How to uninstall Mark Text on Mac
Save every open Markdown document, then copy the .md files and their referenced images from the folders where you stored them. MarkText’s own installation guide says its Application Support/marktext folder is optional user data; inspect preferences and any unsaved editor state there before removing it. Keep project folders outside that support path.
The recorded test used the official Mac package; the Homebrew route below is separate.
Remove the app
Quit MarkText and move MarkText.app from Applications to Trash, as the project documents. The app’s name is MarkText, while its support folder is lowercase marktext. Do not confuse it with the separate Marked app or delete a shared Markdown folder.
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/marktext |
Official optional user-data location and the 1.9 MB folder removed in the recorded test. Inspect preferences and unsaved state before cleanup. |
The tested package uses bundle ID com.github.marktext.marktext. 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 'Mark Text'
ls -d "$HOME/Library/Application Support/marktext"
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 mark-text cask has a zap list covering marktext support data, 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 mark-text
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 Application Support/marktext as an app-name review row, initially unchecked. Exact com.github.marktext.marktext preferences can be selected by default. It does not treat every Markdown document you edited as a MarkText remnant.
What this test covered
The official MarkText.app 0.19.1 was removed on September 21, 2026, and the 1.9 MB lowercase marktext support folder was selected. No real Markdown project was opened, so the test did not verify document preservation.
