Good morning,
this is the first time I write and therefore there may also be errors of tradition (use google being Italian).
I use an iMac, and after a long time I tried to use PI, but a very strange thing happened to me, the mouse didn't give me the possibility to click for operations or for inserting images. I tried to use a mouse for windows and everything was fine, as a final note I say that once I get out of PI the "mac" mouse works perfectly.
