How would one enumerate the installed browsers on an OS X system from a local app. I would like to build something like choosy, but different (long story). However, I would like to enumerate all installed browsers on the system.
On windows, I can dive the installed browsers in the Default Programs registries, however, I don't believe there is a similar concept on OS X. Do I have to manually search through all the bundles & their info.plist files?
Those two functions return bundle identifiers; you can use
LSFindApplicationForInfo to find the preferred instance on disk of an application by its bundle identifier.
(Don't forget to follow the Core Foundation memory-management rules.)
Edit: In a comment on this answer, smorgan suggests
LSCopyAllHandlersForURLScheme(CFSTR("https")) (that's https) as an alternative to the first call. This is a good suggestion.
