    [Catalina] Dell 4021QW DP black screen issue

    @Middleman Thanks for the fast and thorough reply! Really appreciate it. :) Tried to follow your explanation but it went a bit over my head. It pushed me in the right direction though. I use a SSDT for the Vega56 (SSDT-X299-Vega56.aml). After I removed that one everything started working...

    [Catalina] Dell 4021QW DP black screen issue

    That workaround unfortunately doesn't work for me. Even with pulling the power plug on the monitor. The problem is the DP itself. It has to be changed from Port 1 to Port 2 on the graphics card (or vice versa at the next boot). Plugging it in at the same port again doesn't work.

    [Catalina] Dell 4021QW DP black screen issue

    Hi, Running Catalina 10.15.7 here and ran into a strange issue. Just got my new Dell 4021QW, everything boots and works until after I login. After the login the screen goes dark and the display detects no DP signal. No comes the strange part, when I move the DP cable to the other DP port on the...

    So what's the point then to suggest it for a hackintosh build?

    iMac Pro X299 - Live the Future now with macOS 10.14 Mojave [Successful Build/Extended Guide]

    Yes, but does that card get recognized as Airport Xtreme right out of the box? As for the other four. They are all broken links or out of stock.

    iMac Pro X299 - Live the Future now with macOS 10.14 Mojave [Successful Build/Extended Guide]

    Hi, I just wanted to give a hardware recommendation. I found a much cheaper version for Wifi/Bluetooth: https://www.amazon.com/gp/product/B07FYGY54D/?tag=tonymacx86com-20 Half the price of the other card. Took two weeks to arrive and worked out of the box. Seems to have a very decent build...

    iMac Pro X299 - Live the Future now with macOS 10.14 Mojave [Successful Build/Extended Guide]

    Hi @kgp ! First, thank you for the fantastic guide and all the help you provide. This build wouldn't be possible without you. I followed all your instructions and everything works, except for some issues. (same board and graphics card as you) - I can't get the audio to work, tried AppleALC and...

    [Solved] Dual setup - 2nd screen landscape doesn't work properly (RX570 - U3818dw & U3417dw)

    Just figured it out. You have to select "Show mirroring options in the menu bar when available" in the System Preferences and then select "Use as seperate displays" from the menu bar icon.

    [Solved] Dual setup - 2nd screen landscape doesn't work properly (RX570 - U3818dw & U3417dw)

    Hi, I just got a Dell U3818dw screen in addition to my U3417dw one and ran into a funny problem. Both screens get detected and work, but when I rotate the 2nd screen to portrait in the settings, the first one gets smaller and mirrored to the second. I have an ATI RX 570. The card def. can run...

    Thanks! That did the trick. Looking good again. Totally weird.

    macOS 10.13.6 Update

    Installed without a problem with the combo update. Now I have the "rainbow color" effect on type like others already reported. Is there a fix for that?

    TP-Link WDN4800 does not work on upgraded High Sierra

    I got it working. I have a dual cpu system with two PCI buses. I switched the card to another slot and it started working right away (10.13.5).

    Poor performance with NVMe and High Sierra

    Cloned the drive, formatted it as APFS and cloned it back. No more strange delays during booting and the performance is back. <phew> (1800 read/write)

    Poor performance with NVMe and High Sierra

    I converted the drive to APFS. Now the write speed is down to 200MB/s. This is ridiculous. I have no idea how to fix this.

    Poor performance with NVMe and High Sierra

    No, I avoided that since many people reported to stay away from APFS on a hackintosh for now. The performance was fine on HFS+J on Sierra (1700 write/read).

    Anyone got a Dual Xeon working on High Sierra?

    where can I see this? I checked the /var/log/system.log but couldn't find any hint there. attached. Thank you!! :) Nice! I got around this by booting EFI from a hdd. What model do you have? What are your transfer speeds in 10.13? There is something wrong with my write speed. I got 1700kb/s on...

    Anyone got a Dual Xeon working on High Sierra?

    this ssdt-1.aml loads fine this ssdt.aml isn't required, it's a leftover from testing ok, unchecked How do you use that? If I click +, it only gives me an entry for GFX0. Unfortunately that's not true in my case. If I removed those patches and just check AppleIntelCPUPowerManagement I get a...

    Poor performance with NVMe and High Sierra

    I have the same issue with Samsung 960pro and High Sierra. Max 800mb/s write, but it drops usually to around 600mb/s. On sierra the same drive was around 1700mb/s for write. You can see in the graph that there are peaks that are high speed, but only very short. Samsung 960pro Speedtest by...
