I am using SU2015 Make on a Mac.
I saved an existing file as a template (File - Save as template...)
I chose this new template to be the default template (checked the box)
I created a new file (File - New) and, as hoped, the new file opened using the new template.
But now I want to adjust my newly created template.
The problem is that I can't find the location of the SU2015 templates either searching my computer or via multiple internet searches for assistance.
I did find a similar query about the location of the 2015 Materials folder which, I learned, is in Sketchup.app-Contents-Content-Materials which is only searchable by right clicking the App and choosing Show Package Contents. Sheesh!!
But I am not seeing anything similar... or anything at all, anywhere... regarding a Templates folder!

Where are the SU2015 Mac Templates and/or how can I open up my SU Templates to adjust and re-save them?

Thank you.
