How to uninstall MediaInfo on Mac
Keep any reports you exported from MediaInfo before removing it. MediaInfo reads technical information from media files; the video and audio files you inspected should stay separate from application preferences.
Quit and remove the app
Close MediaInfo, then move MediaInfo.app from Applications to the Trash. Leave inspected media at its existing location. This guide covers the official Mac download; an App Store build or a separate command-line package can have a different installation identity.
Review the local data
In Finder, choose Go › Go to Folder and open each exact path below. Copy anything you need first, then move only the app-owned item you have decided to discard to the Trash. These locations come from the Homebrew removal list or the recorded local check; a missing location needs no cleanup.
| Location | What to keep or remove |
|---|---|
~/Library/Preferences/net.mediaarea.mediainfo.mac-old.plist |
Official-download preferences named by the live cask and observed in the test; the old suffix is part of the real identifier. |
Check the result
These commands only list the app and the locations discussed above. The app filename comes from the cask; adjust it if your official-download bundle has a different name.
ls -ld "/Applications/MediaInfo.app"
ls -ld "$HOME/Library/Preferences/net.mediaarea.mediainfo.mac-old.plist"
An entry printed by ls still exists at that path. No such file or directory means that exact item is absent; Permission denied or Operation not permitted means the check could not establish its state. A retained data folder is expected if you chose to keep it. This check does not search every disk or cloud account.
If you installed it with Homebrew
Uninstall without running zap:
brew uninstall --cask mediainfo
This removes Homebrew's managed app artifacts without applying its zap list. A “not installed” error means Homebrew has no matching cask installation; use the Finder route for a manually copied app.
The live cask source names these additional zap targets:
~/Library/Application Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/net.mediaarea.mediainfo.mac-old.sfl*~/Library/Preferences/net.mediaarea.mediainfo.mac-old.plist~/Library/Saved Application State/net.mediaarea.mediainfo.mac-old.savedState
Some targets can hold settings or personal data. Keep the paths you still need and back them up before considering brew uninstall --cask --zap mediainfo. That direct command applies the cask's entire zap list regardless of Mole's checkboxes. Mole uses zap only when its complete scope passes its selection and shared-data checks; unchecked, shared, out-of-boundary or unsupported targets suppress zap, while selected remnants use Mole's own removal path.
What Mole lists
Mole selects exact bundle preferences such as this mac-old leaf by default. The suffix does not mean you should replace it with a guessed modern identifier. Media files and exported reports are not needed for app removal. These defaults describe the app-data option switched off. Opting into Remove data and settings with apps also selects eligible reviewed app data; shared stores and protected data retain their individual review or protection.
What this test covered
The official universal Mac bundle, selected preferences and temporary cache were removed on 21 September 2026. The tested official bundle used the historical mac-old identifier. No App Store installation or separately installed CLI was removed in that record. Homebrew instructions were checked against the current cask, but this record does not establish a Homebrew-managed uninstall or removal of every possible leftover.
