How to uninstall bilibili (哔哩哔哩) on Mac

The bilibili Mac client, 哔哩哔哩, keeps its local data in an English-named folder, ~/Library/Application Support/bilibili, which held 126 MB in the recorded test. What you save to your bilibili account stays with bilibili, and removing the app does not delete the account or cancel a 大会员 membership. If you cached videos for offline viewing, find where the client saved them before you uninstall; that folder is outside this guide and the test did not cover it. This guide covers the client downloaded from bilibili.com and the Homebrew cask bilibili. 必剪, bilibili's video editor, is a separate app.

Quit and remove the app

  1. Quit 哔哩哔哩 with Command + Q.
  2. Search Activity Monitor for 哔哩哔哩 and bilibili and check that its helper processes have exited.
  3. Move 哔哩哔哩 from Applications to the Trash.

Where the client keeps its data

Press Shift + Command + G in Finder and open each location, skipping any that is missing. bilibili does not document these paths; they come from Homebrew's zap list and the recorded test.

Location What it holds What to do
~/Library/Application Support/bilibili The client's local data Remove it once you are done with the client on this Mac
~/Library/Logs/bilibili Logs Safe to remove
~/Library/Preferences/com.bilibili.bilibiliPC.plist and ~/Library/Saved Application State/com.bilibili.bilibiliPC.savedState Preferences and window state Remove with the app

Check the result

Run these read-only commands after the app is in the Trash:

pgrep -lf 哔哩哔哩.app
ls -d "$HOME/Library/Application Support/bilibili" ~/Library/Logs/bilibili
  • No output from pgrep means the client is not running. A listed process means the app or one of its helpers is still open.
  • ls -d prints each folder that still exists. A surviving Application Support/bilibili is expected if you left it unticked in Mole. "No such file or directory" means that folder is gone.

If you installed it with Homebrew

Mole skips --zap when the zap list reaches data you left unchecked, a path another installed app uses, or anything Mole cannot check, and it still cleans the leftovers you selected.

The bilibili cask's zap list covers ~/Library/Application Support/bilibili, ~/Library/Logs/bilibili, the preferences file, the saved state and the client's recent-items list. brew uninstall --cask --zap bilibili moves them to the Trash. To remove only the app:

brew uninstall --cask bilibili

Homebrew's bilibili cask

What Mole lists

For the client downloaded from bilibili.com:

  • ~/Library/Application Support/bilibili is listed but not selected. Mole added this row after the recorded test, because the English folder name matches neither the Chinese app name nor the bundle ID.
  • ~/Library/Logs/bilibili, also added after the test, and the preferences and saved state under com.bilibili.bilibiliPC are selected by default.
  • Offline video folders are not listed.

What this test covered

On September 20, 2026, 哔哩哔哩 was copied from the official download into Applications, without Homebrew, run, and uninstalled with Mole 1.15 Preview build 280, with every listed item ticked for the test. While running it showed as one row in Status at about 840 MB, and Mole's update check recognized it as an Electron app. The app went to the Trash, but Application Support/bilibili, 126 MB, was not on Mole's list at the time and stayed on disk; the row described above was added as a result. The record includes no signed-in account or cached videos, and the Homebrew cask was not tested.

On September 26, 2026, 哔哩哔哩 was installed again from the official download, opened once, and uninstalled with a development build of Mole with every listed row ticked. Status showed one row of eight processes at about 705 MB. Five items went to the Trash and nothing from the list was left.
