I wonder if there is any chance of Mojave running on this model laptop?

https://osxlatitude.com/index.php?/topic/5966-details-about-the-smart-touchpad-driver-features/ has some interesting values for various settings. Some of them align (more or less) with items in the Cypress panel. I've also been looking around to see if there's any possibility of swapping the Cypress touchpad for a Synaptics or Alps that is more compatible with MacOS. Can't seem to find anything that definitively says this one or that one will fit the XPS 13 L321X, though.

Anything in this post helpful for us to figure out how to tweak this Cypress touchpad into actually being useable? http://forum.notebookreview.com/threads/voila-hacked-dell-drivers-for-u300s-cypress-trackpad.665303/

Thanks Jake. I'll give that a try. PS: Sleep seems to work OK for me when Sleep-ing from the menu it wakes up when I open the lid. I notice that it does take a good minute or two to get to sleep after the menu is chosen. Suppose that's normal/expected.

I'm curious, do either of you have the brightness controls working (Fn+F4 and Fn+F5)? It's not a big deal for me, but would be nice to have. Thanks!

I'm using DW1510 Broadcom BCM94322HM8L in mine. Have to confess I've not even tested Sleep yet. Perhaps I should do that soon

You've all been very helpful, patient and kind. Please accept my sincere thanks for your assistance.

Followed your directions again tonight Jake but had no luck...just kept getting same results I've been getting. Decided to Google around to see if I could find a fresh copy of the ALC275 kext to download...thinking maybe the copy I have is corrupted. In my searches, I came across https://github.com/insanelydeepak/Patched-AppleHDA-for-Mac-OS-Sierra-10.12 which led me to download the kext for Audio ID 28 from here https://bitbucket.org/insanelydeepak/hdaenablers-applehda-for-hackintosh/downloads/ Upon installing the kext, look what happened

Yes...I restarted Also tried using Kext Wizard Same results

I also keep getting this alert Updating perms & cache doesn't seem to make it go away.

Uninstalled VoodooHDA Replace my DSDT with Jake's DSDT Copied AppleHDA_ALC275.kext to S/L/E Fixed perms and rebuilt cache with the following results locals-MBP:~ localuser$ sudo chmod -Rf 755 /L*/E* locals-MBP:~ localuser$ sudo chown -Rf 0:0 /L*/E* locals-MBP:~ localuser$ sudo touch -f /L*/E* locals-MBP:~ localuser$ sudo touch -f /L*/E* locals-MBP:~ localuser$ sudo touch -f /L*/E* locals-MBP:~ localuser$ sudo chmod -Rf 755 /S*/L*/E* locals-MBP:~ localuser$ sudo chown -Rf 0:0 /S*/L*/E* locals-MBP:~ localuser$ sudo touch -f /S*/L*/E* locals-MBP:~ localuser$ sudo kextcache -Boot -U / rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext EAPDFix.kext KernelCache ID: 49C8B53C168CEA1F2AC096D9697E5C48 File at path '/System/Library/PrelinkedKernels/prelinkedkernel' changed, cannot be used Child process /usr/sbin/kextcache[689] exited with status 77.

Aren't you using the i5 version of the L321x? I have the i7 version. I didn't think I could use your DSDT (or SSDT) files if we have different hardware/CPU configs.

Perhaps I need to redo my DSDT from scratch and retry the 275 audio kext. Which patches do you recommend?

Thanks guys. I punted to VoodooHDA last night. Audio seems to work well so far with it. I'm keen to try the Cypress touchpad kext. One question though, how do I install the prefpane? Not sure I've ever encountered one of those before.

No luck with AppleHDA275.kext

Still no audio Am I missing something in my config.plist perhaps? Jake, I'm using the one you provided as a bootpack earlier in the thread. I only edited in my own SMBIOS details. config.plist.zip

My apologies for the spoon-feeding guys. I am grateful for your time and your help.

In S/L/E Wrong Place?

I don't seem to have either of those in S/L/E

Yes, I believe I have the HDA275 kext installed properly. Check screenshot below. Is that the right one? I believe you have the i5 version of this laptop, while I have the i7 version. I don't think we can use the same SSDT (or DSDT, for that matter). But to your point, I've ran the SSDTPRgen.sh script from Piker and created my own SSDT and installed into the CLOVER\ACPI\patched folder. Sadly, it did not resolve my audio issue.

Hi Jake I've installed your KEXTS and am using your config.plist file now. I've got battery working, but still no audio devices. My system is the i7 model, but I think that shouldn't make a difference for the audio to work. I've included my EFI folder. Perhaps something in there might help diagnose my error. GatorGeek_EFI.zip Thanks again for your kind help.

I've made some progress from earlier today using the Ubuntu method to convert my disk from GPT to MBR. I've got some tweaking to do to get Audio working, Battery percentage and some other things, but at least I'm moving forward again. I sincerely appreciate appreciate all the suggestions and assistance.
