How can one add a new MIME type in OS X?
2 Answers
The easiest would be to download and install RCDefaultApp. Go to System Preferences » Default Apps, then the MIME Types tab.
Enter your new MIME type in the text box below, press the + button, and select your handler.
Via command line, you need to edit the ~/Library/Preferences/com.apple.LaunchServices.plist
preference list. In its array of LSHandlers
, you need to insert a Dictionary
containing your new MIME type as:
LSHandlerContentTag
– the MIME typeLSHandlerContentTagClass
, which ispublic.mime-type
LSHandlerRoleAll
, which specifies the Bundle ID of the application that handles it, e.g.org.videolan.vlc
. You find out the bundle ID by inspecting the.app
folder and theInfo.plist
preference list therein.

Is there a way to do the same from the command line? Possibly by editing
mime.types
?– JAMMay 8, 2012 at 13:38 -
See my updated answer. Are you talking about
apache2/mime.types
? Not sure if you're supposed to edit that. Can you elaborate a bit why you need to edit it? What's your context? Without context, it's hard to help you.– slhckMay 8, 2012 at 14:59 -
Awesome answer... Wondering if you were aware of which apps might add in this way? I see none in my
LSHandlers
that use this format.... Is that becauseLSHandlerContentType
(with values like "public.css" instead of "text/css") is preferred for this? ( apple.stackexchange.com/a/9883/206073 seems to suggest such a preference, at least in the case of comparingLSHandlerContentType
to the "public.filename-extension"LSHandlerContentTagClass

1@BrettZamir Good question – that's beyond my knowledge. It could also be that the default has been changed in the meantime (my answer is from 2012).– slhckJun 21, 2018 at 5:33
