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 application extensions in macOS Sierra?
In macOS Sierra, application 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 application extensions?
Once they are installed, how do you manage application extension visibility?
Application extensions are installed automatically because they are bundled inside the application providing the extension.
You can enable or disable installed application extensions from the 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 macOS?
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
- 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-clicking (or Control-clicking) the application’s icon
- From the /Applications/Utilities/Activity Monitor application
What does the diagnostic reporting feature do?
The diagnostic reporting feature automatically springs into action whenever 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 at the Mac App Store.
