It's more than whether an app is signed. Apple now requires signed apps to be submitted for approval ("notarized"), and some open source developers take an understandably dim view of this.
Some forums suggest that software that's already installed on a Mac may run after upgrading to Catalina, but if you have to re-install the software or install an updated version, it may get caught by Gatekeeper if it's not signed
and notarized. Plugins also appear to be affected depending on how the host app is notarized.
The question is whether there is an option to override Gatekeeper, as there is with High Sierra.
pwalker8, are you confirming that it is not possible to override Gatekeeper in Catalina?
Thank you
