I have an early 2011 MacBook Pro and I'm trying to use a Logitech Anywhere Mouse MX with it. It uses Logitech's Unifying receiver:
I use the mouse with my right hand and it seems to get very poor signal from the receiver. I can confirm this by getting a USB extension cable and basically relocating the receiver to the right side of the computer, next to the mouse. The mouse works fine on all of my other computers, such as Latitudes and ThinkPads, so I know the receiver isn't the problem. And there's no option to change the channel it uses in the software.
I assume this is due to the material in the case.
On top of that, Logitech's Mac software is pretty buggy too. It often scrolls when I click and scrolling is very jerky. I know this isn't the mouse, since I can reboot into Boot Camp and it's perfectly smooth and normal (with the USB extension cable of course).
Does anyone have any suggestions to fix this or for a Bluetooth laser mouse with a couple of side buttons? I considered a Razer Orochi, but I tried out a friend's and my fingers went numb after a bit. I didn't like the stutter due to it going to sleep after 2 seconds either.
