Well, since there still is no application that can produce .mbm files with a Mac, I did find something that was good enough for me... the communicator itself!
Let me explain:
There is no tool that can make mbm files on the Mac, but I wanted to make some smart-secure login screens... now I only make the designs as .jpeg, and put them on my MMC, I open the jpeg with my communicator and then choose the option "save as". There I can change the file type from jpeg to epoc. Those files can then be used as .mbm files
I have not found a way to make multi-layer .mbm files for the right side of the desktop... but it's a start!
