I am glad to report that 10.8.4 update was quick and smooth.
Of course, I had to:
1) patch AppleIntelFramebufferCapri and AppleHDA;
2) replace AppleSmartBatteryManager.

@kpkp, have you ever tried to boot (and work) with Clover EFI?

No not yet, I am kind of waiting for it to be "more ready" and I do not see huge benefits yet, but yes there are some really interesting stuff, specially kext patching on the fly...

Do you mind sharing the new patched AppleHDA, I am a bit busy today and later I have to test if the "unified" capri script still works, thx?

Clover EFI bootloader works with 10.8.4, just have to reinstall AppleHDA, AppleSmartBatteryManager and AppleIntelSNBGraphicsFB after updating. Graphical glitches seem to disappear after update, but I need some days to confirm it.

I'm looking forward patched AppleHDA 10.8.4 too.

Clover EFI bootloader works with 10.8.4. just have to reinstall AppleHDA, AppleSmartBatteryManager and AppleIntelSNBGraphicsFB after updating.

Why AppleIntelSNBGraphicsFB? Ok, it's intel HD3k graphics.

Graphical glitches seem to disappear after update, but I need some days to confirm it.

Same here.

I'm looking forward patched AppleHDA 10.8.4 too.

Here's the patched AppleHDA.

The reason I am asking about Clover is that I use that for the last couple of weeks and I see sound assertions on boot with Clover (10.8.3 and 10.8.4) and no checkbox for Mic noise reduction. Other than that all works fine.
I cannot boot Chameleon right now, so can't verify if that's Clover problem only.

Booted Chameleon and still have sound assertion.

Sound assertion in AppleHDAEngine at line 17565

So, you're being warned, it's a kext (xml) problem.

I had the same issue (Mic), is not Clover related, I forgot to update the layout12.xml with the noise cancelation trick, I changed some other little things... Now it works for me, try it out and let me know.

 

[shpokas01]

I got somewhat mixed results.
Ambient noise reduction setting is back, but still have assertions at boot.

Sound assertion in AppleHDAPath at line 1360
Sound assertion in AppleHDAEngine at line 519

Anyway, all works

Same here.

It appears again, nothing improves. Graphical glitches only show while booting by Clover UEFI. Chimera and Chameleon works well.

 

[shpokas01]

Umm. with HD4k it's quite the opposite - no glitches with Clover EFI, but screen artefacts with Chameleon. Actually I am only talking about specific situation with docking station and booting with lid closed.

I investigated abit what is the "magic" behind the AppleHDA binary patch and it turns out it's really a simple little patch. So I decided to recreate the little script for it, makes it faster and safer, since it easier to mess up something when you use the more complex binary patcher. Anyways here is what the script does:

find 8B 19 D4 11 replace with 05 76 1D 11
find 84 19 D4 11 replace with 00 00 00 00

sudo perl -pi -e 's|\x8B\x19\xD4\x11|\x05\x76\x1D\x11|g' ~/Desktop/AppleHDA.kext/Contents/MacOS/AppleHDA
sudo perl -pi -e 's|\x84\x19\xD4\x11|\x00\x00\x00\x00|g' ~/Desktop/AppleHDA.kext/Contents/MacOS/AppleHDA

I did a bit of testing and in my experience only the first part of the patch is necessary, in other words I did not notice any side effects for not applying the second part of the patch in my limited testing.

I
find 8B 19 D4 11 replace with 05 76 1D 11
find 84 19 D4 11 replace with 00 00 00 00

Out of curiosity, do you any difference in system logs when patching 11d4198b vs. 11d41984 (sound assertions and ambient noise reduction)?
