macOS Sierra on dell vostro 3458

[adam_ar]

I used RehabMan's guide for laptops: https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/
Need help in fixing wifi and sound.

Current Status:
Graphics: Working. Full QE/CI and able to drive my external monitor Dell U2412M at full resolution.
Sound: Partially Working. No Stereo and sound crackles sometimes.
Battery Status: Working
Bluetooth: Working
Ethernet: Working
Wifi: Working
WebCam: Not Working
SDCard Reader: Not Working

The Full Story:

I was able to boot and install macOS Sierra successfully on this laptop. But it was without any of the much required functionality.
First off I tried to get intel HD4400 working using config.plist from https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/config_HD4000_1366x768.plist. This never gave me satisfactory graphics. I tried many things (device id, platform id, enable/disable intel gfx, enable/disable nvidia, fiddle in BIOS, etc.). Nothing worked to the point I gave up.
At this stage:
Graphics: jittery and just barely usable.
Wifi: No.
Sound: No.

Then I moved on to my wifi card. I had thought that I would get wifi suppport OOB after I replaced the default intel wifi card with a supported Dell DW1560 (BCM94352Z). Then I tried the FakePCIID_Broadcom_WiFi.kext along with FakePCIID.kext. Though many people reported working wifi with just this kext, I could not get it. Tried a few things without success. Then, I got a fix at http://www.insanelymac.com/forum/topic/312759-fix-macos-sierra-dp1-bcm94532z-wifi/. The solution was to find "81F952AA00007529" and replace it with "81F952AA00006690" in the AirPortBrcm4360 kext. This enabled my wifi card and I was able to use it.
At this stage:
Graphics: jittery and just barely usable.
Wifi: OK!
Sound: No.

Then I tried to find kext for my Realtek ALC3234 (ALC255). Couldnt find any. So used the VoodooHDA kext. got barely usable sound.
At this stage:
Graphics: jittery and just barely usable.
Wifi: OK!
Sound: Mono with crackle sometimes.

Then I thought of patching the DSDT and tried doing that and found the learning a little steep so abandoned it halfway.
And while I was figuring out stuff, I saw that I had missed reading RehabMan's post for Intel HD Graphics. I had been using the wrong config.plist all this while! I then used the correct config.plist and got full graphics support for Intel HD4400 Mobile graphics. Link to correct config.plist: https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/config_HD4600_4400_4200.plist.
At this stage:
Graphics: Fully Working.
Wifi: OK!
Sound: Mono with crackle sometimes.

At this stage I was mostly done. But I wanted to fix the sound crackle and stereo. All during this time, I had multiple copies of config.plist in my EFI partition. I was booting off the IntelHD4000 config plist renamed to config.plist and then choosing correct config (HD4600 and 4400 one) from Clover menu. And then I deleted my config.plist, copied over the HD4600 plist to config.plist. Now, all of a sudden my wifi was no longer available. I was getting "No Hardware Installed" in the status bar.
I knew, I had not added the find replace string to this plist so it was not working. So, I added the search/replace portion in the config.plist. Still no Wifi!. I rechecked that my kexts were present in EFI/CLOVER/kext/Other, I had search/replace portion in config.plist, that I am choosing correct config at boot time. But in-spite of all this, I could not find any way to re-enable my wifi card.

Tried acpi backlight kext but still cannot adjust my display backlight.
Finally I added ACPI Battery kext and Realtek RTL8111 kext for wired connection. Got it working.

Now that I think of it, I may have made more changes to the deleted config.plist and I am not able to recollect! Too many things I had tried.

One strange thing to note: when the OS boots up, I am able to use my trackpad without clicking (just touch works), but once I login, I have to click on the trackpad to click something. There is nothing in the preferences -> trackpad pane. After logging out on login screen, the touch does not work!

$ sudo touch /System/Library/Extensions && sudo kextcache -u /
KernelCache ID: 7592C9E634809D007D11AC42DB0B2D8D
symlink("/System/Library/PrelinkedKernels/prelinkedkernel", "/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache") failed 17 (File exists) <createPrelinkedKernel 2795>

The kernelcache symlink points to /Volumes/Image Volume/System/Library/PrelinkedKernels/prelinkedkernel. Earlier, I had removed this symlink and re-executed the kextcache command when I got the following output.

$ sudo touch /System/Library/Extensions && sudo kextcache -u /

EDIT 1
Trackpad preferences are visible after I started the PS2 daemon as per instructions at https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller/wiki/How-to-Install. I am able to click by touch after setting the preference. Pinch to zoom is still not working.

EDIT 2
Refer to post#3 https://www.tonymacx86.com/threads/macos-sierra-on-dell-vostro-3458.213871/#post-1429619.
I had put the search/replace patch in wrong section. putting it in the KernelAndKextPatches->KextsToPatch helped.

Thanks RehabMan! Will revisit the guides and attempt again.
I just logged in to report that my wifi is now working fine!
