Fixing the tracking speed of a Logitech V270 on Mac OS X

I recently bought a Logitech V270 Bluetooth mouse. I like it, but I ran into a problem with tracking speed. The lowest setting is far too slow, and the next highest setting is far too fast. After some Googling and hunting around, I found the fix. It seems that while the Tracking Speed slider doesn’t get the job done, we can set the value directly in the preferences.

$ defaults write -globalDomain com.apple.mouse.scaling 0.03

I fooled around to find a good value, but this seems to be good for what I want. Setting the slider all the way down sets the value to 0, and the next notch up sets it to 0.125.

has anyone figured out a way to configure the wheel button?

Configure how? I rather like it as the middle button, myself.

This cmd doesn’t work on my MBP. Regardless of the value I use, the mouse moves the same. Ideas? I tried as regular user and as su.

I recommend the application Mouse Zoom.

The terminal method didn’t work for me, but this app does.
Bye!

no luck with the command line and mouse zoom affects only the trackpad on my MBP, not the bluetooth mouse :(

I just did the following in Leopard and it worked …

1) As a non root user run …

defaults write -globalDomain com.apple.mouse.scaling -float 0.03

2) logout and log back in
