Question 3

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

Answer 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.

Question 4

What are the advantages of application sandboxing?

Answer 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.

Question 5

What are the advantages of code signing?

Answer 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.

Question 6

Which items fall under the file quarantine system?

Answer 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.

Question 7

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

Answer 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.

Question 8

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

Answer 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.

Question 9

What three methods can be used to uninstall applications?

Answer 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
