One thing to check is whether the binary file has been successfully copied.

Could you do the following in SU2019

1. Open the RubyConsole

2. Type File.join(Sketchup.temp_dir, 'Fredo6_LibFredo6_TemporaryFiles')

3. The console should display the result, something like
   /var/folders/6_/9kz2gk_x7b70xbzsq4ghcpt00000gn/T/com.sketchup.SketchUp.2019.johnthorp/Fredo6_LibFredo6_TemporaryFiles

4. Open the Finder and use the menu Go > Go to Folder (or Shift-Command-G) and type the result of the previous step in the prompt dialog

5. If you open the directory in the finder, could you check if there is

   • a subfolder: binaries
   • and within it a subfolder SU19 with a file bin_LibFredo6.bundle

If there is no file, then we have the explanation. This might be a problem of security settings.

If there is a file, then this is another problem.

The same problem. But in the folder Binaries\SU19 i have a file bin_body_Lib6G6.so
