After installing Karabiner Elements for MacOS I found that the Logitech Gaming Software (LGS) was no longer detecting the mouse and was showing the move mouse to wake dialog.
It took a while to figure out that the cause was the recently installed Karabiner Software, exiting the software allowed immediate recognition of the mouse. Not sure what the cause is and the mouse was functional though not under the LGS command.
A useful tool but not if you are using LGS it would appear.
ExactMouse acceleration killer:
ExactMouse from Steelseries removes mouse acceleration on the Mac.
Acceleration is a a problem for me when using a mouse on any computer that requires precise pointer placement. It is not easy to disable it completely on the Mac without using some fancy terminal command.
To make it easy to disable acceleration either term-rally or permanently you can use the ExactMouse tool from Steelseries. The improvement in general mouse work are subtle but noticeable and improve the feel of high quality gaming mice.
