 I compiled a metallib and use Metal.framework(13.2.1-24),but timeout for WindowsServer🥶

It boot well in the whole process,but cause timeout and reboot at when about to enter the user interface of the system.....😖

Do you have any ideas? Attached is the list of metallib and patches I compiled.

ps:trying to fix Kepler on Tahoe

Spoiler

 

 

 

It's funny, I've seen these errors during shutdown/sleep where Bluetoothd and WindowServer are failing to terminate cleanly.

In my case the fix was USB mapping and Device Properties input for GPU.

And now I understand why I can't install Tahoe with you EFi @eSaF, it boots and then it gives me a black screen.

the last try results in the picture below ...

 

Did you update the new OC ?

To sum up, the USB ports are working, sleep is working, and there is sound via DP on the monitor. FileVault disabled it via recovery mode. As expected, WI-FI does not work)).  Thank you all so much for your help! You are the best!

If you want sound via external speakers we are using VoodooHDA which works surprisingly well.

Thanks to @Chris1111

Latest one... 2.4.2

 

https://dortania.github.io/builds/?product=RealtekRTL8111&viewall=true

 

Works OOB for me in OC kexts folder.

I tested the latest version on my system but for some reason the internet is very slow to load. Went back to my old trusted kext version and it is fine again, Go figure.

[LockDown]

stick with v2.4.2

For most sound cards, it is recommended to choose OCLP Mod and AppleALC to use the AppleHDA driver for better performance. Why choose VoodooHDA when SIP is lost in response?😅

The below is what ChatGPT says if its any help.

 

 

This issue typically means:

• WindowsServer fails to start (often due to broken GPU acceleration).

• You're dropped into launchd’s restart loop because the graphical interface cannot initialize.

---

🧠 Key Observations from the Screenshot:

• Messages like:

  makefile

  CopyEdit

  (Warning): Lingering coalition: 166 (com.apple.WindowServer)

  strongly indicate WindowServer crash or stall, confirming your suspicion.

---

🎯 Causes Specific to Kepler on Sequoia:

1. Kepler is officially unsupported in macOS Sequoia (macOS 15).

   • Apple removed support for non-Metal 3.x and older shaders.

   • Even with a patched metallib, you may also need binary patches to:

     • Skip Metal device checks.

     • Allow older GPU families.

     • Prevent system daemons from crashing on unsupported features.

2. Your metallib may not be compatible with the full Metal API expectations in Sequoia.

   • If shaders or Metal functions are missing or incorrect, WindowServer may crash or hang during rendering setup.

3. Missing GPUDevicePolicy patches — these are common when AppleGraphicsControl.kext prevents acceleration.

   • On older macOS versions we use agdpmod=pikera or similar boot-args.

   • You may need similar tricks (but patched for Sequoia).

---

✅ Suggestions:

1. Check GPU Acceleration Logs

Use -v debug=0x100 keepsyms=1 (you probably already are) and look earlier in the boot log:

• Do you see messages like:

  makefile

  CopyEdit

  IOAccelerator: Metal device not supported

  or

  lua

  CopyEdit

  GFX firmware load failed

  or

  makefile

  CopyEdit

  IOService: matching failed for AppleMGPUPowerControl

These will confirm failure to load GPU acceleration.

---

2. Try Headless Boot to Disable WindowServer

Try booting with:

bash

CopyEdit

nv_disable=1 -v debug=0x100 keepsyms=1

This disables Kepler acceleration to test if system boots without starting WindowServer.

If it boots: you have a working system minus graphics acceleration. That confirms it's purely GPU related.

---

3. Add/Check These Kernel Patches:

• IOAcceleratorFamily2 patch to allow unsupported GPUs.

• Patch AppleMGPUPowerControl or AGDC to skip model checks.

• Consider applying OCLP-like patch sets manually if using a Hackintosh.

---

4. Try Lilu + WhateverGreen (latest betas):

Even if they're not designed for Kepler on macOS 15, they:

• Inject missing framebuffer properties.

• Bypass some AppleGPU policies.

• Work better with patched metal libraries.

