Rcdefaultapp big sur1/2/2023 ![]() ![]() Using jakeheis' SwiftCLI 2.0 as a base for the CLI version located inside the bundle. ![]() Mdls -name kMDItemContentType -name kMDItemContentTypeTree -name kMDItemKind my_song.mp3 Acknowledgments & Attributions Run in your terminal the following command (replace my_song.mp3 by your file): Why? Because new schemes are by default associated to *"Do Nothing", which means Launch Services will always find a valid handler as long as SwiftDefaultApps is installed. As a further cautionary note: If you add a custom URI Scheme when it is not needed, you may not be able to remove it except by uninstalling and reinstalling SwiftDefaultApps. This options is provided for completeness' sake you should virtually never need to use it, since Launch Services should be able to properly detect any valid URL Handlers. One final note: In the URI Schemes tab, you have the option of adding a custom URI Scheme (Removing them on demand is neither possible nor necessary, due to the same thing explained above).In practice, what this means is that although you can choose any application to handle anything, only valid associations will be preserved, as the LaunchServices is permanently looking for invalid or stale associations and removing them. In recent versions of macOS, the LaunchServices have become quite a bit smarter under the hood than they used to be. ![]() The second is "Other.", which obviously will allow you to select an application not in the list with a caveat.By default this application should be located in the Resources folder inside the prefpane bundle SwiftDefaultApps will, however, also look for it in the directory it is itself located in (for the CLI version) and every Applicationsfolder in the computer. Its only function is being able to open any URI Scheme or UTI whatsoever, printing a line to the console (specifying whatever it was that launched it) and immediately quitting. One of them is "Do Nothing", what this does is register the item to be handled by a dummy application which basically does nothing.This data is generated by LaunchServices itself. Selecting any URI Scheme or File type (always represented by a UTI), will give you a list of all valid applications for each LaunchServices role.The user-interface should be pretty self-explanatory but, there are some things that might require an explanation: This Preference pane will let you view and change default application associations for basically any URI Scheme and/or filetype in macOS. ![]() ` ` `shell # If, when you installed the Preferences Pane, you only installed it for the current user, # replace /Library with ~/Library in the two commands below # Remove quanrantine flag xattr -r -d /Library/PreferencePanes/SwiftDefaultApps.prefPane/Contents/Resources/ThisAppDoesNothing.app # Open the app open /Library/PreferencePanes/SwiftDefaultApps.prefPane/Contents/Resources/ThisAppDoesNothing.appĪfter these 2 steps, the Do Nothing app should work when you pick it up. For this, open a terminal and run the 2 following commands: :warning: The **Do Nothing ** dummy app needs to be launched before to use it in the pref pane. It will open the system preferences and you find the app on the bottom of the icons. ` ` then use Spotlight to open the `SwiftDefaultApps.prefpane `. ![]()
