How to Delete Steam on Mac: A Complete Uninstall Guide

Removing Steam from a Mac isn't as simple as dragging the app to the Trash. Steam scatters files across multiple locations on your system, and if you only delete the main application, those leftover files continue taking up space. Understanding where everything lives — and what happens to your game library — makes the process much smoother.

Why Deleting Steam on Mac Requires More Than One Step

On macOS, most apps store more than just their core application file. Steam is particularly thorough about spreading its files around your system. Beyond the Steam.app file in your Applications folder, it writes data to your Library folder, including caches, logs, preferences, and your actual downloaded games.

If you only drag Steam to the Trash, you'll still have gigabytes of game data, saved configurations, and cached files sitting on your drive. For users trying to free up significant disk space, or those troubleshooting a corrupted installation, a full removal means tracking down all of these locations.

What Gets Stored Where

Before deleting anything, it helps to understand what Steam leaves behind and where:

The game library folder inside Application Support/Steam is usually the largest by far — potentially tens or hundreds of gigabytes depending on what you've installed. Deleting the entire Steam folder there removes all locally downloaded games.

How to Fully Uninstall Steam on Mac 🗑️

Step 1: Quit Steam Completely

Before removing any files, make sure Steam isn't running. Click the Steam menu in the top menu bar and select Quit Steam. You can also right-click the Steam icon in the Dock and choose Quit. Force-quitting via Activity Monitor is an option if the app is unresponsive.

Step 2: Delete the Main Application

Open your Applications folder (via Finder or using Cmd + Shift + A), locate Steam.app, and drag it to the Trash, or right-click and select Move to Trash.

Step 3: Remove Remaining Steam Files

This is the step most guides skip, and it's where the bulk of the storage reclaim happens.

Open Finder, click the Go menu in the top menu bar, and select Go to Folder. Type ~/Library and press Enter. From there, navigate into each of these folders and delete Steam-related items:

• Application Support/Steam — This contains your entire game library and Steam data. Deleting this folder removes all downloaded games.
• Caches/com.valvesoftware.steam — Cached data Steam accumulated over time.
• Preferences/com.valvesoftware.steam.plist — Your stored preferences file.
• Logs/Steam — Log files from past sessions.

Drag each of these to the Trash.

Step 4: Empty the Trash

Once everything is moved to the Trash, empty it to actually free the disk space. Right-click the Trash icon in the Dock and select Empty Trash.

What Happens to Your Game Library and Progress

This is where individual situations start to diverge significantly. Steam Cloud saves — available for many (but not all) games — store your progress on Valve's servers. If a game supports Steam Cloud, your save data survives uninstalling Steam entirely. When you reinstall Steam and re-download the game, your progress returns automatically.

Games that don't support Steam Cloud store saves locally, often inside that Application Support/Steam folder you just deleted. If preserving save data matters to you, check whether each game uses Steam Cloud before proceeding. You can verify this in Steam by right-clicking a game, selecting Properties, and looking at the Steam Cloud section — though that requires Steam to still be installed.

Using Third-Party Uninstallers

Some Mac users prefer dedicated uninstaller apps — tools that scan for all associated files and present them in a single interface before deletion. These can be useful for catching files that manual methods might miss, and they reduce the chance of leaving orphaned data behind.

That said, the manual method described above covers the primary locations Steam uses. Whether a third-party tool adds meaningful value depends on how thorough you want to be and how comfortable you are navigating the Library folder manually.

Reinstalling Steam Later

If you're uninstalling Steam to troubleshoot an issue rather than permanently leaving the platform, a clean reinstall — fully removing all files before reinstalling — often resolves problems that a simple reinstall over an existing installation wouldn't fix. Corrupted cache files or preference conflicts are common culprits for Steam behaving unexpectedly on Mac.

Reinstalling is straightforward: download the installer from steampowered.com, run it, and log back in. Your account, purchased games, and any Cloud-saved progress remain tied to your Steam account regardless of what happens on your local machine.

macOS Version Differences Worth Knowing 🍎

The process above applies broadly across recent versions of macOS, but there are a few things worth noting. macOS Catalina and later dropped support for 32-bit apps, which affected some older Steam games. If you're on an Apple Silicon Mac (M1, M2, M3 chips), Steam runs natively, but some older games may still require Rosetta 2 translation. These factors don't affect the uninstall process itself, but they're relevant if you're removing Steam partly because of game compatibility issues.

The Library folder is hidden by default in recent macOS versions — using the Go to Folder method (Cmd + Shift + G in Finder, or via the Go menu) is the most reliable way to access it without adjusting system settings.

How complete your uninstall needs to be — and whether game saves or a future reinstall factor into your decision — depends entirely on your own situation and what you're trying to accomplish.
