I hadn't missed the toolbars!
It is possible to get PE6 running on OS X (Mavericks) using Wine. It is a bit of a pain to set up, but is possible.
Unless I want to use the (excellent) simulation features of PE6, I prefer to use Mac AxePad. If I need the simulation features I would generally load up Virtual Box (Running Windows XP) as this is far more responsive than running it under Wine.
One of the things I particularly like about the PicAxe processors is the superb simulation offered, much easier to write some code and then check it in the editor by running it than it is to program a chip, put the chip into a circuit start it, test it, guess where the error(s) are, take it out, write the code properly, program the chip, put the chip in a circuit...
Ideally I'd like a Mac version of PE6 with the full simulation facilities, but if all else fails, Wine (the program) and Virtual Box come to my rescue.
