I’m a long time users of Google Sketchup for Mac. I’m running OS X 10.10.2
After downloading and setting up Sketchup 2015, I tried to use the fill tool and select a material in the window. The first time I did so, it allowed me to choose the material (a wood grain), but wouldn’t fill the selected object. I tried to go back and could no longer select ANY material. The fill tool works fine when I select a color. I have the faces texture turned on in the menu.
I’ve since tried to open earlier versions of Sketchup and they no longer work as expected (even on older drawings with materials in the drawing). I’ve deleted the current application and the older versions and gone into the /Library/Applications Support folder and ~/Library/Applications folder and cleared out all references to Sketchup and Google Sketchup. After reinstalling just 2015, the problem persists.
I don’t have any extensions nor plugins installed. Just the base application.
