The PloatLab port to MAC is very much complete. Part of SignalLab is also ported. Here is a screenshot of it in action ;-) :
This is also part of the work on porting Visuino to MAC so as you can see the work is underway :-) .
I hope to have initial downloads of PlotLab with the new MAC support available in the next few days. It also compiles and runs on Android, but some more work and testing is needed there...
