The rar file won't open or the program won't start up? I sadly can't test mac version personally, but someone was kind enough to mention this for a fix if there's issues trying to fix the mac version.

Download fix command: Here
Place "Fix_Permissions.command" file in same folder as "tyranoscript.app" then double click it. (possibly right click or ctrl+click and choose open)
In terminal you need to give the script +X permission to run.
Should work after loading (give it some time! >.<" )
