Thanks to this thread on the ArsTechnica boards, one of my nagging criticisms of OS X can now be addressed. If, like me, you prefer a mouse that moves at warp speed, you can hack the speed in both 10.0.4 and 10.1.
Using a terminal, edit the .GlobalPreferences.plist file in your ~/Library/Preferences directory. If you're using Pico, for example, type:
pico ~/Library/Preference/.GlobalPreference.plistOnce the editor opens, use control-W to search for "scaling". You'll see a couple lines that look like:
[key]com.apple.mouse.scaling[/key]Note that I've used square brackets instead of angle brackets, due to parsing issues with HTML. Change the number in the "[real]" line to a higher value. 1.7 is the maximum you get through the control panel; I'm using 3.2 now and like it on my 1600x1200 screen. Values over 10 may not work; I tried "15" and it became "1.5". Save your changes (control-O in Pico) and then quit the editor (control-X).
[real]1.700000000000000e+00[/real]
