Uninstall Mac apps completely, leftovers included

#Why dragging an app to the Trash isn't enough

A Mac app keeps much of its data outside the .app bundle: settings in Preferences, data in Application Support, sandboxed data in Containers and Group Containers, plus caches, logs, cookies and web storage. Some apps also install a launch agent that starts a background process at login, or a privileged helper that runs with system rights.

When you drag the app to the Trash, all of that stays put. Usually it just takes up space. Sometimes it does more: a leftover launch agent can keep trying to start a program that's no longer there, and a fresh reinstall can pick up old, broken settings.

#Where Freshist looks for leftovers

When you uninstall an app, Freshist checks the folders where Mac apps keep their files. In your user Library that includes Application Support, Caches, Preferences (and ByHost), Containers, Group Containers, Saved Application State, Logs, LaunchAgents, WebKit, HTTPStorages, Cookies and Application Scripts, plus plug-in folders such as Audio Plug-Ins, QuickLook, Spotlight, Services and Screen Savers.

It also checks a short list of system folders shared by every account on the Mac: /Library/Application Support, /Library/LaunchAgents, /Library/LaunchDaemons, /Library/PrivilegedHelperTools and the installer receipts in /private/var/db/receipts. The Library folders guide explains what each folder holds.

#How it tells an app's files from everything else

Mac apps have a bundle ID, a reverse-domain name such as com.example.app, and most of their files carry it. Freshist uses that:

• Files whose name matches the app's bundle ID are linked to the app with confidence and can be pre-selected.
• Files that only resemble the app's name are labeled "not sure" and are never pre-selected, so the decision stays with you.
• In the system folders, only items directly inside whose name matches the bundle ID are considered, and they're never pre-selected.

#Review the list, then remove

Before anything is removed you see every related file with its size, and you can untick any of them. Items from your user folder go to the Trash, so an uninstall can be undone until you empty it.

Files in the system folders are owned by macOS (root) and can't go to your Trash. If you select them, Freshist's signed privileged helper deletes them permanently. The helper accepts only items one level inside its short list of folders that match the app's bundle ID, and rejects anything else, even when the request comes from the app itself. Every destructive action is written to a local log at ~/Library/Logs/Freshist/.

#Find the apps you forgot about

Most Macs have a few apps nobody has opened in a long time: a trial from last year, a tool for a single project, an old version of something you've replaced. The Apps tool helps you get that space back, and because it finds each app's related files too, you reclaim the leftovers as well as the app.

#Uninstalling by hand, or with an uninstaller

You can remove an app's leftovers by hand. You'd open each Library folder, search for the app's name and bundle ID, and check every match. Our guide to uninstalling apps on a Mac completely walks through it step by step. It works, but it's slow, and the system folders need an administrator password.

Some software ships with its own uninstaller, and that's the right tool for drivers, VPNs, security software and anything that installs system extensions. Use it first, then let Freshist show you whatever is left. Freshist never removes files that belong to endpoint security or MDM agents, so it won't interfere with tools your IT team manages. The safety page lists the rest of its protection rules.

#One price, lifetime updates

The uninstaller isn't sold on its own. Apps is one of the tools in Freshist, next to Clean, Optimize, Analyze and Status, and they all come with a single license: $9 once, with lifetime updates, on up to 3 Macs. Scanning is always free, so you can compare Freshist's list of leftovers with what you'd find by hand before you buy. There's a 14-day refund if it isn't for you.
