        Please explain a little more...
        What can't you get to work ?
        Open the Window > Ruby Console.
        Select a group or component instance that has a volume - we are trying to find it's C of G !
        Run the tool and answer the dialog's questions...
        What happens / doesn't happen ?
        What are the messages if any in the Ruby Console...
        There is nothing different between a PC and a Mac for this tool [except 'PEBCAK' πŸ˜‰ ]

            I just installed it on my MacBook and tried running it. It worked fine for me. Thank you TIG.

              Have you got deBabelizer.rb in the Plugins Folder ?
              This file is for translation and is used by many of my tools and it ships with each of them - although it's always the same file...
              It should come with the zip and is installed into the same folder as CofGravity.rb ?
              The error is because 'db' which is the local def of deBableizer in the class is failing to get defined...

                Hi Tig,

                I only installed it to send you a report from another Mac, and am sure I used all of the correct instal procedures.

                your other tools are still working (EEby.., Manifold, Vol..2) , after the CofG_1.2 instal (including deBalelizer.rb)

                after the first (_1.2) Error, I replaced both files with the _1.1 files and had the same error.

                I then tested all in the same drawing
                EEby Rail--worked
                Volume2 --worked
                Manifold --worked
                CofG --same error report (-1.2 re-installed from zip)

                john

                  A mystery... πŸ˜• πŸ˜’

                  
                  def CofGravity;;calculate ### LINE 129 ==start of class/def that is reporting the error...
                  
                  def db(string)
                    dir=File.dirname(__FILE__)+"/TIGtools"
                    toolname="CofGravity" 
                    locale=Sketchup.get_locale.upcase
                    path=dir+"/"+toolname+locale+".lingvo"
                    if not File.exist?(path)
                      return string
                    else
                      deBabelizer(string,path)
                    end 
                  end#db
                  
                  if (Sketchup.version.split(".")[0].to_i<5)
                       UI.messagebox(db("C of G; Sorry, this is Version >= 6 Tool !"))
                       return nil
                  end#if
                  
                  model=Sketchup.active_model
                  entities=model.active_entities

                    model.start_operation((db("C of G")),true)### LINE 153 GIVES ERROR !!!
                  
                  

                  Can you look at the script's contents and see if it looks like this ?
                  Works fine on a PC for me - can't see where a Mac might trip up ?

                    Need to require 'dBabelizer' before you use it.

                      That's it ! Thanks.

                      Other tools requiring it were masking the fact I missed it out of the initial 'require'... πŸ˜’

                      Update on it's way !!!

                        that appears exactly the same,
                        the only thing that seems at odds is the syntax colouring for calculate shows it as a variable??
                        I don't know enough to know why, or where to look next

                        this is odd...

                        I'll send this even if the missing "require" is at fault, because I don't understand why one and not the other would be a variable....

                          http://forums.sketchucation.com/viewtopic.php?p=229404#p229404
                          The initial 'require' of deBabelizer was accidentally missed out, but its absence was masked by some other tools loading it anyway so most times it worked anyway...
                          Now it is explicitly called for in the tool... πŸ˜’
                          Sorry for the confusion...

                            seems to have something to do with it...

                              Have you got the recent v1.3, with the require 'deBabelizer.rb' added ?
                              This should fix it ?

                                If calculate is a reserved term in Mac Ruby versus PC I'm surprised...
                                You can edit the file and change every ' calculate' to say ' do_calculation' and see if that helps - if so let me know asap πŸ˜• πŸ˜• πŸ˜•

                                            BUT as we can all see it is defining db as a method inside the particular class::def and then using it - the way it's used loads of times in other tools too... It works fine on PC so what is so special about a Mac ?
                                            Puzzled... Any Mac scripters have any ideas ??? ❓ ❓ ❓
