I wanted to stick with Zsnes because I'm a really sloppy player and I like having rewinds, which Snes9x doesn't have.
Zsnes is overall very unstable and many games can not be played in it. You'll either need a more accurate emulator for those games or to just not play games which zsnes cannot.
If you like rewinds, you should look at retroarch. Heres a video which demonstrates its real time rewind capabilities:

Note: SSNES is the old name, it is now known as retroarch. Retroarch is a multi-console emulator and uses snes0x or bsnes (user choice) for SNES emulation. It should work fine on a mac, though I do not have installation instructions handy. There may be precompiled packages around somewhere tough, you'll just need to look around.
