SCID, SCIDvsPC, Lucas Chess, and Arena can all do this. I personally prefer Lucas Chess.
Chess software that will analyze a multiple games in a PGN file??

I'm not sure if it runs on Mac, but Komodo by Kaufman is a very very strong engine and is free to the best of my knowledge. I'm not sure it will analyze the game and give annotations, but it is one of the strongest engines if you are willing to look through the games yourself.
I have a bunch of my games stored in a PGN file, and I would like to have a (quality) computer program munch on them and just give me the results, minimal annotations required, like inaccuracy/blunder/etc..
Please don't recommend the chess.com computer analysis feature. Plainly, it sucks. After 1.e4 it says c5 is an inaccuracy, give me a break. I'd like the program to have a reasonable opening book, and endgame tablebases.
Anybody know of anything like that?
Thanks,
Seth
