Fix Signing Process for macOS Builds #6244
Description
We need to fix the signing process for macOS builds.
Currently MacOS binaries are flagged as quarantined after installation, because we don't sign these with a Apple license (which we should purchase first).
The following tools should be used: appify to create the app and create-dmg for the DMG. Manual steps can be found in this gist: macOS build steps (note: this gist doesn't include signing steps).
