To have that kind of problem with two completely different mice. To be honest, I'm wondering if the problems in the OP are hardware related at all. Don't currently have the drivers/bloatware installed for either of them (though they were useful for initial setup of the firmware on the G700), use the G5 on both Win and OS X. I also use Logitech mice, a G5 at work and a G700 at home. So do you have a recommendation for a good 3 button mouse that works on Mac? At this stage I'm not sure what to seek and am using my disconnects-every-5-minutes magic mouse which will never suffice in the long term. It was $50 and is going back for refund tomorrow. As a bluetooth device my mouse teleports across the screen in 3 inch jumps. So I went to the apple store, and brought their recommendation, a 'Rapoo' model with both bluetooth and a USB connector(still wireless) but my mac thinks the usb thing is for a keyboard not a mouse. Also no middle mouse is pretty much ridiculous for 3d modelling/navigation. Apparently a common issue - Apple has never made a decent mouse in my experience, and their best one is no exception.

I fired up my crappy magic mouse and as well as actually not having a middle mouse it disconnects (bluetooth) every 5 minutes for up to one minute where it just doesnt work. Sometime during the frustrating accounts process I gave it the bash and as a result the middle mouse no longer worked and now I need to find a replacement, ideally something that works a lot better. I'd never really noticed, had been used to it.

I went back to 3d modelling and noticed that I'd always put up with this, hand often tensed up, battling the mouse to go exactly where I want it to. I looked closer and when I move it slowly diagonally it would sort of go 5-10 pixels across then 5-10 pixels up, so what should be a straight angled trajectory on the screen in practice traveled like stairs/steps viewed in profile. When doing accounts recently, my spreadsheet had tiny columns and I noticed I was having trouble getting my no-name USB mouse to go to exactly the right area of the screen.
