Uninstall Evoluent Mouse Driver
Problem
Evoluent’s official driver doesn’t work in my friend’s macOS Catalina 10.15.5. Therefore, I recommended SteerMouse to him.
However, he couldn’t uninstall the Evoluent driver from the icon in System Preferences, which blocked him from installing SteerMouse :(
After some research and the reading the error message from SteerMouse UI, we figured that we had to unload the Evoluent driver(a kernel extensions) by
sudo kextunload -b com.evoluent.driver.VerticalMouseDriver
Then SteerMouse can correctly detect his Vertical Mouse (a green light icon)
Remaining issues
We still don’t know how to completely remove Evoluent’s mouse driver yet. What we have done so far was removing all files in com.evoluent.pkg.Installer but this effort was to no avail.
# List all installed *.pkg
pkgutil --packages
# Check the files in evoluent pkg
pkgutil --files com.evoluent.pkg.Installer
