Uninstall Orion on Mac

Back up Orion bookmarks, passwords and each profile before removing the browser; profiles hold separate histories and extensions. The September 19, 2026 record covers the app copied from the official DMG.

Quit and remove the app

Quit every Orion profile window and move Orion.app to Trash. Leave ~/Library/Application Support/Orion in place until the saved data is usable. The official page has more product information.

Review the app’s data

The cask lists the Orion profile root, exact cache and preferences, and ShareExtension scripts and container. The IconService cache is another cask entry, but its presence alone does not authorize deleting the profile or extension container.

If you installed it with Homebrew

The Homebrew cask has its own --zap list. brew uninstall --cask orion removes the cask without that list; brew uninstall --cask --zap orion also acts on its listed data without consulting Mole’s checkboxes. Zap includes the profile and ShareExtension container, so it is not equivalent to removing only cache. Mole skips Homebrew zap for browser casks and uses its own selected-remnant path.

brew uninstall --cask orion

Check the result

These commands inspect the running process and one relevant location. They do not remove anything:

pgrep -il "Orion"
ls -ld "$HOME/Library/Application Support/Orion"

No pgrep match means no process with that name is running; a match needs identification before quitting anything. A listed path still exists, while an ls “No such file” error means only that exact path is absent. A permission error is inconclusive.

What Mole lists

Mole leaves the Orion browser profile unselected and selects exact cache and preference rows by default. An embedded ShareExtension needs individual ownership review; a failed Trash move is not a completed removal.

What this test covered

The test used the app copied from the official DMG. On September 19, 2026, the 74 MB Orion profile remained. A 4 KB ShareExtension container could not be trashed, and a 13 MB IconService cache was not collected. The run does not show a clean uninstall of those items.
