RCDefaultApp2.1

Great App! Transmission has recently added Magnet link support into the latest nightlies, and there is no way(that I know of) to change the default app (from Vuze to Transmission). this app makes it super easy!

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. :(

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 !

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.

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.

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.

Great App! Transmission has recently added Magnet link support into the latest nightlies, and there is no way(that I know of) to change the default app (from Vuze to Transmission). this app makes it super easy!

I recently had some issues with the default application for segmented files. I remembered RCDefaultApp and installed the older 2.0.1 and my problem was solved. It's great to see this update. Thanks!

anybody figure out how to get nntp urls to map to google groups in the default web browser?

Hmmm.... in theory this would be a nice app. Changing default app in Finder for MP3s changes this for almost all MP3 files, but some files are still given the iTunes icon and starts iTunes when clicked. Unfortunately, this application crashed with no error after selecting VLC as default app for MP3.

Works great, does exactly as advertised and you can't beat the price!

I was going mad with iTunes opening every mp3 file I converted, and not being able to find where this action could be changed. Then I came across a post in discussions advising use of RCDefaultapp.. This is a 'must have' for those who want a bit more control.

Beautiful! Does just what it says, and gracefully... and its free!!!

This is exactly what I was looking for. Thanks! Very helpful. I was getting tired of having the wrong default app for certain files and having to individually change each file's default app.

Small and easy to use. Apple should really buy this panel to include in the next OS X release. GREAT work!

Great utility. Interface is clean and understandable. This should be a standard preference panel on Mac OS X!

Works like a charm! Highly useful, easy to use, and free! Couldn't ask for more and would highly recommend (as I've done often on the Apple Discussions) :-)

I am using OS X 10.4.4 and turned to RCDefaultApp (1.3) so that I could map News, RSS, ATOM, etc. to RSSOwl. Unfortunately, the preference still insists on using Safari, even after I have saved my changes :-(

Fantastic! I've been searching a long time for an app like this. Like many others have said: why the heck isn't this part of OS X?

'Q: How do I uninstall RCDefaultApp? Drag RCDefaultApp.prefPane to the trash. Any changed LaunchServices settings remain changed.' ...so which settings got changed by RCDefaultApp by 'default'? It's not ideal, having things changed that may not work right again as a result of the app.

after a while using it, it seems to have a few issues with Tiger. All of a sudden, iTunes has started to change the file type of every song it plays to Quicktime Movie. This is a problem. Nothing else was installed or changed and the mp3 and mpg3 file types had iTunes as their 'default' app. Safari will not hand off the ftp handler to Interarchy, perhaps because I had Interarchy installed first, but that's a problem. It worked fine before, and the handler is set properly in RCDefaultApp. I'll uninstall it for now and see if things clear up.

works fine in 10.4.2, hoping it doesn't interfere with anything Apple does in an upcoming update.

Perfect! Thanks! Now can someone please explain why this pref. pane is not part of the OS? In System 8.5 there was an Internet Preferences Control Panel... Did Steve got mad at it?

Works perfectly in Tiger. It's a "must have" utility/prefpane. Thanks! :)

Assolutamente da avere!!!

Thank you!

I've tried this little gem. Very nice! It's a great time-saver. Thanks to the author for this great, free app.

Really neat. Does what it says on the label.

Excellent app especially for fixing those pesky programs that want to hijack your documents. I have Acrobat 6.0, and it wants to open all my .pdf's by default. But it's a slow program, and I only need it occasionally. With this preference pane, I can set it so that all .pdf's open in Preview. Then, if I need to open something in Acrobat, I can just ctrl-click it.

Excellent! Should have been provided by Apple. Have now uninstalled MoreInternet & ParanoidAndroid. Thanks to all you guys who find & fix before us 'average' Mac users ever get hit.

RCDefault works just fine for me, also.

Works as advertised, doesn't crash System Preferences like MoreInternet does. Well done.

Why didn't I know about this thing sooner? Amazing! I've been wanting something just like this.

Excellent, easy to use, and free. I came across it on a discussion of the new help:// exploit. RCDefault App allowed me to quickly and easily disable help:// URLs. See http://bronosky.com/pub/AppleScript.htm for a harmless example of the help:// exploit.

Absolutely fabulous application. My "open with" drop down list is looking goood!!

This is an *excellent* little app. I don't know how i managed to live without for so long. :o)

Perfect!!! Exactly what i have wanted for ages on Mac OS X. Many thanks to the developper.
