No Audio–Lenovo Ideapad 300-15isk

[Marshall2002]

I have successfully installed Mac OS High Sierra 10.13.4 on my laptop, but I am unable to work out some kinks in post install.

What Works:

Backlight Control

Lid Wake/Sleep

Keyboard

CD/DVD Drive

Ethernet

Bluetooth (though I can’t turn it on/off, its just stuck on)



What Doesn’t Work:

Audio (most important).

I followed this Guide, because it was the closest to my laptop he just has the i7 and I have the i3. I used his kexts and SSDT’s. I have tried booting with -f and rebuilding kextcache many times, but has not made a difference my audio still does not work. I can’t figure it out, any help would be appreciated.

Battery Status

I am using the latest ACPIBatteryManager.kext and appropriate DSDT but ever time I rebuild kext cache I get this error “ACPIBatteryManager.kext does not authenticate; omitting.”

Trackpad

I am using the latest VoodooPS2Controller.kext, but it still does not show up in system preferences. I read in the “Common problems with High Sierra” that it was fixable by installing the latest VoodooPS2Controller but its not working for me.

Wifi (this is not working because I have intel wifi, and can’t find any info on getting it to work)

Also every time I shutdown my computer the proper way via the menu when I start it up again it gives me the message that it shutdown do to a problem, even though it was shut down properly. Not a big deal, just a little annoying.



I will have my EFI below, as well as the output from rebuilding kextcache in terminal, and my L/E/ Folder.

"Problem Reporting" files are incomplete.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

All required Problem Reporting files should be below now.

Thank you so much for all the help

You're injecting layout-id 11 on HDEF. Are you certain that is the correct layout-id?

Note that your kexts are not installed correctly:

Kext rejected due to improper filesystem permissions: <OSKext 0x7f7ffb684920 [0x7fff8eeb6af0]> { URL = "ACPIBatteryManager.kext/ -- file:///Library/Extensions/", ID = "org.rehabman.driver.AppleSmartBatteryManager" }
ACPIBatteryManager.kext does not authenticate; omitting.

See FAQ for WiFi hardware recommendations:

You forgot to attach EFI/Clover (EFI not requested... it is too large).

You should check drivers64UEFI to see if you implemented NVRAM correctly. Read here for more info:
