About the HD4000 patches, do they enable the HDMI audio? Because the HDMI port works even with vanilla AppleIntelFramebufferCapri.kext, only the HDMI audio is missing.

I'm not sure about 1366x768 patch, but based on toleda's post, changing to 8000006000000 will enable HDMI audio.

Ill try this and report back later on after work (using display port)

just to be clear.. is this for any laptop with the above mentioned HD graphics, or just HP models?

 

[nguyenmac]

Any laptop. The HD4000 patch is based on the ig-platform-id you used

I assumed 1366x768 = 0x01660003, 1600x900+ = 0x01660004.

Btw, if you're using 0x01660003, DP and HDMI ports are enabled by default, the patch is for audio HDMI only.

If your 8470p has a low-res screen you do not need any patches, if it high-res, then you try the "Patch HDMI-DP port HD4000 1600x900".

@philip_petev
That patch changes the connector type to HDMI, so it should be ok.

@nguyenmac
It is interesting that if you split the big "HDMI-DP port HD4000 1600x900" patch in 2 parts it works... Maybe there is a size limit after all or what have you discovered regarding this?

I'm not sure if there is a limit, I tried two super-long Trim Enabler patches and they still work, but the long CapriFB patch you mentioned before does not work.

Also, The part between my 2 new patches are altered in 10.9.2, so I think this is better (until the patch does not work anymore).

My friend has tested 1600x900 patch and it works, I haven't tried myself though. Did you test the patch?

 

[rob1980]

Well, Ive put back vanilla kext, both HDMI and audio are working..

Can anyone upload vanilla AppleIntelFramebufferCapri.kext in case mines not vanilla (pretty sure it is, its from install USB)

Here you are, 10.9.2 version. To check if your current is vanilla or not, open System Information > Extensions, find your kexts and check if "Obtained from" is "Apple" or sth else.

Ah strange... But yeah this solution is even better for Clover, since you can have different patches for different resolutions... My patch was to make one universal kext, but that is not relevant for Clover.

Also, The part between my 2 new patches are altered in 10.9.2, so I think this is better (until the patch does not work anymore).

Thx for the heads up, I knew there was a change from 10.8.5 -> 10.9, but didn't know about the 10.9.1 -> 10.9.2. I will check later, because I am a bit curious what Apple changed.

My friend has tested 1600x900 patch and it works, I haven't tried myself though. Did you test the patch?

I am not using Clover at this time yet, but yeah on the fly patching is slowly convincing me to jump ship.... I am quite sure it should work, based on the patch alone as long as Clover "swallows" it.
