I have it working on the Mac and also a windows installation in a VM.
They have to be clean installations though, I have had some errors when adding the Ender 6 files after I had already run Cura before doing the changes. Deleting the user-data in the ~/Library/Application Support/cura worked for me.
I used the Ender6 files from the Creality slicer. I had to change the version of these files, and also change a few files to make the profiles work with the materials again. (There has been a default name-change along the way which broke things: 0.4mm to 0.4mm Nozzle)
It appears to work although because of a broken fan I have not printed anything.
A file with the files to add can be found here:
Do a clean install of Ultimaker Cura and/or make sure to remove all user settings
- MAC: remove ~/Library/Application Support/Cura
DO NOT RUN Ultimaker Cura yet!!!
Copy provided files to their respective folders in the resources folder of your installation
- MAC: /Applications/Ultimaker Cura.app/Contents/Resources/resources/
- WIN: C:\Program Files\Ultimaker Cura 4.8.0\resources
Overwrite when prompted
Start Ultimaker Cura - you should be able to choose the Ender 6 printer now.
