Is there a mechanism I could disable to get rid of the dialog every time I run a new browser on macOS?


  • When does that pop up - after starting an app? If so which one? – mmmmmm Feb 6 '19 at 12:39
  • Never seen anything like that, except from a browser. Not sure this is a macOS dialog, possibly comes from Opera. – Steve Chambers Feb 6 '19 at 14:27
  • I run three different browsers concurrently and I think I have only seen that message once... Using Safari, Chrome and Firefox . And I'm switching between them or restarting them 5 or more times a day... – Solar Mike Feb 6 '19 at 15:37

    You were right guys. This is not the system that triggers the dialog - it's the browser. – Mikołaj Bonowski Feb 7 '19 at 11:04

For Opera (and possibly for all Chromium-based browsers) it's enough to run the binary with --no-default-browser-check flag.
