I highly recommend Scid ("Shane's Chess Information Database"). Here's a screenshot of the Mac version (more to be found at Softpedia):
It is completely free, has lots of functionality, and is fast (handles my 5.2M game database quickly and fluidly). I have only used Scid in its Linux and windows versions, not the Mac. But from what I understand there are ...
I agree that installing Windows via Bootcamp is a good course of action. You may also want to consider Hiarcs' Mac Chess Explorer:
It has many of the same functions as ChessBase, and is from a developer who has an excellent history of supporting his Mac products. The program works with .pgn files, so being able ...
For native OSX databases you're pretty much limited to SCID and Exachess unless you want to go the Parallels route and use windows software from there. You might be able to rig up WINE and run it on the later versions of OSX; not sure, never tried it.
In both of these you'll be missing the high-end features of chess base, such as the opening report. I'm not ...

I assume you want this so that you can train against the engine by playing the suggestion for black and then thinking about what to play as white?
Lichess allows this on their website. Set up a position in the board editor or analysis board, then pick "Practice against computer". If you like, it will even evaluate your moves as you go, telling you if you ...
asmFish is NOT the same as Stockfish, so the answer by Dave is wrong. If asmFish ever catches up Stockfish in patches, then it will find the best moves ~20% faster, as it is written in Assembly.
Here is an issue I opened to test basically the time fasmg did to compile asmFish. It was closed, however, because latest fasmg fails to compile asmFish. The latest ...
As it is related closely to this question (but please read my comment qualifying this also):-
I would like to add my post on setting up :
