About
SystHist is a clean and simple app that lists the full system and security update installation history on your Mac. It tells you all the OS X and macOS system and security updates that have been installed on that Mac.
SystHist probes deep into protected territory to find even silent updates, and gives details of all the files updated.
The current version, SystHist 1.22, is a Universal App for Big Sur, Monterey, Ventura, Sonoma, Sequoia, Tahoe and Golden Gate. The latest update adds support for Golden Gate.
