If you have updated to macOS Catalina without first running the Automap uninstaller, then this will not run on the latest macOS. Due to this, to uninstall Automap please delete the following files from your system.
All of the files can be found in 'Finder'. To get to 'Mac OS', with Finder open, in the top bar go to:
'Go' > Computer > it may be called; Mac HD, Mac OS, or a name you may have given it.
If files are not listed, they may not have been installed or have already been removed.
Delete the following files:
Applications > Automap Server
Applications > Automap Uninstaller
Mac OS > Users > username > Library* > Application Support > Novation > Automap Universal
Mac OS > Library > Application Support > MIDI Device PLugins > Automap Mixer.bundle
Mac OS > Library > Audio Plugins > Components > Delete any plugins with '(Automap)' in the name.
Mac OS > Library > Audio Plugins > VST > Delete any plugins with '(Automap)' in the name.
Mac OS > Library > Audio Plugins > VST3 > Delete any plugins with '(Automap)' in the name.
*If you cannot see this, please click go at the top of the screen > Hold 'alt' on your keyboard (also option on newer Macs) > The 'Library' option should appear.
