How to uninstall Plexamp on Mac

Plexamp plays music from your Plex Media Server, so your library, playlists and ratings live on the server and in your Plex account, not in the app. Removing Plexamp from this Mac does not touch them. What the app keeps locally is its own settings and caches. One folder that holds them, ~/Library/Application Support/tv.plex.plexamp, is selected by default in Mole, so untick it if you plan to reinstall and want to keep this Mac's Plexamp settings. This guide covers Plexamp downloaded from plexamp.com and the Homebrew cask plexamp; both install Plexamp.app with the bundle ID tv.plex.plexamp.

Quit Plexamp and remove the app

1. Stop playback and quit Plexamp from its menu.
2. Check Activity Monitor that no Plexamp process is left.
3. Move Plexamp.app from Applications to the Trash.

Removing the app does not cancel Plex Pass or delete your Plex account. Music you downloaded for offline listening is a copy from your server; the test did not download any, so this guide does not say where Plexamp stores it on a Mac.

Where Plexamp keeps its data

Plex's help pages do not document Plexamp's Mac locations; the table lists what the test observed and what the Homebrew zap list names.

Check the result

After the app is in the Trash, run these read-only commands:

pgrep -lf Plexamp.app
ls -d "$HOME/Library/Application Support/tv.plex.plexamp" "$HOME/Library/Caches/tv.plex.plexamp"

• No output from pgrep means Plexamp is not running. A listed process means it is still open.
• ls -d prints each folder that still exists and reports "No such file or directory" for the rest. After a Mole uninstall with the default selection both should be gone; if you unticked the Application Support folder to keep your settings, that one stays.

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 plexamp cask's zap list covers ~/Library/Application Support/Plexamp, ~/Library/Application Support/Caches/plexamp-updater, ~/Library/Caches/Plexamp, every ~/Library/Caches/tv.plex.plexamp* folder, ~/Library/Logs/Plexamp, the preferences file and saved state. Running brew uninstall --cask --zap plexamp yourself moves them to the Trash, whatever you ticked in Mole. The list does not include ~/Library/Application Support/tv.plex.plexamp or ~/Library/WebKit/tv.plex.plexamp, the two folders the tested version actually wrote its data to, so a zap leaves them behind; remove them by hand if you want them gone. To remove only the app:

brew uninstall --cask plexamp

Homebrew's plexamp cask

What Mole lists

For Plexamp downloaded from plexamp.com:

• ~/Library/Application Support/tv.plex.plexamp is selected by default, because it is named after the app's bundle ID. Untick it to keep your settings.
• ~/Library/Caches/tv.plex.plexamp, ~/Library/Caches/Plexamp, ~/Library/Logs/Plexamp, ~/Library/WebKit/tv.plex.plexamp and the temporary caches for tv.plex.plexamp and its WebKit processes are selected by default.
• Your music library is on your server and is never listed.

What this test covered

On September 26, 2026, Plexamp 4.50.19 for Apple silicon was downloaded from Plex's Plexamp download, installed, launched once without signing in, and uninstalled with a development build of Mole with every listed row ticked. While it ran, Mole's Status page showed Plexamp as one row of eight processes, about 189 MB, including the macOS WebKit processes it started. The app and all 10 listed rows went to the Trash and a rescan found none of them left; three empty WebKit folders in macOS's per-user temporary folder, which were never on the list, stayed. No login item or background task appeared. An earlier test on September 21, 2026 with version 4.50.17 from the official download removed the same kinds of folders, while three WebKit temporary folders could not be moved there. Nothing was signed in or downloaded.
