I have Sketchup PRO 2015 & have just upgraded to Mac OS Sierra. It is now evident that there are issues wth the compatibility.
I have read the other work arounds but they do not work with 2015, would I assume then that I have to but 2016 or 2017 to get around this problem & why should I when I had a perfectly working piece of software??
All hel[p & advice gratefully received.
