How to upgrade from sketchupro 18 to 19 or 20 with Mac os 10.12

I need help to upgrade muy sketchup pro 18 into 19 or 20 having Mac os 10.12.
Many thanks!


Your license was upgraded to SketchUp 2019 when it was released, because you were under support at that time. I got the license manager to send you your 2019 license, look for a new email that came in.

You can get the 2019 installer from this link:
