For Mac Users, if the security warning pops up, try the following 2 options:

 1. open the file through Right Click -> Open insted of double click, sometimes there pops up an option like "Open Anyways"

2. go to System Preferences -> Security -> General -> (bottom left) "Click the lock to make changes" and change "Allow apps downloaded from" to "Anywhere".
