How to uninstall Lapce on Mac

Save open files and back up your Lapce configuration and installed editor data before removing the Mac app. The cask names both a home-directory store and Library support folders, which can differ between installations.

Quit and remove the app

Quit Lapce and move Lapce.app from Applications to the Trash. Use the Homebrew route if it created the lapce command link; keep project repositories and language tools that you installed separately.

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.

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/Lapce.app"
ls -ld "$HOME/Library/Application Support/dev.lapce.Lapce-Stable"
ls -ld "$HOME/.lapce"
ls -ld "$HOME/Library/Application Support/Lapce"

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 lapce

This removes Homebrew's managed app artifacts without applying its zap list. The ordinary uninstall stanza also asks the app to quit. Homebrew also removes its managed command links or wrapper; a separately installed command-line package is independent. 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:

• ~/.lapce
• ~/Library/Application Support/dev.lapce.Lapce-Stable
• ~/Library/Application Support/Lapce
• ~/Library/Saved Application State/io.lapce.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 lapce. 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 lists app-attributed support and cask data rows for review, not selected by default. The exact support folder written by the tested stable app is the important spelling to inspect, rather than a guessed lowercase identifier folder. Matching caches are selected by default. 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 app, selected stable support folder and temporary cache were removed on 21 September 2026. The test did not create ~/.lapce; it does not establish removal of a populated alternate home store, personal project or external language server. Homebrew instructions were checked against the current cask, but this record does not establish a Homebrew-managed uninstall or removal of every possible leftover.
