Answer 1

I figured that this python wifi library does not work on mac.

An alternative to do wifi scanning is using the tool that comes in mac called airports.

To start using the tool -

$ cd /usr/sbin
$ sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport

The airports -I flag is useful

Also just typing airports will open up the partly explicit manual page
