A free and opensource NES emulator for OS X
Macifom is easily one of the best NES emulators for Mac OS X, and it's free and opensource! It's still being developed, but it's complete enough to let you play your favourite NES games on your Mac.
Official release installation instructions
Head over to the Macifom download page and download a file called macifom-v0xx.dmg
Then, double-click the disk image to view its contents (or have Safari do it for you automatically):
Next, just drag Macifom.app (it may just say 'Macifom') to your Applications folder, and you'll be ready to play NES and Famicom games on your Mac!
