How to uninstall System Data Unpacked on Mac

Before removing System Data Unpacked, save any scan history you want to retain. Its official uninstall documentation identifies ~/Library/Application Support/SysDataMenu as history of measured and deleted paths; this is not the system data that the app scans.

Quit and remove the app

Turn off Launch at login if you enabled it, finish any operation, then quit the menu-bar app. Keep separately installed copies and scripts until you know you no longer use them. The test copied only this main app, not the companion SysDataMenu.app with the same identity.

In Finder’s Go › Go to Folder, copy wanted history before considering removal of ~/Library/Application Support/SysDataMenu. The vendor also names ~/Library/Caches/local.sysdata.menu, ~/Library/HTTPStorages/local.sysdata.menu and ~/Library/Preferences/local.sysdata.menu.plist; review these individually after quitting. After checking the backup, move System Data Unpacked.app from Applications to the Trash. Do not remove the system folders the app measured.

If you installed it with Homebrew

The vendor provides its own tap, distinct from the core cask catalog:

brew uninstall --cask Jarvis322/tap/sysdata

This uninstalls without zap. The tap’s cask manages the main app and has no separate service-removal stanza. Its zap list is the four paths above. Direct brew uninstall --cask --zap Jarvis322/tap/sysdata applies all four independently of Mole’s selections; back up the history first. Mole only uses zap when the complete scope passes its selection and shared-data checks, otherwise selected remnants use its own removal flow.

Check the result

ls -ld "/Applications/System Data Unpacked.app"
ls -ld "$HOME/Library/Application Support/SysDataMenu"
pgrep -ifl 'SysDataMenu'

Printed paths remain; a missing-path error concerns only that path, while a permission error leaves it unknown. With no error, pgrep exit status 1 means no matching command line; a result may be another copy and needs inspection. This does not check every independent script or undo previous cleanup.

What Mole lists

The app is included for removal when selected. The display-name history folder is reviewed and unchecked by default; exact app preferences, caches and HTTP storage are normally selected when present and unprotected. Remove data and settings with apps is off by default; enabling it also selects eligible reviewed data, while shared and protected data retains its boundaries. Retain stores used by another copy.

What this test covered

The copied official main app and selected temporary cache were removed on September 21, 2026. No app-generated Library data was observed at first launch. The companion app, independent script, scan-history recovery and a Homebrew-managed uninstall were not tested.
