Front 1

What are the requirements for purchasing applications via the
Mac App Store?

Back 1

The requirements to purchase items from the Mac App Store
are OS X v10.6.6 or later, an Apple ID, an Internet connection,
and authorization as a local administrator.

Front 2

In the Mac App Store, how can you verify which Apple ID is
being used for purchases?

In the Mac App Store, you can view the current Apple ID by
selecting Store from the menu bar. You can get further details
regarding this Apple ID, by selecting View My Account in the

Front 3

What are the four primary application environments
supported by OS X? Which ones require an additional
download and installation?

Back 3

The four primary application environments supported by
OS X are:
• Native OS X applications, which are created using Cocoa
• UNIX applications, which are primarily accessed via
Terminal
• Java applications, which work as cross-platform
applications
• X Window System applications, which run inside the
popular UNIX windowing environment
OS X doesn’t include the Java application or X Window
System runtime, so they must be downloaded and installed
after the OS X initial installation.

Front 4

What are the advantages of application sandboxing?

Back 4

Sandboxed applications are only allowed access to specific
items. They’re otherwise completely cut off from the rest of
the system, so they can’t cause harm. All Mac App Store
applications are required to be sandboxed.

Front 5

What are the advantages of code signing?

Back 5

Code-signed items include a digital signature that the system
can use to verify the authenticity and integrity of the
application or process and its resources.

Front 6

Which items fall under the file quarantine system?

Back 6

Any item downloaded using one of the built-in OS X
applications will be marked for quarantine. Third-party
applications may not mark downloaded items for quarantine.

Front 7

What three security options does the Gatekeeper system
allow? Which Gatekeeper option is the OS X default?

Back 7

Gatekeeper can restrict software to Mac App Store
applications only, or Mac App Store and identified developer
applications only (this is the default option), or any
application regardless of origin.

Front 8

What are the two primary traditional installation methods in
OS X?

Back 8

Traditional installation methods are generally categorized as
either a drag-and-drop installation, where the user simply
copies the application to the local system; or as an installation
package, where an installer process places the items on the
local system.

Front 9

What three methods can be used to uninstall applications?

Back 9

Three methods for uninstalling applications include:
• Open Launchpad, hold down the Option key, and click the
“X” button
• In the Finder, drag the primary application to the Trash and
then empty the Trash
• Use a custom-built uninstaller package
