I got sound working. Also, do you have color banding issue when using Launchpad or Dashboard?

 

After upgrading to Mojave and adjusting my clover config plist, I managed to get sound working somehow, before your post. Anyway, The only thing I have not working now is the bluetooth, I have installed the BCM94352Z Dell DW1560 card, WIFI works straight out of the box now, but I don't have any bluetooth. The bluetooth pane is not even shown in system preferences panes. I have spent an entire week trying to make the whole system work, so far almost perfect.

As for color banding issue... what's that? I don't have any issue using Launchpad.

Maybe it requires a new SSDT after I switched to a DW1560 wifi/bt card? Jesus, I have no idea how to do it if that's the case.

Here is the color banding issue I'm having: https://www.tonycrapx86.com/threads/color-banding-with-dell-g7.267005/

As you can see in the first screenshot, it looks like I'm on 16-bit color mode because of the weird rings but when I took a screenshot and opened it in Windows 10, it disappeared (2nd screenshot).

I haven't bought DW1560 yet so idk about it.

Ah, same on my Launchpad then. I didn’t think it was an issue but a limitation of intel gfx.

If you have a USB/Thunderbolt 3 to HDMI/DP, could you try plug it to another monitor and see if it have the same issue on external monitor? I think it's an issue with Dell laptop panel because when I use TeamViewer to monitor the hackintosh, it doesn't have color banding issue on Launchpad.

Same result here, with a 40” Samsung 4K TV, no color banding even though I don’t get a 4K image on it.

The Dell laptop display is a LED IPS, full hd display. However it shouldn’t happen.

So far, I haven’t found a way to make BT work.

[jbuttonfan]

I decided to leave BT for a while and focused on trying to get iMessage working. I generated the values required, and they do keep on boot, except for the board serial number. I cant make it stick. For some reason iMessage does not work.

I have a Macbook air, but I want to sell it after.

[ref]vinhtq115[/ref], I’ve found a few things that might help you with your issue:

I booted without any option set in my config.plist (iGFX, no inject Intel, no ig platform id) BUT using the Whatevergreen + Lilu kexts. System booted and the igpu was detected correctly as UHD 630 and correct RAM. But still got your color banding!

I then reverted back because sometimes I boot to a black screen.

To sum up, clover and WEG does have the info on UHD 630. Maybe it’s an issue with the framebuffer.

I am still trying to get BT, iMessage to work...

UPDATE: I’ve managed to get Bluetooth working. I just removed the SSDT-UIAC.aml out of my EFI folders (I saved a backup of it somewhere first). And rebooted. VOILA! My initial thoughts were right, it was the SSDT. I might need help to make a new one. Or I might not need it at all. I haven’t tested yet what else could have been affected by what I did.

I will now try to make iMessage/FaceTime work, and then I will be super happy if it does. But I am a bit worried with trying too much - I don’t want to get blacklisted by Apples servers. I will try a bit tomorrow.

Without ig-platform-id in config.plist, WEG will automatically inject it for you.

About the black screen issue, I think many people have it too. https://www.tonycrapx86.com/threads/bug-black-screen-3-minutes-after-booting-coffeelake-uhd-630.261131/

If you manage to fix color banding, please let me know. Although it doesn't bother me much but I still want to get it fixed.

[ref]vinhtq115[/ref], I keep getting an error message with the activation and to try again later.

I think it will not work until I find out why my iMessage Debug returns the Board Serial Number with XXXXXXXXXXXX instead of the value I generated in Clover. I have NVRAM working, any variable I set up to it still holds when I reboot so i know it works. For some reason, MLB/Board Serial Number is XXXXXXXXXXXX. I have even checked several times the Clover panels to find out if I had left something behind.

[jbuttonfan]

The system definitely needs a new SSDT-UIAC, when I removed it I had the bluetooth back, but I lost my USB ports functionality. How rude!

I need to learn a step by step on how to make a new one just so I don’t lose the Bluetooth.

Meanwhile I will keep a backup of that file for future problems.

Did you reboot after changing Serial and UUID?

[jbuttonfan]

Did you reboot after changing Serial and UUID?

 

Yes, I did. Generated new ones, saved config plist, rebooted, checked imessage debug, still no board serial number, even though I set MLB and ROM. I think one of them uses macAddr0.

I am now trying to create a new SSDT-UIAC for my system. Meanwhile, I noticed that the blue color of the selectors in macOS UI is a bit purple. Yours too?

Edit: fixed the SSDT. What happened is that who did it, might have had a typo (or the white G7 has a different port). Black model with the LCD display has the bluetooth on port HS07, instead of HS09. Changed it, rebooted normally and bang! USB ok, bluetooth ok, wifi ok. Camera ok. Sound ok. What is left for us now is the color issue on display and try to make iMessage/Facetime work. I still cannot figure out why the board serial number comes out hidden/unset in iMessage debug.

Go to Apple Menu -> About this Mac and see check if your SN is correct.

The SN is there, same as in Clover. What is not on iMessageDebug is the board serial number, used for MLB, even though I had set one for it in Clover.

I finally did it! I had to reset my network settings and preferences, then rebooted and tried to sign in... fuck yeah, worked!!

Now I have a 100% working system. Amazing.

[ref]vinhtq115[/ref], I also found a solution for your color banding problem. I haven’t tried yet, but I think you need to do framebuffer patching.

Can you share the customized SSDT-UIAC.aml?

I tried framebuffer patching but it didn't fix the issue. Maybe you could try?

[jbuttonfan]

I can share. But I am not convinced it is good - the USB speeds are making me scratch my head off a bit. I just edited the port number for bluetooth, the rest is left as it were before. I will upload it later, but you need to have the DW1560 card installed for it to work.

Framebuffer patches, I had no success in it. I don’t know yet how to do it properly. My first attempt left me with a darker display (reverted back later). For now the color banding isn’t a big issue for me, so I will leave it until someone makes an easier solution or explain in plain english how to do the framebuffer patching. I still think it has to do with the EDID. One of these two things are the cause of the problem.

Currently I am installing Xcode and later I will tidy up the Windows installation to run rFactor 2 - the reason I bought this model. Otherwise I’d have chosen an easier model to hack.

Sleep needs to be fixed as well. I left it on before xmas dinner and when I went back it didn’t turn on. Also, I had an usb 1tb storage plugged in, so when I rebooted, it refused to mount. Mounts well on my macbook air and also when I booted to windows, but not macOS. Turns out it was in exfat format, so i made a backup in other computer, formatted as NTFS and copied everything back. I can live with a NTFS usb drive, just need to have Tuxera NTFS installed where I may use it.

Here's the customised SSDT-UIAC. Requires black G7 model and DW1560/Broadcom BCM94352Z M.2 card to work.
