Thanks for the replies.

Ah! That is sad to hear

I don't mind the KGS client, but it looks really arcane and I have had some (minor) qualms about Java

Of course to play on KGS that is the only option.. I am hoping SmartGo comes out soon with a Mac OS version.

I believe I'm running mac osx lion though.
Both kgs and igs clients may run on a mac for that purpose.
Same here. I used to play on IGS via Goban when I started learning go (but subsequently found KGS a much more conducive environment to learn from others).
Hmmmm...I am thinking Lion and ML should be similar enough to figure out if it's something specific to my installation. I don't have any issues viewing SGF files, but it always freezes whenever I try to edit an SGF file - like marking a position, marking a stone or adding a comment for a move. Have you encountered this issue on Lion ?
