readable. No pixels around font corners nor any fuzziness. I think you'll be happy with it.

The availabe options in the scale menu are: 1600x900, 2048x1152, 2560x1440, 3008x1692 and 3360x1890. I wouldn't go for any other option as 2560x1440, as it is exactly the half of the original 5120x2880 resolution and looks the sharpest and most readable by far. You can still adjust the font...

I can only speak for the Dell UP2715K, I run 2560x1440 hidpi at 60Hz with 2 DP cables, no problems. You'll have another problem with the LG 5K though, as it only has an thunderbolt-input. I don't know if there's a RX480/580 card that provides an thunderbolt-output. Multi-monitor is also no...

I don't know these bootflags, nevertheless they were not necessary in my case.

And this was because of APFS? I didn't read about any bricks because of APFS yet. Anyhow it's no concern for me, since I use a Time-Machine-NAS. About the other kexts: Well yeah, these were from previous installs on other Mobos. You probably just need IntelMausi. Lilu is required to work...

I made the switch to High Sierra 10.13 - RX580 and Dell 5K work out of the box with SMBios MacPro 6,1, Lilu.kext and Whatevergreen :clap: Success: GA-Z170X-UD3, Skylake 6700k, AMD RX580 (RX480), 5K Dell UP2715K, no helper card, almost OOB

First of all, this guide is for a completely new install. For whatever reason, the upgrade procedure failed from 10.12.6 to 10.13, I got a hangup at the Apple boot logo. So I said screw it and did a new install and restored from a Time Machine backup. So this guide works fine for a new...

Yes, when you use a bogus framebuffer or connect the DP cables in the wrong order, these hiccups with flickering may appear and stay for a while. Dell has this even stated on their official support page: Screen Flicker Flicker on screen may occur right after the symptom of split screen or...

I would, in the end, also not recommend buying this monitor. It's beautiful when it works, but getting it to work with a hackintosh is a real PITA and the circumstances and tweaks can change with any point release. It's definitely not for beginners. I would at least wait for High Sierra and for...

How do you do that? With WhateverGreen my RX580 works OOB, though without 5K support (Dell screen appears as two monitors) and Luxmark gives only 300 points. I have to test this again with a fresh install and various SMBIOS settings.

Dell doesn't support DP 1.4, you still have to connect 2 cables. 5K with RX580 and 10.12.6 isn't plug&play either. I had to remove the IDs 0x67DF1002 from AMD9510 and AMD4100 to force macOS to load the kexts AMD9520 and AMD4200 instead and use framebuffer Gueriba. That might change with...

Didn't work for my RX580, Sierra 10.12.6, SMBios MacPro6,1. Login screen fails to load. Having said that, I edited the relevant AMD kexts. With the default pair that Sierra chooses (AMD9510 & AMD4100), my RX580 only reaches 3000 points on Luxmark. I removed the 0x67DF1002 IDs in these both...

I (almost) found the solution to my own question: I noticed new AMD kexts in S/L/E: 9515, 9520 and 4200. In 10.12.5 9510 and 4100 were used. In 10.12.6 however this combination limits the clock at 300 MHz for whatever reason. I noticed that the GPU's ID 0x67DF1002 is used in 4 kexts: 9510, 4100...

Reporting with RX580 The good: Support out of the box without any kext modifications! Still need helper card though. Neutral (only for 5K displays): I have to inject framebuffer Guariba, 5K not working OOB The bad: Performance is a lot worse however. Luxmark is reporting about 3000 points...

It's a normal 4K monitor with one displayport cable... should be no problem.

We also have Displayport 1.4 in recent GPU cards, which supports up to 8K with only one cable. We just have to wait for DP 1.4 monitors. Normally monitor vendors are very fast with releasing cutting edge monitors, I wonder why they drop the ball on DP 1.4.

Really good for you, the mouse pointer bug was unbearable for me – I couldn't get rid of it. Whether I used hot corner sleep or screensaver or deactivated the shaking mouse feature, the mouse pointer bug occured in the next minute.

@nunziantimo 1. Dual boot is possible, but not quite exactly how you describe. You need a helper card defined as primary GPU in order to boot macOS, in my case it's the iGPU. It's hooked up via HDMI to my TV, since my mainboard doesn't have DP and the Dell only has DP inputs. So I can only see...
