How to Uninstall OmniGraffle on Mac

Check where OmniGraffle diagrams live before removing the editor. A document in iCloud Drive needs its own verified copy; moving it out of a sync root can affect the cloud copy. The recorded test used a direct download, not a Homebrew installation.

Remove the app and inspect its data

Quit OmniGraffle and move its app from Applications to Trash. Leave diagrams and stencils in user folders alone, then inspect app containers individually. The cask zap names both an OmniGraffle container and an iCloud Documents location. An absent path only settles that path; if the iCloud location exists, verify a copy outside the sync root before any cleanup. Vendor guidance.

Check the result

ls -ld ~/Library/Containers/com.omnigroup.OmniGraffle7 ~/Library/'Mobile Documents'/iCloud~com~omnigroup~OmniGraffle

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 OmniGraffle scripts, containers and iCloud locations; a manual zap could remove a cloud document path. 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 uses zap only when its targets are selected, owned and within the checked boundary; otherwise it removes selected remnants through its own flow.

brew uninstall --cask omnigraffle

What Mole lists

Exact app container and script rows are normally selected, while shared or cloud document locations require ownership and protection checks. Do not equate a cask zap list with Mole’s selected targets.

What this test covered

OmniGraffle 7.26 from the official package was removed on September 20, 2026. Quick Look and thumbnail containers remained after Trash permission errors. No iCloud sign-in or diagram restoration was tested.
