When people provide XML instead of a plist attachment, you have no choice but to use a text editor or a combo editor (such as PlistEdit Pro). At least with PlistEdit Pro, you will get an error if you do the paste to the wrong location.
Yes I understand that. What Ive been trying to say is that the OP has a large chunk of code for the plist, and I do not see how Im supposed to paste that using PlistPro. With Brackets I go to where I think its supposed to be pasted (see the imgur link I posted). With PlistPro I launch the app and then what? How do I paste code inside PListPro?
Anyway I followed the Clover guide to the letter. Created a USB installer for Sierra, edited the hd4400 plist version with the code supplied from the OP. I added all the kexts listed in the OP. Booted to Clover and did an F4 dump to get DSDT/SSDT. Went back to my Mac Mini and decompiled via IASL/Refs.txt etc.
I've never patched DSDT before but MacIASL was easy to work with. Following the OP I did each patch in order (probly not needed but easier for me to follow). I would do one patch, compile, check for errors then move on to the next. I did get errors when doing the remove WMI the first time, then half the errors doing it the second time, then no errors doing it a third time. Not sure if thats normal.
I *think* I did manual fixes correctly. I would add the code then compile and got no errors so I assume it went thru ok. Same with manual patches. Saved the DSDT in the format needed and placed in /patched on the USB. However Im confused about SSDT. Im still reading thru the DSDT/SSDT guide, but Im confused on SSDTs. I applied all the fixes/patches to DSDT, so Im confused as to what to do with the SSDTs. I opened some in Maciasl to see what they did, 1 had a bunch of references to backlight control so I do I apply backlight control patch/fix to that SSDT, then to get function keys working I need to find the SSDT that handles that and applies FN key fixes?
I did a test install with only the DDST patched and while I got to the desktop (with glitches during boot/login screen) it did work. Graphics seemed to be smooth but virtually nothing else worked. No FN keys, sleep/wake etc. So it seems Im not too far from a working hackintosh t440s. Seems DSDT/SSDT is where Im having a lot of issues mostly just from understanding the process (and before its mentioned, YES Im reading the FAQ.).
