How do I know which applications are installed on OS X using Objective-C or Macruby?

Question

Could you tell me which object and which method I can use to get information about installed applications on OSX with objective c or macruby?

Answer 1

If you want to list all the graphical applications, you can use Launch Services . For a list of functions, see the link .

Do not manually list .app packages . This has already been done by the system, and you just need to request it. There is a command line program called lsregisterin

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister

Answer 6

Since this is a unix-like OS, there is no real way to tell what you installed (unless, of course, you control another application - then there are many ways to do this for obvious reasons).

Typically, applications fall into / Applications or ~ / Applications, but you can run them from anywhere, and not from these folders (as for a unix machine).
