Hello! I was able to install Mojave 10.14.2 on my E6430, but I have some problems with USB port. You can look at these pictures.
The first photo is on Windows 10,it has USB3.0 and 2.0 ,but USB2.0 is on 7 Series ,but 3.0 is not on 7 series.
the second picture is on mojava 10.14.2
I know that 10.14 limit numbers of usb ,but I don't think it caused it。If you have the same problem and you have sorted it. if You can reply to me,I will thank you very much。
