That is because there is no 32-bit version for Mac in CS6 and higher versions.
The only recent version of Photoshop and Bridge for the Mac to have a 32-bit version was CS5.x. Starting with CS6 both applications are 64-bit only.
CS4 for the Mac was only 32-bit, as the first version to have 64 bit version for Mac was CS5, unlike Windows versions.
