Wireless mouse mac

I use an Apple, but I just wanted to point out that most Bluetooth mice that come with USB adapters are also proper Bluetooth mice, meaning that they will work without using the provided adapter. They include the adapters because of the Windows market where, unlike the Mac market, the penetration rate of Bluetooth is pitiful. But if the device supports the standard Bluetooth mouse profile, which almost all of them do, then this is a non-issue.

What I would do: If there is a specific Logitech you like, search for it here. Logitechs are popular with the Mac crowd, and you'll probably find someone else who uses one. And you can either see from that thread whether it works without the USB adapter, or can PM that person and ask directly.
