RCDefaultApp overview

RCDefaultApp is a Mac OS X 10.2 or later preference pane that allows a user to set the default application used for various URL schemes, file extensions, file types, MIME types, and Uniform Type Identifiers (or UTIs; MacOS 10.4 only). MacOS X uses the extension and file type settings to choose the application when opening a file in Finder, while Safari and other applications use the URL and MIME type settings at other times for content not related to a file (such as an unknown URL protocol, or a media stream)

RCDefaultApp also allows setting the application when digital cameras or FireWire webcams such as iSight are connected to the computer

What’s new in version 2.1

Version 2.1:
  • Added ability to ignore creator codes for extensions (MacOS X 10.4 and above).
  • Added IM selection (i.e. aim:// protocol) to the Internet pane.
  • Added Blank/Video BD (Blu-ray) and DVD Device to the Media pane on MacOS x 10.5 (Leopard and above).
  • Added Spanish localization.
  • Only show one version of an application on 10.4 and above, per system limitation.
  • Fixed bug with the File Types tab on Intel machines.
  • Improved discovery of existing settings.
  • Built with a 64-bit Intel binary to work with the Snow Leopard System Preferences.
  • Fixed a couple of other minor bugs.

Even SwiftDefaultApps seems to be flaky quite often and don't show many UTIs etc. There's another alternative "Duti" which is a CLI tool that does basically the same thing. https://github.com/moretension/duti/

There's a new open source alternative called SwiftDefaultApps that works in Catalina. https://github.com/Lord-Kamina/SwiftDefaultApps

Great App, unfortunately not working in Catalina 10.15. Could you please update the source code? Thank you!

Unfortunately, RCDefaultApp no longer works starting in Catalina, since it's not notarized and whatnot. Now looking for a replacement. :(
