Using a 49" Ultrawide on my Mackintosh

[rcurley55]

Hi All-

 

This is a great community. Using the amazing work on this thread below, I was able to get my EliteDesk 800 G5 running with Ventura.

 

 

The only issue is that I have a Dell u4919dw monitor, and I can't for the life of me get the integrated UHD630 to run the display at 5120 x 1440 (I'm stuck at 3840 x 1080). I have added the rx560 to the machine, and it recognizes that the card is there (see screenshot) but when I try to boot it using the tonymacx86 instructions to run the UHD630 headless and as a Mac19,1, the screen goes black midway through boot up.

 

If anyone has any suggestions on what to do, I would greatly appreciate it!

And don't mention tonymacx86 when you tell people not to mention tonymacx86.  LOL

 

EDIT: @rcurley55 I see that pastrychef hasn't visited for a while.  I hope he doesn't mind that I'm sharing what he sent me via PM:

I'm so sorry to mention the forum that should not be named!!! I didn't know.  Here are the headless UHD630 instructions that I followed on this board:

 

 

@deeveedee I had reached out to @pastrychef by PM but never heard back. Thank you for posting that information! I'll at least give that a try and am happy I can stick with MacMini8,1.

 

And @deeveedee Thank you SOOO much for all of your hard work on the EFI for the EliteDesk - I have learned so much from your tests and guidance!

@rcurley55 You are very welcome.  Glad to see that the thread helped you.  You'll find lots of great help from all the folks here at InsanelyMac.  I'm still learning from them.

So I have a partial success to report!

 

I disabled Whatevergreen, added my modified DMAR.aml, disabled IO mapper, and updated the settings in the bios. I wasn't able to figure out the PEGP -> GFX0 rename, BUT the card does boot and runs.

 

When I first set it up, it even picked up my 5120 x 1440 resolution!  On reboot; however, things get strange:

• the UI at the login screen gets huge and it defaults back to some tiny resolution once logged in.
• When logged in, I can set it to 3840 x 1080 @ 60 Hz through the Settings app
• With SwitchResX, I can get to 5120 x 1440 but only at 30 Hz.  
• If I move the monitor back to the PBP mode, let MacOS go to 2560 x 1440, then turn off PBP mode, MacOS will allow 5120 x 1440  @ 60 Hz in the Settings app

Very strange, but I guess I'm happy with that for now as a workaround.

 

If anyone can point me in the right direction for solving the rename and/or the changing resolution I would appreciate it.

So I was working to update this rig to Sequoia using the amazing work by @deeveedee over here: https://www.insanelymac.com/forum/topic/359277-hp-elitedesk-800-g4-g5-mini-with-rx560x-dgpu-hackintosh/

 

 

But I'm running into an issue and I can't quite figure this out. Here are the steps I took:

 

1. Pulled my old Apple WiFi/Bluetooth card

2. Disabled the m.2 slot for bluetooth in the bios

3. Downloaded the EFI from post 1 on the linked thread

4. Updated the Platform Info in the config.plist with the data from my current Hack (e.g., Serial, MLB, etc.)

5. Utilized the default USB 14-port kext

6. Created a bootable USB with the Sequoia installer (downloaded from the Apple App Store)

7. Removed my old SSD, put in a new one

8. Booted from the USB drive

 

It boots the first time to the installer, then reboots. From the menu, I chose to continue on the internal device.  It gets about half way through the install process and then just re-boots. It continues on that loop forever.

 

I have tried modifying the bios to boot to the iGPU, disable the iGPU, connect the display only to the iGPU and the dGPU - basically all manner of permutations between the bios settings and what display is connected and I can't get past this reboot issue.

 

Right now, I just have the Dell u4919dw connected directly to the RX560x via display port - no other monitors connected, but wouldn't mind the option down the road.

 

Any ideas? I have attached a zip of my EFI.  I would post on that thread, but I don't seem to have permissions yet.  Thanks for any advice you can provide!

@rcurley55 I started to diagnose your issue, but the number of differences in your config.plist makes it difficult for me to assess.  My recommendation would be to start again with the EFI that I posted and make minimal Platform-Info changes to the config.plist.

 

EDIT: Are you able to perform the edits without using OCAT?  The tool makes a lot of unnecessary changes that make "diff'ing" difficult.

Maybe that's the issue - the only thing I changed were the 4 values, but perhaps OCAT messed it up? I'll try to use ProperTree or something similar.

 

Thanks for the input!
