Simple Ruuvitag python lib now supports Mac OS, if you use python 3.
There are, however, some limitations: Mac OS does not support mac addresses on advertisement, but the RAWv2 data format contains the mac address of the tag, which solves that problem. This means that for mac you will only receive data from RAWv2 sensors.
Also, the library is now also published on pipy, so to install just use
pip install simple-ruuvitag
“This works on my machine” so if others can test it out and report problems in the issues section, that would be great: https://github.com/ruuvi-friends/simple-ruuvitag
