How to uninstall Multica on Mac

Multica is a workspace for handing work to AI coding agents, downloaded from multica.ai. The desktop app runs an agent daemon on your Mac under its own profile, and that profile lives in ~/.multica, a folder the separate multica command-line tool also uses for its default profile. Decide about that folder before you remove the app: keep it if you use the CLI. The CLI and daemon guide also puts agent workspaces in ~/multica_workspaces by default; check that folder for work you want to keep. This guide covers the official Apple silicon download.

Sign out and quit

  1. If you signed in, sign out in the app first. CLI users can run multica auth logout, which the guide says removes the stored token.
  2. Quit Multica from its menu or press Command + Q. The guide says the daemon the desktop app starts belongs to the app and is not registered to start at boot. In the test Multica ran 9 processes, which Mole's Status page groups into one Multica row; check Activity Monitor for multica afterwards.
  3. Open Finder, go to Applications and drag Multica to the Trash.

The app registered no login item or launch agent in the test.

Where the data lives

Press Shift + Command + G in Finder to open each path. Skip any path that is not on your Mac.

Location What it holds What to do
~/.multica Daemon state and profiles. The desktop app's profile is a folder under ~/.multica/profiles; on the test Mac it was one folder named after the server, desktop-api.multica.ai Keep it if you use the multica CLI. Otherwise remove it, or remove only the desktop profile folder. Mole lists ~/.multica for review and does not select it.
~/multica_workspaces The default root for agent workspaces Mole does not list it. Look inside and keep any work you need. The test ran no tasks, so it was not created.
~/Library/Application Support/Multica The Electron data folder: sign-in session, local storage and IndexedDB Remove once you have signed out. Mole lists the folder for review and selects only the cache folders inside it.
~/Library/Application Support/Multica/blob_storage, Cache, Code Cache, DawnGraphiteCache, DawnWebGPUCache, GPUCache Chromium caches Remove. Selected by default.
~/Library/Preferences/ai.multica.desktop.plist Preferences Remove. Selected by default.
~/Library/Application Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/ai.multica.desktop.sfl4 The app's recent-documents list Remove. Selected by default.

Temporary caches for ai.multica.desktop and ai.multica.desktop.helper.GPU sit in your per-user cache folder (getconf DARWIN_USER_CACHE_DIR prints it), and Mole removes them with the app.

Check the result

pgrep -il multica
ls -ld "$HOME/.multica" "$HOME/multica_workspaces" "$HOME/Library/Application Support/Multica"
command -v multica
  • No output from pgrep means no Multica process is running. A printed line is a process that is still alive, possibly a daemon started by the CLI; stop it with multica daemon stop or in Activity Monitor.
  • A path printed by ls still exists. A surviving ~/.multica is expected if you kept it for the CLI. No such file or directory means the path is gone.
  • A path printed by command -v is a separately installed multica CLI. Removing the desktop app does not remove it.

What Mole lists

Mole selects the app, the preferences file, the recent-documents list, the six cache folders inside Multica and the temporary caches. It lists ~/Library/Application Support/Multica and ~/.multica for review without selecting them. It does not list ~/multica_workspaces.

These defaults assume “Remove data and settings with apps” in General › Cleaning is off. With it on, Mole also ticks ~/Library/Application Support/Multica, while ~/.multica stays unticked because the multica CLI can use it too.

What this test covered

On October 20, 2026, the test installed Multica 0.6.3 for Apple silicon from the official download, launched it without signing in, and removed it with a source-built Mole with every review row ticked. Mole moved 11 rows and the app to the Trash. Only ~/.multica was left, holding the desktop profile folder; Mole now lists it, and a build with that rule was checked by putting the app back from the Trash: it listed ~/.multica and moved it. Status showed one Multica row with 9 processes. The app ships an Electron update feed; no update was run. A signed-in account, agent tasks, the multica CLI and Mole's notarized release build were not tested.
