Has anyone found a way to download the data from a Polar S520 to their Macintosh? VirtualPC is kinda useless. I am using a Powerbook. TIA, Mike

I don't think it's possible. See Training Software for Mac OS X (http://www.bikeforums.net/showthread.php?t=50601) for more.

You might want to check out TrainingLog (http://www.otag.co.uk/TrainingLog/index.htm). It now incorporates the work of the old HRM Reader X project.

I am using my 510 on my Mac running virtual PC 6. The trick for me was an external micophone to download the sounds from the monitor. You also have to increase the sensitivity on the Sound control panel.
