This mouse was initially bought for my work laptop and has been used in part on my 2010 MacBook. But now, on my 2012 MBP, It seems that no matter what software I install from the Logitech website, I end up stuck at the same point. The software asks me to insert the 'Unifying' device so it can detect it and then boom, nothing! It doesn't recognise anything and that's it. Mouseless. Has anyone used this mouse with a later-edition MBP? If so, what software do you have exactly?
