    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    @ShortFormErnie I wanted to say thanks again for being patient with me. Made a few noob mistakes but I have a better handle on the process because of it. I'm considering getting the Broadcom card and getting bluetooth and wifi working. As of now, I use a dock and get internet connectivity that...

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    OK so I had redone all of my DSDT/SSDT patching because I had tried a few patches to get things working and wanted clean versions with only the patches I was actually using. In doing so I did not apply the patch in the OP of this thread. Actually my first time through that section of the OP I...

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    I installed ACPIDebug.kext to L/E Applied "Add DSDT Debug Methods" and "Instrument EC Queries" to my DSDT.dsl Saved it as DSDT.aml and replaced the one I had in the Patched folder with it. I rebooted and pressed the keys while viewing system.log in Console but saw no entries. An odd thing I did...

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    OK so I have the backlight working via the slider in System Preferences/Display. I can't seem to get the buttons mapped. I followed this guide https://www.tonymacx86.com/threads/guide-patching-dsdt-ssdt-for-laptop-backlight-control.152659/ but am not getting results in Console for either PS2 or...

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    Happy to report I figured it out. I was using the latest AppleALC (1.3.0) which just doesn't seem to work. Downgraded to 1.2.8 and sound is working.

    I was planning on moving it after testing because I read that EFI/CLOVER/kexts/Other is guranteed to load before AppleHDA does. I'll move it and try again.

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    I added AppleALC.kext to EFI/CLOVER/kexts/Other and tried setting inject to 3,13,28, and a couple others but nothing. There is no sound device in System Properties/Sound.

    Thank you for the clarification. Unfortunately, the OP has it differently. Hopefully the user will edit it at some point.

    Thank you for the quick reply and words of encouragement. I'll give AppleALC a go. You just gave me an idea though. I ordered a dock that has audio the other day. I plan to use this mostly when docked. Perhaps the external audio will work better.

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    Ok so I am embarrassed to say the following code in my plist was , in fact, not disabled: <key>Comment</key> <string>0x19160000/etc, 32MB BIOS, 19MB framebuffer 9MB cursor bytes (credit RehabMan)</string>) <key>Enabled</key> Beyond the fact my hex was different I was also viewing it in the...

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    Thanks to you I am able to get back into the system. For me, that setting was already checked. I unchecked it and was able to boot although the display had lines at boot and I was seeing artifacts while using terminal. So as you said this is suitable for testing. A few followup questions...

    UPDATE: I patched my DSDT and here is the appropriate screenshot/EFI package. Looks like I cleaned up the ACPI errors but still halts on a similar section.

    [Guide] High Sierra on HP Spectre x360 8th Gen Coffee Lake

    Hello All, Let me preface with I have never attempted something like this before but I have read the guides here multiple times before beginning the process. I have created the Clover USB installer, installed High Sierra on an external SSD (I would prefer this type of setup, however, if it...
