Bitmap to Mesh

[maxjayok]

Hello,

I'm trying to import drawings and, using the Bitmap to Mesh extension, create a mesh from which I can begin to make a 3d drawing.
I'm fine to import the bitmap but I can do nothing with it. Can't 'right click' (Mac) to find an option to create the mesh. Every instruction video I've seen uses menu options I can't see in 'my version' of the software (Mac and Make (free)).
Am I missing something?
Is there a more effective way to realise this project?

Thanks in advance guys.
