  1. I have that kind of behavior of HDMI sound: If my laptop is powered off and switch it on with HDMI plugged, I got no sound in booted OSX. To get sound working I have to replug HDMI or switch off/switch on my monitor. After that sound appears. Is that normal or it can be fixed?

     

    The thing that bothers me most is that magical DVMT value revert... In your post it's said that the setting is preserved even after BIOS update. I'm afraid that this could happen during business trip so I'll have to bring usb flash with uefi shell to be able to set it back :(

  2. I fixed screen flickering. Just replaced IntelBacklight.kext with a new one. 

    Also I added EmuVariableUefi-64.efi driver to preserve brightness, volume level after reboots

     

    One thing that bothers me then happened. After several restarts I had kernel panic at assertion in AppleIntelFramebuffer.kext. That was due to DVMT value magically reverted back to 0x1 and I had to set it to 0x3 again. After that I cannot see Nvidia chip in System report now, so I think it's disabled now.

     

    I looked for my wireless card and discovered that it's not 1/2 miniPCIe but NGFF. I suppose Dell DW1560 (Broadcom BCM94352Z) is the only card that would work in my case?

     

    I updated my first post.

  3. Jake Lo, can you help me with disabling nvidia please?

    I have a problem with sleep when plugged to AC adapter. After I press sleep button it instantly wake up. I see "kernel: Wake reason: GLAN" in console. This problem occurs only when plugged to AC.

  4. After adding FakePCIID_XHCIMux.kext & FakePCIID.kext files camera started working!!! My card reader also appeared in usb devices list but it's not working (I suppose it won't work at all) Currently I see Nvidia chip in system report with v3 and v4 dsdt attachments.

    I've made some investigation regarding hdmi sound. I can't hear any sound if I boot laptop with HDMI connected. However, when I reconnect HDMI the sound works OK. Here are two IOreg files with working and not working sound.

    Almost all is working! Thanks! Is there any chances to make hdmi sound working without reconnecting it after startup?

    Is there any chances to fix this screen flickering during boot process? Screen flickers only when booting from battery and it stops when [igpu] entries saying that graphics acceleration enabled appear on console.

  5. No, I didn't touch Nvidia in BIOS. You disabled it in DSDT as far as I remember. But in your later DSDT attachment (ver.4) it is enabled. I see it in System report and I heard sound through HDMI. However it disappeared after restart. You mean saving IOReg next time I hear sound through HDMI?

  6. I'll try updating clover.

     

    I don't know exactly if it's an UVC. I can find my VID 064E here http://www.ideasonboard.org/uvc/#devices but not my PID 920B. I can't see any info about manufacturer or model but it works perfectly without any drivers in windows and ubuntu linux, so I suppose some standard drivers suit my camera.

     

    I tested HDMI and it's working, however I have no sound through it (I have monitor with speakers). Is there any chance to make them work?

  7. Thank you for your reply I appreciate your help!

     

    Brightness - yes, that's good but is there a chance to avoid that screen blinking during start up?

    Sound - I've put these two kexts and repaired permissions according to your guide

    Camera - according to device manager in windows its VID is 064E and PID is 920B. This camera works without any additional drivers in windows 8.1 and ubuntu 14.04

    SD Card reader - yes it's Realtek with VID: 0BDA and PID: 0129

  8. I have duplicate entries in Clover now as seen on photo and screen blinking during start up as seen on the video

    However, system starts.

    Brightness with F11-F12 button - WORKS!

    Sleep - WORKS but after wake up the screen is unlocked and I see messages that my USB flash drive was not unmounted properly.

     

    Sound - not working

    Camera - not working

    SD Card reader - not working
