How to uninstall Foxmail on Mac
Foxmail is a sandboxed mail client, so what it keeps on this Mac, including any locally stored mail, sits in its container under ~/Library/Containers. Before removing it, make sure every account you added is syncing normally with its mail server. This covers the official Mac download from foxmail.com, Foxmail.app with the bundle id com.tencent.Foxmail, and the Homebrew cask foxmail, which installs the same download.
Quit and remove the app
- Quit Foxmail from its menu.
- Open Finder's Applications folder, find Foxmail, and move it to the Trash.
Where Foxmail keeps its data
In Finder, press Shift + Command + G and open each location that exists.
| Location | What it holds | What to do |
|---|---|---|
~/Library/Containers/com.tencent.Foxmail |
The app's sandbox; with accounts added, this can include locally stored mail | Selected by default in Mole; confirm your accounts are synced first |
~/Library/Application Scripts/com.tencent.Foxmail |
Scripts folder tied to the sandbox | Selected by default |
Check the result
pgrep -il Foxmail
ls -d ~/Library/Containers/com.tencent.Foxmail
No output from pgrep means Foxmail is not running; a listed process means it is still open, so quit it first. For ls -d, "No such file or directory" means the container is gone. If the path is still printed after Mole removed the app, the move was most likely refused because Mole does not have Full Disk Access, and the uninstall result says so. Grant it in System Settings › Privacy & Security › Full Disk Access and run the removal again, or move the folder to the Trash yourself in Finder.
If you installed it with Homebrew
Mole skips --zap when its list reaches unchecked or shared data, or cannot be fully checked, and still cleans the leftovers you selected.
The foxmail cask's zap list is ~/Library/Application Scripts/com.tencent.Foxmail* and ~/Library/Containers/com.tencent.Foxmail*. Both rows Mole finds there are selected by default, so with nothing unticked Mole can run --zap. The wildcard also reaches any other folder starting with com.tencent.Foxmail. Running brew uninstall --cask --zap foxmail yourself removes the container whatever you ticked in Mole. To keep the container and look through it first, remove only the app:
brew uninstall --cask foxmail
What Mole lists
For Foxmail, Mole selects the app, ~/Library/Containers/com.tencent.Foxmail and ~/Library/Application Scripts/com.tencent.Foxmail by default. Mole does not claim other Tencent apps' app groups, such as WeChat's or WeRead's, on the same Mac. If the container cannot move because Mole lacks Full Disk Access, the result names that.
What this test covered
On September 20, 2026, Foxmail 1.5.8 was copied from the official package into Applications, opened without signing in, and removed with a Mole 1.15 Preview (build 280). The app came off; the 252 KB container failed to move to the Trash with error 513 and stayed on disk. WeChat's and the official WeRead app's groups on the same Mac were not claimed. A signed-in account with local mail and the Homebrew cask were not tested.
