Comment 7 for bug 1490762

Further testing on this issue let me to believe that there is still some data in the system which results in that error message. I was able to remove it by doing the following: removing completely homebrew (/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" -> may suggest to remove some other dirs in the end, also did that) and/or macports(https://guide.macports.org/chunked/installing.macports.uninstalling.html) and removing kicad completely. (kicad Application and kicad Application support folders).

Unfortunately, I did this in a single step and I am not able to be more precise on the step that really solved the issue. Now there is no error message.

I have some doubts thought on a correct behaviour of the application... When I open the footprint editor (without a pcbnew window being opened first) I get a blank pcbnew window and the footprint editor. But, nickoe confirmed this same behaviour on a windows machine... so it should be all fine with this work around.

Not sure if this ^^^^^ can be addressed like a bug... I have attached a screenshot...

If anyone could first try to remove completely remove kicad folders and preferences, to test this solution and post the results would be much appreciated...
