The following layers were not correctly generated.

I installed SAGA GIS 9.4.0 in the Applications folder and tested the installation. It works well.

After this I installed the "Processing Saga NextGen Provider" and defined the SAGA folder as "/Applications/SAGA.app/Contents/MacOS". After restarting QGIS and testing the 'K-means clustering for grids' I get the following error message
