Here again, the issues are not specific to Macs.

The View / Panels menu allows you to choose which panels are displayed. 
Maybe you accidentally unselected Analysis.

By clicking anywhere on the right side of the board, like you do when you 
have access to the cube but decide to roll instead of doubling.

The number of plies is the depth of evaluation lookahead.

At 0 ply, for a checker play, the program evaluates the resulting 
position after every legal move and chooses the best one.

At 1 ply, for the more promising 0 ply moves it considers the opponent 
response (for every of the opponent rolls), evaluates the resulting 
position, average on the 36 dice rolls and uses this instead of the 0 ply 
evaluations. This is slower but more accurate than 0 ply.

2 ply look one more turn ahead and so on. The "named" levels are :
- expert : 0 ply
- world class : 2 ply
- supremo : 2 ply but considers more 0 ply favourites than world class
- grandmaster : 3 ply

This is more complicated in practice, due to the possibility of a cube 
action between each of these moves, but the above is the general idea.

> How do I store game/match results?

I'm not sure what you mean here. You can save a match with File / Save and 
add its result (usually after analysing it) to a database with Analyse / 
Add match or session to database.

The second command adds some summary results in a standard database 
(sqlite, mysql or postgresql, see Settings / Options / Database) but there 
is almost nothing in gnubg itself to use this data. You would need a 
minimal knowledge of SQL and/or some third-party query tool.
