How to uninstall OpenCat on Mac

Keep wanted conversations and configuration before removing OpenCat. The official FAQ treats OpenCat subscriptions and API services separately from the desktop application; moving the Mac app to the Trash does not cancel those services.

Preserve data and quit

Save wanted conversations and confirm a readable backup before resetting app data. If you rely on another device or a cloud copy, verify that copy separately rather than assuming the desktop app can recover it. Quit OpenCat with Cmd + Q, then move OpenCat.app from Applications to the Trash.

The local test found ~/Library/Application Support/tech.baye.OpenCat and ~/Library/Application Support/OpenCat. After confirming the backup and quitting, open each in Finder with Shift + Command + G and move only the OpenCat folder you chose to discard to the Trash. It also found ~/Library/Group Containers/group.tech.baye.openai; a group identifier needs its ownership checked before removal. Do not remove a shared Group Containers parent or another AI client's files.

Review the remaining app files

The current Homebrew cask also names these exact locations; their presence in the cask does not mean they were all observed in the test. After verifying your backup and quitting OpenCat, open each existing path with Finder Shift + Command + G and move only the OpenCat items you no longer need to the Trash. Skip missing locations and leave the shared CloudKit, com.crashlytics.data and SentryCrash parents alone.

  • ~/Library/Application Support/tech.baye.OpenCat.revenuecat, ~/Library/Containers/tech.baye.OpenCat and ~/Library/Preferences/tech.baye.OpenCat.plist can hold local app state or settings; copy anything wanted before removing them.
  • ~/Library/Caches/CloudKit/tech.baye.OpenCat, ~/Library/Caches/com.crashlytics.data/tech.baye.OpenCat, ~/Library/Caches/SentryCrash/OpenCat, ~/Library/Caches/tech.baye.OpenCat and ~/Library/Caches/tech.baye.OpenCat.revenuecat are the app-specific cache leaves in the cask.
  • ~/Library/HTTPStorages/tech.baye.OpenCat and ~/Library/Saved Application State/tech.baye.OpenCat.savedState are its web-storage and window-state leaves.
  • ~/Library/Application Scripts/group.tech.baye.openai accompanies ~/Library/Group Containers/group.tech.baye.openai. Inspect them individually, keep them while wanted data or another installed app needs them, and remove only a confirmed unshared leaf. Mole keeps separate ownership review for these group rows.

Exact locations in the current cask.

Check the result

pgrep -ifl OpenCat
ls -ld /Applications/OpenCat.app "$HOME/Library/Application Support/tech.baye.OpenCat" "$HOME/Library/Group Containers/group.tech.baye.openai"

Inspect matching executable paths. Missing locations are absent paths; permission errors leave them unverified. A retained data group does not mean the app bundle is still installed. Confirm backups and any account or subscription separately.

If you installed it with Homebrew

brew uninstall --cask opencat

The cask defines its managed removal. Zap names OpenCat support data, bundle-owned container and preferences, app-specific SDK caches, and the group.tech.baye.openai group container and application-scripts leaf. These group locations can contain wanted app data; do not use a full reset without checking ownership and backup.

A direct brew uninstall --cask --zap opencat runs its whole zap list regardless of Mole's checkboxes. Mole checks Homebrew's full removal list and skips --zap when it reaches unchecked data, shared files or anything it cannot verify. It still removes the leftovers you selected.

What Mole lists

Mole selects exact bundle-owned support data, container and preferences when present; these rows can contain wanted data, so back up or uncheck them. ~/Library/Application Support/OpenCat is a review row, unchecked when Remove data and settings with apps in General > Cleaning is off. Turning it on can preselect eligible app data; uncheck this folder to retain it. Group rows keep individual review and a conflicting installed ownership claim blocks their deletion. A cask entry alone does not prove that a group appeared in a particular test.

What this test covered

On September 21, 2026, OpenCat 26.8.0 from the official Mac package was launched without signing in and removed. Selected support data and app-specific SDK cache were removed. The observed data group was not listed in that run, so its deletion was not tested. Conversation recovery, account sync, subscription cancellation and a Homebrew installation were not verified.
