How to Uninstall Yaak on Mac
Yaak keeps API workspaces locally unless you set up directory sync. Export or back up wanted requests, environments and workspace data first; treat API keys in those files as sensitive. The recorded test used a direct download, not a Homebrew installation.
Remove the app and inspect its data
Before quitting, open Export Data from Yaak’s global settings menu, choose the workspaces to include, and save the JSON outside all removal folders; verify it and keep any required encryption keys available privately. Export instructions.
Quit Yaak and move Yaak.app from Applications to Trash. Inspect its exact app support folder before selecting local state; a separate synced directory, if configured, stays at its chosen location. The cask names bundle-ID support, cache, logs and WebKit data. A local workspace database is different from an exported or directory-synced copy. Vendor guidance.
Copy the entire ~/Library/Application Support/app.yaak.desktop folder after quitting for a separate local-state backup. A synced directory is not an independent backup, and encrypted workspace values may require their keys to restore; verify wanted secrets before deleting original state.
After quitting, copy wanted local state from the paths below to an independent private backup outside the removal folders and verify it. In Finder, press Shift + Command + G to open each path or its parent, then move only existing unneeded app-specific items to the Trash. Keep shared parents and other apps' files:
~/Library/Application Support/app.yaak.desktop~/Library/Caches/app.yaak.desktop~/Library/Logs/app.yaak.desktop~/Library/Saved Application State/app.yaak.desktop.savedState~/Library/Webkit/app.yaak.desktop
Check the result
ls -ld ~/Library/'Application Support'/app.yaak.desktop ~/Library/Logs/app.yaak.desktop
Run this read-only check after quitting the app. A printed path still exists; “No such file or directory” means that path is absent, while a permission error needs its own investigation.
If you installed it with Homebrew
The Homebrew cask has a zap list that includes bundle-ID support, cache, logs and WebKit data, not an independently chosen sync directory. Run the command below without --zap if you want to keep those files and inspect them separately. A manual --zap follows the whole cask list regardless of Mole’s checkboxes. Mole skips --zap when its list reaches unchecked or shared data, or a removal scope it cannot verify; selected remnants still follow Mole's own removal flow.
brew uninstall --cask yaak
What Mole lists
Exact bundle-ID application support and cache rows are normally selected. Check the support row before removal if it holds the only copy of a workspace.
What this test covered
Yaak from the official package was removed on September 20, 2026. The bundle-ID rows were removed, but no remote API, populated workspace or directory sync was tested.
