Can you scroll with an Apple optical mouse M5769?

That one has no scroll function, just single-click.

Most third-party mice have scroll wheels and at least two buttons. I use Logitech wired mice on all our Macs, but they are especially useful on our old PowerBook that does not have the "two-finger scroll" function of latter notebook trackpads.

I believe the first Apple mouse that had a track-wheel was the "Mighty Mouse" introduced in 2005. However, it was not a very good mouse based on problems reported here.

The current Magic Mouse is the first Apple mouse since the ADB mice went to the rest home that I can tolerate. It has a smooth surface that functions like the trackpad, so scrolling does not involve a mechanical wheel. Consider one of those if hubby's computer is newer (system requirements ore included in the link below):

Forgot to ask: what Mac does you husband have? This forum is for Macs built before 1998 and gets very little traffic. If it's newer, it will have a dedicated forum with more eyeballs on your question.
