@Sniki and
@RehabMan;
wanted to say thanks for all the efforts on this front. Just finished installing macOS Mojave 10.14.2 on a T440s with the following specs in case that helps anyone else:
Lenovo T440s
i7-4600U, 2.1 GHz
1600x900 resolution display
4Gb base memory
256 SSD
This machine came with a standard T440s touchpad in place whilst installing, which worked horribly (and I am not just talking about the mechanics of it), so I just replaced it with a T450s touchpad, which works beautifully at the moment.
Other than that, all I changed was the config.plist file's #Screenresolution setting in accordance with above specs.
Installation took a long time, but sticking to the combined instructions (see links etc. in the October 6th 2018 (#128) posting) seems to have paid off. Wifi/Bluetooth is non-functional at the moment, but that is because the original wifi card is still in there, I was too lazy to go through the BIOS mod procedure/wifi card purchase. Everything else tested so far works, including VGA port connectivity.
