Mimio Studio needs to be updated for macOS Mojave, their software isn't signed so that a PPPC/TCC profile can be created. I've been waiting on an update for a handful of users. I'm not confident Mimio knows what they need to do though because this is in their latest release notes:

** Version 10.14 Mac OSX requires special permissions for MimioStudio apps (under
System Preferences>Security & Privacy> Privacy >Accessibility) as MimioStudio is
not a 64-bit application.

Link to their release notes.

bumping this to see if anyone is actually using this.
