Mac OS X Leopard - ARCAism

Depending on the package, the options available to you will vary greatly, but generally the
Custom Install screen will let you add or remove optional components to/from your install and
may also provide a column to customize the installation folder on the selected install volume
(otherwise, the default install will be either directly in the Applications folder or in a subfolder in
the Applications folder).
Whether you choose the standard install or custom install, once you click the Install button,
the installation will begin.
When the installation is complete, you will often be presented with a screen letting you
know that your installation was successful.
NOTE An application package, like many applications, is actually a bundle of various pieces.
To look inside a package, select Show Package Contents from the contextual menu. One particularly
interesting file you will find inside is the BOM file (usually called Archive.bom). What’s
interesting about this is that it contains a listing of all the application parts and where they go.
To view this information, use the lsbom command-line tool.
File Dialogs: Opening and Saving Files
One common feature found in most applications is the file dialog. This window (and variations
of it) is used throughout the system, primarily for opening and saving files.
The simplest file dialog is often used to open a file (Figure 13-6). Essentially this provides a
mini-Finder view to browse the system and select the item you want to open.

When you want to save a file, the file dialog is a bit different. The first difference is that the
Save As dialog has a simple view (Figure 13-7) and an extended view (Figure 13-8).
