Hello, I've just gotten hold of an Intel Mac Mini secondhand from eBay, which came with a wired keyboard and a wireless mouse. Very happy, but my one problem is that I can't get the mouse to work at all. It's the old wireless mouse, not a mighty mouse. I've changed the batteries, checked that they're in the right way, but I don't get a light on the bottom of the mouse when I turn it on, and my Mac can't see it at all when trying to pair in Bluetooth. Any ideas as to what I'm doing wrong, or have I just been given a duff mouse? Thanks in advance for any help, Regards, Mark.
