A user's macOS computer is experiencing slow performance and occasional application freezes. The technician suspects that there might be issues with the permissions of system files or user applications. Which utility is commonly used in macOS to verify and repair disk permissions, which can sometimes resolve these types of issues?
- AActivity Monitor
- BTerminal (using 'fsck')
- CSystem Information
- DDisk Utility
Show answer & explanationAnswer & explanation
Correct answer: D. Disk Utility
Disk Utility in macOS is the primary tool for managing disks and volumes, including verifying and repairing disk permissions. While 'fsck' can check file system consistency, Disk Utility provides a user-friendly interface for permission repair.
Why the other options are wrong
- A. Activity Monitor is used to view and manage running processes and system resource usage, similar to Task Manager in Windows.
- B. Terminal with 'fsck' is a command-line tool for checking and repairing file system consistency, but Disk Utility is the more common and user-friendly GUI option for permissions.
- C. System Information provides detailed hardware and software information about the Mac, but does not repair issues.
