I have a 2012 mac mini I'm setting up. I've connected it to a new dell monitor I bought for it. I plug in the usb mouse and can get the pointer to move, but the click doesn't work. Any advice? I've read other posts and thought maybe it was my nearby imac keyboard or wireless mouse interfering, but I've turned them off & taken batteries out and still no click action.
Any other suggestions for what I might try or what might be wrong? I used a windows keyboard to login successfully, but still need a mouse to get into mouse/bluetooth settings in Control Panel. I'm trapped!
