Ok so I have updated my 2010 iMac to v10.6.8 and now my Magic Mouse randomly spazzes across the screen or is very slow to move. I have installed the supplemental update in the hopes of fixing the problem, also reset the PRAM and SMC, all to no avail. I've seen quite a few threads about this issue for Lion users, but have yet to come across one specifically for Snow Leopard users.
If there is one and I'm just being blind, please feel free to point me in the right direction.
If there isn't and there's something else someone with better knowledge of this kind of thing than I have can suggest, by all means let me know.
