CST VerdictBased on our analysis of available product data, here is our conclusion:
Forensic investigators and IR teams triaging macOS endpoints will find macMRU-Parser invaluable for fast extraction of user activity timelines from plist files that other parsers leave opaque. The script's 109 GitHub stars and active maintenance reflect real adoption in incident response workflows where manual plist inspection wastes hours. Skip this if your team lacks Python literacy or needs a GUI; this is a command-line tool that assumes operator competence.
Mac incident responders who need to validate forensic integrity during disk imaging should use Disk Arbitrator; it's the only free tool that actively prevents acquisition errors through real-time verification rather than post-hoc validation. The 700 GitHub stars and active maintenance reflect solid adoption among practitioners who can't justify commercial forensic suites for occasional imaging work. Skip this if your team relies on commercial forensic platforms like Cellebrite or EnCase, which bundle imaging with broader evidence analysis; Disk Arbitrator does one job well and stops there.
