About:
SystHist is a utility that scans macOS system logs to compile a detailed timeline of all system and security updates installed on the machine. It provides a clear, readable history that helps users and administrators track patch levels and verify compliance. This tool is invaluable for auditing system maintenance and understanding the update history at a glance.

Key Features:

Parses detailed macOS system logs for update events
Generates a clear, chronological list of all installations
Filters specifically for system and security-related updates
Presents data in an easy-to-read format for quick analysis

Use Cases:

Auditing a Mac's update history for security compliance
Diagnosing issues that may have started after a specific system update
Verifying that automatic updates have been applied correctly

Alternatives:

softwareupdate – Apple's built-in command shows pending and recent updates, but SystHist provides a more comprehensive historical log.
Console.app – The native Console app can show log entries, but SystHist automates the filtering and formatting for a much clearer view.
