Core features

• Load, unload, and inspect details for kexts installed on the machine, giving you immediate control over individual extensions.
• Verify and repair file ownership and permission settings for kext files to prevent permission-related crashes or failures.
• Keep a running action log that records repairs and other operations, making it easier to trace what was changed and when.
• Help maintain overall system stability and performance by streamlining kext management tasks.

Interface and usability

The app presents a simple, straightforward interface aimed at both casual users and technicians. Primary functions are accessible without complex menus, allowing quick scans and fixes. Typical workflows—like running a permission repair or reloading an extension—can be completed in just a few clicks.

Diagnostics and troubleshooting

A built-in log view documents each action and its outcome, which is valuable when diagnosing persistent driver or extension problems. Reviewing the log can reveal failed operations, permission mismatches, or dependencies that need attention.
