Oh gawd. The original hockey puck mouse was absolutely TERRIBLE to use! I'm glad Apple designers came to their senses and came out with better mouse pointers, though they avoided the use of multibutton mouse pointers until only fairly recently with their Mighty Mouse pointer. Fortunately, recent versions of the MacOS supports third-party mouse pointers through the USB port, so most of the modern mouse pointers you can buy from Microsoft and Logitech do work under MacOS X with the right software driver, even high-end models like Logitech's MX Revolution and Microsoft's Wireless Natural Laser Mouse 6000.

Recent versions?

Macs have supported right click via USB mice since before OS 9; when the original iMac came out in 98, it used USB and supported the right click on non-Apple input devices. It ran 8.1.

That was more than 10 years ago.

And since the 80s with the Apple Desktop Bus.
