About:
KextViewr is a macOS utility that provides a comprehensive list of all kernel extensions currently loaded on the system. It presents this technical information in a clear, filterable, and user-friendly interface, making it easy to inspect the low-level software running on your Mac. This tool is invaluable for security analysis, troubleshooting system instability, or simply satisfying curiosity about your machine's inner workings.

Key Features:

Lists all currently loaded kernel extensions (kexts)
Displays detailed information like bundle identifier, version, and path
Simple, clean, and intuitive user interface
Helps identify potentially outdated or malicious kexts

Use Cases:

Security auditing to check for suspicious or unsigned kernel extensions
Troubleshooting system crashes or hardware compatibility issues
Gathering detailed system information for technical support

Alternatives:

kextstat – A command-line tool that provides similar raw data, but lacks the graphical, filterable interface of KextViewr.
EtreCheck – A more comprehensive diagnostic tool that includes kext information among many other system checks.
