- A
System Settings > Desktop & Dock
Why wrong: Desktop & Dock controls dock behavior and desktop appearance, not sidebar folder visibility.
- B
Finder > Preferences > Sidebar
This is exactly where users enable or disable folder visibility in the Finder sidebar.
- C
Terminal command 'defaults write com.apple.finder ShowSidebar -bool true'
Why wrong: While this command exists, it toggles the entire sidebar, not individual folder visibility, and is not the standard user-facing fix.

Spotlight Preferences
Why wrong: Spotlight controls search indexing, not sidebar folder persistence.

How to Keep Documents Folder in Mac Sidebar After Reboot
This 220-1202 practice question tests your understanding of macos features and tools. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user calls the help desk saying that after upgrading to macOS Ventura, the 'Documents' folder in the sidebar keeps disappearing after every reboot. They need it to stay visible. Which macOS feature or tool should you use to fix this?
Quick Answer
The answer is to use Finder > Preferences > Sidebar. This is correct because sidebar visibility for folders like Documents is controlled entirely within Finder’s own preferences, not through System Settings or any other macOS utility. When a user reports that the Documents folder disappears from the sidebar after a reboot, it typically means the checkbox for that folder was accidentally unchecked in Finder’s Sidebar tab, and because Finder preferences are per-user and persist across restarts, re-checking it ensures the folder stays visible. On the CompTIA A+ Core 2 220-1202 exam, this question tests your ability to distinguish between macOS UI customization tools—a common trap is assuming System Settings or Spotlight controls sidebar items, but only Finder Preferences manages that list. A helpful memory tip: think “Finder First”—whenever a folder vanishes from the sidebar, always open Finder’s own preferences before touching system-wide settings.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Finder > Preferences > Sidebar
Option B is correct because the visibility of folders like 'Documents' in the Finder sidebar is controlled directly through Finder's own preferences, not through global system settings. By opening Finder > Preferences > Sidebar, you can check the 'Documents' checkbox, which persists the folder's visibility across reboots. This setting is stored per-user in the Finder plist and is not affected by macOS upgrades.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the global 'Show Sidebar' toggle (which hides the entire sidebar) with the per-item visibility settings in Finder's preferences, leading them to choose the Terminal command or System Settings instead of the correct Finder-specific interface.

Command / output trap
While this command exists, it toggles the entire sidebar, not individual folder visibility, and is not the standard user-facing fix.
Detailed technical explanation
How to think about this question
The Finder sidebar configuration is stored in the user's com.apple.sidebarlists.plist file, which contains arrays for favorites, devices, and tags. When a user checks or unchecks a folder in Finder > Preferences > Sidebar, it modifies this plist, and the Finder reads it at launch to restore the sidebar state. A common real-world scenario is after a macOS upgrade, the plist may be reset if the user's Library folder permissions are incorrect, causing folders to disappear until the preference is re-applied.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
