I was able to get Mojave working. 

Intel Wifi card doesn't work, so waiting for a Wifi USB dongle to arrive. Most everything else seems fine. Battery life seems good.

Worst problem is the trackpad control is quite funky. If you move your finger fast over the trackpad (i.e. want to quickly get from one side of the screen to the other), the pointer becomes very jittery and doesn't move much. Can be helped somewhat with a pointer speedup in the terminal (defaults write -g com.apple.trackpad.scaling X (where 'X' is a value, probably around 10...do a restart to test)), and an app called Mos that helps two fingered scrolling .

If anyone was able to fix the pointer control, please let us know. It's quite frustrating.

Thanks Hervé,

That's very useful to know.

Hi again,

Did you need to use the Mojave Patcher tool to install Mojave on the X1 Carbon 3rd Gen?...if so, what machine type did you select?

Hi,

I'm about to give this a go...

Just curious what guide you used?

Also any pitfalls I should be careful of, and where you able to fix your issues (Sound, Battery etc)?

Phil
