macOS App Directories

Xojo example project

Description

An example Xojo project to show how to deal with application directories on macOS. Why that?

macOS Catalina (and newer) consists of two Volumes:

1. a read-only System volume
2. a read-write Data volume

So the classic /Applications directory is now the one where users can store their system-wide available applications. Apple's own System Applications will be in another location. Finder transparently shows them just as Applications. However, Developers might need to get the correct native path. But Xojo only provides a single folder using SpecialFolder.Applications...

The included examples show how to:

• Find Applications
  • by BundleID (the preferred way)
  • by AppName (this will try to find it in all possible system defined application directories)
• Get an Array of standard/default Folders defined by Apple (see the Enumeration: NSSearchPathDirectory).
  • This way you will get all ones (also the per-user Application Folder, if it exists) from the OS.
• Get an answer to the following questions:
  • Which available application(s) can open a Document?
    An example is included which will ask you to select a Document. It then locates all suitable Applications, depending on the LSRolesMask(s) you specify.
• Which available application(s) can deal with a given URL?
  • Another example locates Applications that can deal with any given URL (e.g. list all WebBrowsers).
