I've been looking for and had to learn that not every Mouse sends 2.4GHz, also a Bluetooth Mouse.
No, unfortunately not.
I think it's again a matter of protocol.
Bluetooth is an invention of ... God knows by whom
.... But who invents, who must sell the license or the protocol.
Now it seems to be so that many manufacturers write their own protocols and save the royalties.
Anyway. Back to Mouse.
The Mouse is now recognized by the Mac.
All keys will operate until the side buttons on the mouse. The for me only in the browser "Firefox" can be used.
Unfortunately it is a bit small. There are apparently no major Bluetooth Mouse.
Nevertheless, it is thanks to their super good form in the hollow of his hand.
It appears no battery level in OSX.
