I recently install macOS Mojave 10.14.3 on my Dell Latitude E5550.
Everything is working, I followed the guide and the post install.
The only thing that bugs me is that the media buttons don't do anything.
Is there anyway to enable them at all?
I also left a picture of the keyboard. I highlighted the keys just in case of confusion.
I'll need new debug file.
But before you do, let's remove some unnecessary kexts
Replace DSDT and Config with the attached
Not sure which Config you use to boot, but change Inject layout-id from 3 to 12
Add the 2 aml files to the Patched folder and kext to the Clover kext folder
Should get you battery status, brightness control and maybe audio too