Also use boot-args:

diff

CopyEdit

-wegbeta -lilubetaall gfxrst=1 agdpmod=pikera

---

5. Use a Patched/Stub WindowServer (for debugging)

In some cases, you can replace /System/Library/CoreServices/WindowServer with a stub (like sleep 60) just to confirm booting — not usable for real work but helps confirm it's the cause.

---

🔗 Resources:

If you can share:

• Your metallib

• Any OpenCore patches/kexts you're applying

• IORegistry dump (from another machine)
  … I can help analyze what’s missing.

Speaking for me I am using VoodooHDA as a stop gap until OCLP is released with AppleALC and hopefully Wifi patched.  Your forked version is excellent but I have been using OCLP for a long time and my config.plist is set up for it. Just my 2 1/2 cents worth.

[STLVNUB]

Here Here My 5 Cents Worth

[macky1]

Sorry Pal but your post makes absolutely no sense.

The only difference between OCLP and this Forked version are:

1. OLCP-Mod is in the Chinese language so may make navigating the app difficult (but if you're a regular user of OCLP, you instinctively know where to click in the Mod version).

2. The other difference is it brings back the Audio lost in the release of Beta 2.

 

You are quite entitled to use the Mod version or not to use it.

What you are not entitled to do is to rubbish the effort of a Developer with negative remarks about their contribution that was gratefully received and used by countless members.

I wish I had a fraction of this young person's knowledge of development and software reverse engineering.

Read this Developers Bio and maybe you'll just about understand.

 

This is also my 2 cents.

Cheers.

How can I put it delicately I prefer to support OCLP. Each to their own I suppose. And I sincerely apologize if I affended anybody which was not my intention. The developer is excellent and I thank him for his contributions.

Did you update the new OC ? 

Yes it's OC 1.05.

[jsl]

After struggling for about 4 weeks at last my ASUS PRIME Z690-P D4 Hackintosh can boot Tahoe beta 2 with RX570 now !

No such issues of Finder, Firefox, LucyRTL8125Ethernet or Audio output.

The only problem waiting for fix is unable to wake-up from S3 sleep.

[Edit]

It seems FL1100 USB 3.0 adapter may interfere its power management of MB.

After removal of it and modified my config-new.plist it can wake-up from S3 sleep now !

[MorenoAv]

Good morning to all,

Tried your EFI @Anto65 that I'll appreciate, and it don't work, stops at "kextlog: Loading Pageable Kc from file /system7library/kernelcollections/basesystemkernelextension.kc.

tried to the EFI from @jsl, and it stops in the same line.

grrrrrrrr

[STLVNUB]

Ok, A Problem, rebooting from Tahoe to Sequoia Using Clover, I Loose My USB

Have To Use Laptop Keyboard To Select Sequoia

Any Ideas?

[MorenoAv]

@eSaF Following your suggestion changed from RX 570 to iGPU graphics in the bIos and disabled WhateverGreen, and it stops " In Memory Stackshot Succeed ** Bytes traced 65903 (uncompressed 164432)

[MorenoAv]

I only have active ALC, IntelMausi, Lilu, restrictedevents, usb map, and whatever green disabled in config.plis.

I think I can't boot if I disable one more

 

@Anto65 tried booting with your EFI and although I made the changes in the bios, it stops in the same place KC's

Edited June 29, 2025 by MorenoAv

[laobamac_yyds]

I use RX 570 Installed directly without any problems. Just disable WhateverGreen it can then be started and installed macOS Tahoe. If the startup process is in the PCI or AppleKeyStore stop at, try adding-amd_no_dgpu_accel add to startup parameters.

 

 

 

WhateverGreen will only cause a startup failure during installation, when you start "Macintosh HD" (your installation target name, after the installation process is complete), you need to enable it for your RX570 to work properly.

 

 

 

Ps: you said that your EFI stopped and crashed at EB, which was not caused by GPU at all cause, you should check something else, like the OC version, kext Version...

would try only with integrated and WEG enabled... try again with my EFI (if you want)

Yep I keep tryin 👌

[MorenoAv]

One more try with your EFI @Anto65, and it hangs in the same place the already famous for the wrong reasons, KC's
