How to uninstall Sequel Ace on Mac

Sequel Ace is a sandboxed app, so its saved connections (favorites) and preferences live inside its container, ~/Library/Containers/com.sequel-ace.sequel-ace. Mole selects that container by default, so copy your favorites out first if you want them after a reinstall. This guide covers the build downloaded from Sequel Ace's GitHub releases, the channel this test used. The Homebrew cask sequel-ace and the Mac App Store version use the same bundle ID and container.

Quit Sequel Ace and remove the app

1. Close your open connections and quit Sequel Ace from its menu or with Command + Q.
2. To keep your favorites, copy ~/Library/Containers/com.sequel-ace.sequel-ace/Data/Library/Application Support/Sequel Ace/Data/Favorites.plist somewhere outside ~/Library. Sequel Ace's own guide names this file as where favorites live, and its preferences file sits in the same container at Data/Library/Preferences/com.sequel-ace.sequel-ace.plist. Migrating from Sequel Pro
3. Drag Sequel Ace from Applications to the Trash, or run brew uninstall --cask sequel-ace if you installed it with Homebrew.

Where Sequel Ace keeps its files

Check the result

pgrep -il "sequel ace"
ls -d ~/Library/Containers/com.sequel-ace.sequel-ace "$HOME/Library/Group Containers/NKQ4HJ66PX.sequel-ace"

• No output from pgrep means Sequel Ace has quit.
• ls -d prints each folder that still exists and reports "No such file or directory" for the rest. A surviving container means your favorites are still on disk, either because you unticked it or because the move failed; see below. A surviving group folder is expected after a Mole removal, because Mole does not list it.

If you installed it with Homebrew

The sequel-ace cask's zap list reaches the container, both Application Scripts folders and ~/Library/Group Containers/NKQ4HJ66PX.sequel-ace. Running brew uninstall --cask --zap sequel-ace yourself moves all of them to the Trash, favorites included, whatever you ticked in Mole. Homebrew Sequel Ace cask

When Mole removes a Homebrew install, it checks the zap list first. Mole does not accept the NKQ4HJ66PX.sequel-ace group folder as Sequel Ace's own, so while that folder exists Mole leaves --zap out: Homebrew removes the app and its receipt, and only the rows you ticked go to the Trash.

What Mole lists

For Sequel Ace installed from GitHub, the Homebrew cask or the Mac App Store:

• ~/Library/Containers/com.sequel-ace.sequel-ace and ~/Library/Application Scripts/com.sequel-ace.sequel-ace are selected by default. The container holds your favorites.
• Mole can also list ~/Library/Application Scripts/NKQ4HJ66PX.sequel-ace, taken from Homebrew's zap list for this app, but does not select it.
• ~/Library/Group Containers/NKQ4HJ66PX.sequel-ace is not listed. Group containers are protected in Mole unless the folder name carries the app's own bundle ID or a group ID Mole can tie to it, and this one is only the Team ID and a short name.
• Moving another app's container to the Trash needs Full Disk Access. If Mole reports it could not move the container, turn on Full Disk Access for Mole in System Settings › Privacy & Security and run the removal again.

What this test covered

Sequel Ace was copied from its official GitHub release into Applications and uninstalled on September 19, 2026, with Mole Preview 277, alongside other apps in the same batch; there was no Homebrew receipt. The container was selected by default, but moving it to the Trash failed with a Trash permission error; the batch's other failures were temporary cache folders. The NKQ4HJ66PX.sequel-ace group folder was not listed. The Mac App Store and Homebrew versions, and saved favorites or SSH connections, were not tested.
