I was able to update my Mojave installation done with this Tools and Guide on my t440s to catalina 10.15.0 and to 10.15.2 without any major issues.
Sound does not work yet but I will fix it soon. It´s working great.
Again great work
Great Work. I have tested it on my t440s and it works perfekt. I used Kext Wizzard to copy the required kext into the correct folder. Even after update to the latest mojave version it works great.
I will see if I can install Catalina on this 440s , maybe someone can give me a hint...
