How to uninstall Zettlr on Mac
Zettlr works with Markdown files in your chosen workspace folders. Copy those folders, including linked assets and project settings, before cleanup. The vendor migration guide names config.json, custom.css, user.dic, defaults and snippets inside its Application Support folder as settings worth preserving. Copy only the settings you use; a project export is not a substitute for the source files.
The recorded test used the official Mac package; the Homebrew route below is separate.
Remove the app
Quit Zettlr and move Zettlr.app from Applications to Trash. Keep workspace folders wherever you saved them. Zettlr’s project switch stores project settings; turning that switch off is not an uninstall step and the vendor says it immediately removes those settings.
Review local data
The path below is documented by the vendor. 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/Zettlr |
The vendor migration guide’s macOS settings location. Inspect and copy wanted configuration before removing any matching folder. |
The tested package uses bundle ID com.zettlr.app. 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 'Zettlr'
find "$HOME/Library/Application Support" -maxdepth 1 \( -name Zettlr -o -name zettlr \) -print
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. Each find result is an existing Zettlr-named folder, with its actual spelling. No output means neither spelling was found under this parent; a permission error leaves its state unknown. On a case-insensitive disk, the two spellings may refer to the same folder.
If you installed it with Homebrew
The current zettlr cask has a zap list covering lowercase ~/Library/Application Support/zettlr, logs, preferences and saved state. 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 zettlr
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 lists a Zettlr app-name support folder as a review row, initially unchecked, and selects exact com.zettlr.app preferences by default. The current cask spells its support path lowercase; inspect the actual path before cleanup. It does not collect workspace Markdown files or infer a ~/.config/Zettlr tree from the app name.
What this test covered
The official Zettlr.app 4.8.0 was removed on September 21, 2026, with a 1.9 MB Application Support/Zettlr row selected. This run did not write ~/.config/Zettlr and did not open a real workspace, so document and project settings were not tested.
