Lesson 20—Manage and Troubleshoot Apps Flashcards
What is a Universal app?
Developers can compile their apps for both Mac computers with Apple silicon, and Intel-based Mac
computers. The resulting app is called a Universal app.
What is Rosetta?
Rosetta is a translation process for Mac computers with Apple silicon. With Rosetta, a Mac with Apple
silicon can use apps (and other kinds of code like plug-ins, add-ons, and extensions) that were created
for Intel-based Mac computers and not updated for Apple silicon.
How do you install Rosetta?
If macOS detects that the code you’re trying to run hasn’t been updated for Apple silicon, macOS asks
you to first install Rosetta. Just click Install in the dialog. You won’t need to install Rosetta again.
What functionality do app extensions add to macOS Big Sur?
App extensions let apps from different developers interact with each other in such way that one app’s
features appear that they are built into the other app.
How do you install new app extensions? How do you manage app extension visibility after they are
installed?
App extensions are bundled with the app that offers them, so they install automatically. You can enable
or disable installed app extensions from the Extensions preferences.
How can you identify the apps that are installed on your Mac?
You can use System Information to scan the appropriate app locations and return a list of installed apps.
In macOS Big Sur, what app do you use to examine open apps?
- Use Activity Monitor to monitor open processes and apps.
How can Activity Monitor help you identify if a Mac has sufficient physical memory for the task?
Activity Monitor uses the Swap Used and Compressed memory statistics to display the historical
memory used since the last startup. A low swap value is acceptable, but a high value indicates that a
Mac doesn’t have enough real memory to meet the app’s demands.
Which steps should you take when you troubleshoot app issues?
Use these general app troubleshooting steps:
a. Restart the app.
b. Open another known working document.
c. Try another app.
d. Try another user account.
e. Check diagnostic reports and log files.
f. Delete cache files.
g. Replace preference files.
h. Replace app resources.
Which three ways can you forcibly quit an app from the graphical interface?
The three ways to forcibly quit an app from the graphical interface are as follows:
• From the Force Quit Applications dialog
• From the Dock
• From the Activity Monitor app
What does the diagnostic reporting feature do?
The diagnostic reporting feature automatically creates a diagnostic report log any time an app crashes
or doesn’t respond. You can view the diagnostic report immediately or view it later in the /Applications/
Utilities/Console app. It’s reported to Apple through the internet.
Which file format is often used for preference files? How can you view the content of this file type?
Most app preferences are property lists, which are XML files that have the .plist filename extension. You
can view the content of these files using Quick Look and edit them using Xcode, which you can get
from the App Store.
Where are app preferences stored?
Application preferences are almost always stored in a user’s Library folder in the ~/Library/Preferences
folder. Newer sandboxed apps must always store their preferences in a ~/Library/Containers/Bundle ID/
Data/Library/Preferences folder, where Bundle ID is the unique bundle identifier for the app.
