Shredder is over fine, but less stable than the others (lots of java or something). It has a major problem for me. It can't deal well with databases with more than 2.000 games.
Scid has all the features, even those you didn't ask for. It is fast and has analysis features at the level of a statistics junkie. It has the most demanding interface; it takes some times to learn how to use and configure all the options.
Now it's up to you. You use test the two first. Scid is freeware.

I'd just like to point out that only the HIARCS engine is UB. The actual application is still PPC. However, it runs very well still on my Core 2 Duo MacBook Pro. The engine makes up for any lag from the actual application running under Rosetta. Honestly it's hardly noticeable that it's not fully Intel native.

Regardless, a huge thanks to the developer!
This is a great free chess game, I love that I can set the game to various level and that I can import pgn games.

Doesn't have the coolness factor of Chessmaster on a PC with all of the different theme boards, but solid on all of the features that matter. I'm impressed with resource utilization and not burning CPU like Chessmaster on Mac.

A nice touch is that, as well as a slider allowing the strength to be set as a number, there is also a drop-down box allowing it to be set as a (US) category (Class A-D, Expert, Candidate Master ...).

I notified the developer but received no reply.
Yeah, I know Sigma's free but, still. Most of the developer's of the free apps that I've tried have provided good support. I guess the developer doesn't giveashit.
Still, Sigma does play a mean game of chess.
