Hello Reader,
              Another week of fun and challenges! I'm really enjoying seeing all of you get into this and hope I find more time this week myself to do more testing. Let's face it most of us are still at home, so why not turn some of your downtime into DFIR research time! This week we move over to MacOS aka OSX.

The Challenge:
KnowledgeC on iOS is a jam packed knowledge resource, but on OSX it seems to be less used. 
1. What does each table in the KnowledgeC database correspond to activity wise
2. What data is logged  in each table
3. What data is not logged
4. Is there a similar datasource that would fill in the gaps?
