I have Razer DeathAdder 1800, Apple Magic Mouse and Logitech M705 and after switch from PC to Mac I noticed very strange mouse behaviour. Apple Magic Mouse is uncomfortable for long work in Photoshop or illustrating so I'm trying to get the best from DeathAdder which was perfect in Windows, precise and very comfortable. I red about mouse acceleration problem with OS X and wonder is there any setup that works with DeathAdder? I've also tried Logitech M705 and it's much better than DeathAdder and Magic Mouse but i like Razer more than those two. EDIT: I was unable to setup DeathAdder to work like I would so I played with M705 settings and it's quite good after changing some preferences.
