I using Mac OS X 10.8.5. I was using Firefox driver for testing. I would like to use chrome driver too. I searched and all i got is chromedriver for Mac-32 bit.
There is no 64-bit version of Chrome for Mac OS X, thus you also do not need a 64-bit chromedriver. Just use the 32-bit one :) put the executable somewhere in your path.
