I got my hands on a Dell Latitude 3450 and I'm trying to get everything working...
Specs:
BIOS: A13
CPU: i3-5005u
GPU: HD 5500
Audio: Realtek ALC3234 (aka ALC255)
Wifi: Qualcomm/Atheros AR9565
Ethernet: Realtek RTL8111
Storage: SATA 3 SSD​
SMBIOS: MacBookAir7,1
Clover: 3998
macOS: 10.12.3
What is working:
Keyboard (via RehabMan's VoodooPS2Controller.kext v1.8.25)
Trackpad (via RehabMan's VoodooPS2Controller.kext v.1.8.25) but 3 finger gestures not working correctly
CPU power management
Sleep/Wake (but does not sleep when lid closes)
HD 5500 QE/CI acceleration (via Clover patch)
HDMI
Ethernet (via RTL8111 kext)
Wifi (via drivers found on internet)
USB 3
Battery indicator
AirPlay Mirroring (but no audio)​
What's not working:
Audio
Sleep when lid closes
Screen Brightness Control
HDMI Audio
USB 2 port
Bluetooth​
I read through lots of information but when it came time to compile my DSDT, I encountered syntax errors that I simply didn't know how to overcome... I currently already have the ALC255 and Codec Commander in my /Library/Extensions/ folder. I've attached my DSDT/SSDT files from Clover F4 extraction (also in Clover folder), IORegistryExplorer file, and my Clover folder for review. Any help would be greatly appreciated. Thanks in advance!!
