Microsoft launched the new Microsoft Edge browser for macOS (for now just a Chromium re-skin with some telemetry sprinkled in) so if you want to run it on your Mac you must either use the built-in installer (and get all the benefits of seeing telemetry data being sent to the cloud) or extract the package and copy the .app to /Applications.

Download the latest version from the Microsoft Edge Insider website.

$ pkgutil --expand-full MicrosoftEdgeCanary-76.0.167.0.pkg ~/Downloads/MicrosoftEdgeCanary/

If you have a different version, adjust the command line accordingly.

Browse into the newly created directory and copy the .app file.

$ mv "~/Downloads/MicrosoftEdgeCanary/MicrosoftEdgeCanaryUpdate-76.0.167.0.pkg/Payload/Microsoft Edge Canary.app" /Applications/
$ open /Applications/Microsoft Edge Canary.app

There are some scripts that are sending telemetry data to Microsoft and a send_event binary that sends data to https://self.events.data.microsoft.com/OneCollector/1.0/ using sudo. Also the installer uses sudo to register the app to get updates from Microsoft Auto Update.

Below are the preinstall and postinstall scripts for the .pkg, found inside the MicrosoftEdgeCanaryUpdate-76.0.167.0.pkg/Scripts directory.
