I m running the latest version of MACos (mojave) and i m using Sketchup pro 2018, I ve downloaded and installed the plugin. Fredo_Scale
When i restart sketch up the following note pops up: (you must install Libfredo6 version 6.9 or higher to run fredo6_fredoscale)
I ve checked and i do have the latest version of Libfredo6 8.7
But still on the extension manager the fredo_scale plugin shows with an outdated signature message.
I think i solve the problem , when install the fredo_scale directly from the sketch up warehouse it doesn’t work, only when download it from sketchUcation web site , now it seams to be working.
