How to Delete Steam from Mac: A Complete Uninstall Guide

Removing Steam from a Mac isn't as straightforward as dragging an app to the Trash. Steam installs supporting files, caches, and game data across multiple locations on your system. If you skip those, you're leaving behind gigabytes of clutter — sometimes without realizing it.

This guide walks through exactly what Steam leaves behind, how to remove it thoroughly, and what decisions you'll need to make based on your own setup.

Why Deleting Steam Requires More Than the Trash

Most Mac apps store everything inside a single .app bundle. Steam doesn't follow that pattern. When you install Steam, it deposits files in several directories:

• The application itself — typically in /Applications/Steam.app
• Application Support folder — stores your game library, Steam client data, and user settings at ~/Library/Application Support/Steam
• Caches — located at ~/Library/Caches/com.valvesoftware.steam
• Logs — stored at ~/Library/Logs/Steam
• Preferences — at ~/Library/Preferences/com.valvesoftware.steam.plist

If you only drag Steam.app to the Trash, the Application Support/Steam folder stays behind — and that folder is often the largest one, frequently exceeding 10–50GB depending on how many games you've installed.

Step-by-Step: How to Fully Uninstall Steam on Mac

Step 1 — Quit Steam Completely

Before deleting anything, make sure Steam isn't running. Click the Steam menu in the menu bar and select Quit Steam, or right-click the Steam icon in the Dock and choose Quit. Deleting files while the app is active can cause errors or incomplete removal.

Step 2 — Delete the Steam Application

Open Finder, navigate to your Applications folder, and drag Steam.app to the Trash. Alternatively, right-click and select Move to Trash.

Step 3 — Remove Steam's Supporting Files

This is the step most users miss. Open Finder, then use the Go menu and select Go to Folder (Shift + Command + G). Navigate to each of the following paths and delete the relevant folders or files:

The tilde (~) represents your home folder. These are user-level locations, so each macOS user account on the machine may have its own copies.

Step 4 — Empty the Trash

Once all files are in the Trash, empty it via Finder > Empty Trash or right-click the Trash icon and select Empty Trash.

🎮 What Happens to Your Games and Save Data

This is where your specific situation matters most.

Steam Cloud saves — If a game supports Steam Cloud sync, your save data is stored on Valve's servers and will still be accessible if you reinstall Steam and log back in. Most modern Steam games support this.

Local saves — Some older games or games without Cloud support store save files locally, often inside the ~/Library/Application Support/Steam folder or within the game's own directory. Deleting the Steam Application Support folder removes those saves permanently.

Game files themselves — All downloaded game data lives inside ~/Library/Application Support/Steam/steamapps. Deleting this folder removes every game you've installed, which is typically the largest portion of the storage Steam occupies.

If you want to keep your games but remove Steam temporarily, you can back up the steamapps folder before deletion and restore it after reinstalling.

Using a Third-Party Uninstaller 🗂️

Some Mac users prefer dedicated uninstaller apps — tools like AppCleaner (free) or CleanMyMac X (paid) can scan for all associated files automatically. These tools identify linked files and folders based on bundle IDs and developer names, reducing the chance of leaving residual files.

The tradeoff is that third-party tools vary in thoroughness and may not catch every Steam-related file, particularly those associated with individual games rather than the Steam client itself. Manual removal gives you more control over exactly what stays and what goes.

macOS Version Differences Worth Knowing

The Library folder is hidden by default on all recent versions of macOS. You access it through the Go menu in Finder while holding the Option key, which reveals the Library option, or by using Go to Folder and typing the path directly.

On Apple Silicon Macs (M1, M2, M3 chips), Steam has historically run through Rosetta 2 translation. This doesn't change where files are stored, but it's worth knowing if you're troubleshooting unexpected behavior before uninstalling.

What Varies Between Users

The right approach depends on factors specific to your situation:

• How many games you have installed affects how much storage you're reclaiming and how careful you need to be about preserving saves
• Whether your games use Steam Cloud determines whether local data deletion is reversible
• Whether you share the Mac with other users means there may be Steam files under multiple user accounts
• Your comfort level with manual file navigation influences whether a third-party tool makes more sense than working through Finder directly

Some users are doing a full permanent removal. Others are clearing space temporarily before a reinstall. Others want to remove the client but keep game data intact. Each of those scenarios involves different choices about which folders to delete and which to preserve — and that part depends entirely on what you actually need from your setup.
