Hello All-
I'm using SketchUp 2021 on a MacBook Pro running Catalina. I've tried to install Sketchucation Tools several times and get this message when I open SU.

Error Loading File SketchUcation.rb
Error: #<Errno::ENOENT: No such file or directory - getcwd>
/Users/name/Library/Application
Support/SketchUp 2021/SketchUp/Plugins/
Sketchucation.rb:61:in 'pwd'
/Users/name/Library/Application
Support/SketchUp 2021/SketchUp/Plugins/
Sketchucation.rb:61:in 'Module:SCF'
/Users/name/Library/Application
Support/SketchUp 2021/SketchUp/Plugins/
Sketchucation.rb:17:in 'top (required)>'
I have Sketchucation Tools successfully installed and running on a windows machine. Is that the issue? Am I only allowed 1 seat of SCF at a time? If so, I understand and will comply.
Thank you!

I'm running into palettes that are no longer "sticky" since upgrading to Mavericks. To be more precise, although the palettes do snap to one another, when expanding one such as the Layers palette, it opens underneath the minimized Styles, Scenes, etc. instead of having those palettes remain connected to the Layers pane. When minimizing them down to their title bars, they can also lose their relative association to other palettes.

ME Too!
