Edit: 
 
New Guide Section E.11) - ASUS Boot Splash Screen Cosmetics
 
Based on the ideas and instructions of @Matthew82, I achieved an iMacPro ASUS BIOS Boot Splash Screen implementation, which hopefully will further motivate you in patching your ASUS BIOS Firmware.
 
New Section E.11) contains all necessary details.
 
Note that the new iMac Pro Splash Screen Image is already part of the patched 1102 ASUS Prime X299 Deluxe Firmware X299D.CAP, newly implemented in the guide in the originating post of this thread. I once more attach this patched BIOS also here below. 
 
Please note that for the new iMacPro ASUS Boot Splash Screen patch approach, it is mandatory to set BIOS setting "Boot Logo Display" to "AUTO"
 
Enjoy and have fun!

Hi KGP

is there ESP/EFI/APPLE/UPDATERS/MULTIUPDATER/flasher_base.smc?

if there is, please upload file.

 

Not that I would now, sorry @Sherlocks.. 

 

------------------------------------------------

 

New Section E.12) - Native Display Brightness Control / Native NightShift Functionality for Monitors with DCC/IC Support

 

1.) Native Display Brightness Control 

 
Many of you might miss the ability to control the display brightness with the F1/F2 keys on original Apple Keyboards, or with FN&F1/FN&F2 on non-Apple keyboards. 
 
@bensge wrote a small but genius application to do just that on any Hackintosh System and to show the native OSX brightness system UI.

2.) Native NightShift Functionality for Monitors with DDC/IC Support
 
post-1362934-0-75327300-1517066510_thumb.png

 

Native NightShift works so far for the 38" LG 38UC99. NightShift should also work for the Acer 38" and Dell 38" Monitors. Yet @Ramalama misses the respective EDIDs. Any body with e.g. the Acer XR382CQK should immediately upload the requested information and contact @Ramalama by respective postings! Many thanks in advance!
 
Many thanks to user @Ramalama for providing both Native Display Brightness Control and Native NightShift Functionality for Monitors with DDC/IC Support also to our community and this thread. 
 
For further details and instructions see new Section E.12) of the guide in the originating post of this thread. 
 
@Ramalama, please let me know if yet we miss any reference concerning the Native NightShift implementation. In my opinion, the references for the Native Display Brightness Control implementation should be complete and fully covered.  
 
Enjoy and have fun

Good news about 10.13.4 benefits.

1. Sleep working native. No need ssdt or any patch.

2. After many years apple fix radeon initialization and wake function. No more need RadeonDelnit in Cover or ssdt inject. 

3. GPU Famili1 v3 for metal in RX GPU 

 

One sed thing - Port limits patch is not working anymore

attachicon.gifZrzut ekranu 2018-01-25 o 15.53.13.png

 

First time my acpi patch folder look like it should  :) attachicon.gifZrzut ekranu 2018-01-25 o 16.04.24.png

 

It is easy to show an empty /ACPI/pacthed/ folder .. I can do that too... I just have to delete all files :rolleyes:

 

But did you look to Section "PCI" in Apple's system report and compare it with mine? :wink_anim:

 

In my opinion, there is simply some need for ACPI DSDT Replacement Patches (HDEF is the most trivial example) to make the Hackintosh world compatible with the real Mac Environment.

 

Also an SSDT.aml has it's function and justification ....

 

If you think that you better live without it, good luck ;)

 

BTW.. Sleep/Wake still does not work natively, also not under 10.13.4 Beta 1.. Error E3 remains.. still need the idle Kernel patch to wake from sleep and live with all negative consequences...

New patch for usb limit in 10.13.4

 

  • AppleUSBXHCI - 837d940f 0f839704 0000 > 837d941e 90909090 9090

 

 

Thanks Matthew! But can we clarify one thing? Following @PMHeart, the port limit patch should be obsolete on Skylake-X/X299 systems under 10.13.4 Beta 1. I was able to confirm this guess on my system. Do you really need the port limit patch under 10.13.4 Beta 1 on your Skylake-X/X299 system?

 

Appreciate your feedback..

It was within some PM... I guess it is fine with @PMHeart if I make the corresponding part of the PM public... (see figure below)..

Without patch I have only 10 part working. 

With patch working all. So thing KGP have Asus deluxe special edition :)

Don't forget.. I use so far my XHC Kext and XHCI instead of XHC1..

Thank You KGP

But now I am more confused

In that post you talk about 10.13.3 and also previously beta

But I thought port limits were removed only in first 10.13.4 beta 1? Or not?

 

I can't follow very well all passages of your extensive and great guide 

I would like to understand better:)

BTW.. I just realised once more that my XHC kext does anyway not use more than 10 HS ports and 4 SS ports. 
 
This might be also the explanation why I do not need the XHC port limit patch.. 
 
I cannot try to skip the port limit patch without my kext because apparently the kext is required during betas, as OSX injects without my kext the wrong AppleUSBXHCISPT driver for my Asus Prime X299 Deluxe onboard XHC controller. In all final releases, the correct driver is injected and I do not need the kext..  

 

Cheers,

 

KGP

Thank you KGP

But this image seems to give some evidence to Mathhew82 and to me :)

 

I would like to suggest you a thing with no polemics at all (you do a great job in your guide.. maybe to extensive for me however great job)

try in that condition to put port limits you can find in Matthew82 thread and repost your similar image

I don't know well if also a rename to XHC is needed to have a working port limit patch

PS

I think also like happen on my actual X99 system to have all ports working well also x299 system need of a rename and a proper bios setting

But I can't test directly for now

Thank you for your time

attachicon.gifZrzut ekranu 2018-01-29 o 16.38.14.pngThis is with patch. 5 more ports. 

 

Because you use XHC1  ;) ..With XHCI, the port implementation looks different...

 

I was creating my kext within the USB Emergency Configuration.. No need for HS 1and 2 and SS 1 and 2 with XHCI

 

Anyway, I guess it is not wrong if you claim that the XHC USB port limit patch is still needed but it might depend on the XHC implementation..  I cannot confirm the latter with my Asus Prime X299 Deluxe in macOS betas... I have to use my kext, which enables all XHC USB ports without the need of any port limit patch.

 

Do you understand what I mean?  

 

In any case, if the port limit patch is still needed with some XHC configurations under 10.13.4, @PMHearts initial guess seems not to be confirmed by your observations. Which is totally fine with me..
