How to uninstall Itsycal on Mac
Itsycal reads calendars already configured on the Mac. Before removing it, note any custom menu-bar date pattern and preferences you want to reproduce. If you added a custom hourly sound, copy beep.mp3 from the Itsycal Application Support folder too. Calendar events belong to the configured Calendar accounts, so confirm them there.
The recorded test used the official Mac package; the Homebrew route below is separate.
Remove the app
Open Itsycal from the menu bar and choose Quit; the vendor documents Command-Q as its quit shortcut. Then move Itsycal.app from Applications to Trash. If you enabled launch at login, inspect System Settings › General › Login Items & Extensions for an Itsycal entry after removal. Do not revoke a calendar account or delete calendar files to remove this menu-bar app.
Review local data
The path below is documented in the current Homebrew cask. In Finder, use Go › Go to Folder to inspect it. Do not remove its parent directory or another product’s data.
| Location | Decision |
|---|---|
~/Library/Application Support/com.mowglii.ItsycalApp |
The vendor documents a custom beep.mp3 here. Copy that sound before removing this selected-by-default support folder. |
The tested package uses bundle ID com.mowglii.ItsycalApp. Review only files that actually appear on this Mac. A missing path needs no cleanup.

Check what remains
Run these read-only commands after quitting the app:
pgrep -il 'Itsycal'
ls -d "$HOME/Library/Application Support/com.mowglii.ItsycalApp"
No process output means there is no matching process running now; it does not prove every helper is gone. A listed process needs its owner checked. If ls prints the path, that item remains and needs review. “No such file or directory” means this path is absent; a permission error means its state was not established.
If you installed it with Homebrew
The current itsycal cask has a zap list covering Itsycal HTTP storage and preferences. A direct brew command with --zap applies the cask list without consulting Mole’s checkboxes. After backing up, use this command without --zap:
brew uninstall --cask itsycal
Mole checks each zap path against your selections, other installed apps, and protected locations. An unchecked, shared, or unverifiable path suppresses --zap; selected remnants can still use Mole’s own removal flow. This cask was not the recorded installation channel.
What Mole lists
Mole selects the exact Itsycal bundle-ID support folder, preferences and HTTP storage by default if they exist. Uncheck the support folder until you have copied a custom beep.mp3. Calendar events are not Itsycal remnants. A missing preferences file is not a failed uninstall.
What this test covered
The official ZIP build 0.15.14 was installed and removed on September 20, 2026. It ran as a menu-bar app and produced only an empty bundle-ID support folder in the recorded review. Calendar access was not authorized, so event handling was not tested.
