RCDefaultApp

I'm on Big Sur. How do I remove or uninstall RCDefault?

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. :(

For osx >= 10.12, https://github.com/Lord-Kamina/SwiftDefaultApps

This is a great System Preference Pane which allows you to select the default app for many files types. Unfortunately, it was last updated to version 2.1 on September 2009. That is EIGHT YEARS AGO. Hopefully it will continue to work with the next MacOS 10.14 due September 2018. This version only allows 64-bit apps to work. 32-bit apps will no longer run. The developer listed this app as a 32/64-bit Universal app. So cross your fingers.

Despite all the changes to OS X since 2009, RCDefaultApp still works fine, and still provides useful functionality. I don't need to use it often - but when do need it, I'm very glad it's there.

Excellent !

Unfortunately this wonderful tool, which worked beautifully all the way up through El Capitan, doesn't work at all on Sierra (Golden Master). It has to do with old-style garbage collection. If you try using the `lstool` binary buried inside at the CLI, you'll see that Sierra won't even let it run. `lstool` is what does all the work, IIRC. Of all the things that I'm losing because of Sierra breakage, this is the most painful.

Sophos reports that the 2.1 update contains "Adware or PUA InstallCore" and blocks the install.

This has been a useful utility for a long time. Glad it still works. Oh, and if you get worried about the included "DoNothing.app" security warning, there's an easy fix. Go to (either your user or the top-level Library, depending on whether you chose All Users or just This User when installing): /Library/PreferencePanes/RCDefaultApp.app Right-click on it and choose Show Package Contents, then go into Contents/Resources/DoNothing.app. Right-click on that to choose Open - that will ask you to confirm that it is OK to be opened. Here's an explanation of what it is for, from the FAQ, in case you missed it: "As mentioned in the README, "disabling" an entry actually assigns it to a dummy application contained within RCDefaultApp.prefPane called DoNothing.app. This application will launch for a few seconds in the background, and then exit. This is done because LaunchServices does not allow an entry to be truly disabled."

Love this little helper! I've been using it since forever and I'm still waiting for it to fail even the slightest…

Exceptionally useful. I still find myself using it in 10.9.4 regularly.

download seems no longer available :-) Anyone can upload or send me the app please?

For more years than I can remember -and I won't even count how many OSs- this wonderful little gem still works! I mean... it's late 2013... am runnin' 10.8.3 Mountain Lion... and it still works!! Further, the Apple method via "Get Info" just doesn't always work (had the same trouble users below had) which makes this tool invaluable.

This little gem has worked for years and has helped me easily change default applications for extensions, et al., quickly and painlessly. From OS X 10.2 to 10.7, it worked without issue. But with MacOSX ML, it seems to have broken, I suspect it's related to GateKeeper potentially (just a hunch). I would love if the application could be updated for continued use; but sofar, though it installs, I can't change default applications with anymore. I have emailed the developer and asked if RCDefaultApp will be updated to work with ML; I hope; but understand if it isn't. A great application though nonetheless for anyone using OS X 10.2-10.7.

Excellent app! The only way I know to change URLs like “tel”.

Just downloaded and installed to get control over which program was opening .flv files. Mission accomplished. Provides great control over what applications open what files. Easy interface. Good work.
