Lesson 18 - Manage and Troubleshoot Applications Flashcards
Why would you want to open an application in 32-bit mode?
Using the Finder Info window, you can force an application to open in 32-bit mode. This step is necessary for a 64-bit application to support older 32-bit plug-ins or application resources.
What four types of capabilities can be added via app extensions in OS X El Capitan?
In OS X El Capitan, app extensions allow features from an application to extend into the Action menu, the Finder, the Sharing menu, and the Today view in Notification Center.
How do you install new app extensions? Once they are installed, how do you manage app extension visibility?
App extensions are installed automatically because they are bundled inside the application providing the extension. You can enable or disable installed app extensions from Extensions preferences.
How can you identify which applications are installed on your Mac?
You can use the System Information application to easily scan all the appropriate application locations and return a list of installed applications.
Which application is used to examine open applications on OS X?
The Activity Monitor application is used to monitor open processes and applications.
What steps should you use when troubleshooting application issues?
General application troubleshooting steps include restarting the application, trying another known working document, trying another user account, checking log files, deleting cache files, replacing preference files, and replacing application resources.
In what three ways can you forcibly quit an application from the graphical interface?
The three ways to forcibly quit an application from the graphical interface are from the Force Quit Application dialog, accessed from the Apple menu; from the Dock application shortcut menu, accessed by secondary (or Control-) clicking the application’s icon; and from the /Applications/Utilities/Activity Monitor application.
What does the diagnostic reporting feature do?
The diagnostic reporting feature automatically springs into action anytime an application crashes or hangs. This process creates a diagnostic report log that can be viewed immediately, reported to Apple via the Internet, or viewed later in the /Applications/ Utilities/Console application.
Where are application preferences stored?
Application preferences are almost always stored in the user’s Library folder in the ~/Library/Preferences folder. Newer sandboxed applications must always store their preferences in a ~/Library/Containers//Data/Library/Preferences folder, where is the unique bundle identifier for the application.
What file format is often used for preference files? How can you view the content of this type of file?
Most application preferences are property lists, which are XML-formatted files that use the .plist filename extension. The content of these files can be viewed using Quick Look and edited using the Xcode development application found on the Mac App Store.
