macOS 10.15.4 Legacy System Extension signed by “Jack Lo”

Message: Existing software on your system loaded a system extension signed by “Jack Lo”.

In my case this is the Evoluent Mouse Manager software v1.4.1 accessed in System Preferences.

Evoluent say that they are working on a replacement, let us hope they complete it before macOS 10.16 when the existing version won’t run any more.
