You just bought a shiny new Mac, or maybe you’ve had your MacBook Pro for years and the storage bar is looking dangerously red. Either way, you’ve got apps you don’t want anymore. On Windows, you’d go to a control panel and hit a button. On macOS? It feels like you’re just throwing a folder in the trash and hoping for the best.
Honestly, that’s exactly what most people do.
They grab the icon, drag it to the Trash, and think the job is done. It isn't. When you ask how do you uninstall programs on MacBook systems, the answer is actually a bit more nuanced than Apple’s marketing makes it out to be. If you just drag-and-drop, you’re leaving behind "ghost files"—preference panes, cache folders, and supporting files that hide in the deep corners of your Library folder. Over time, this digital lint slows your machine down. It’s annoying.
The Drag-to-Trash Method and Why It’s Only Half the Battle
Most macOS apps are "bundles." This means the .app file you see in your Applications folder is actually a specialized folder containing almost everything the app needs to run. This is why the simple drag-to-trash move works for about 75% of the software out there.
Open your Finder. Go to the Applications folder. Grab that old photo editor you haven't touched since 2022 and drag it to the Trash icon in your Dock. Empty the trash. Done, right?
Not quite.
While the main binary is gone, the "Application Support" files stay behind. These are located in ~/Library/Application Support/. If you’ve ever reinstalled an app and found that it still remembered your login or your custom settings, that’s why. The app was "uninstalled," but its personality stayed in your system's memory. To truly clean things out, you have to go hunting.
Hold down the Option key and click Go in the top menu bar of Finder. This reveals the hidden Library. Inside, you'll find folders like Caches, Preferences, and Logs. If you're serious about freeing up space, you have to manually find the folders named after the app you just deleted and delete those too. It’s tedious. It feels like digital archaeology. But if you're dealing with a massive suite like Adobe Creative Cloud or a heavy game, these leftover files can easily total several gigabytes.

Using Launchpad for App Store Downloads
If you downloaded your software from the official Mac App Store, there is a slightly "cleaner" way to do things that feels a bit more like an iPhone.
- Open Launchpad (that silver icon with the rocket).
- Find the app you want to kill.
- Click and hold the icon until everything starts shaking nervously.
- Hit the small X that appears in the corner.
Apple claims this method is more thorough for App Store apps. Because App Store apps are "sandboxed," the system has a better idea of where all their little tentacles are hidden. When you hit that X, macOS tries to scrub the sandbox clean. Does it get everything? Usually. Is it perfect? No. Some metadata often lingers in the system's container folders, but for the average user, this is the safest path to take.
The "Native Uninstaller" Exception
Then there are the big guys. Microsoft Office, Adobe Creative Suite, and certain high-end audio plugins (like those from Waves or Native Instruments) don't like to be moved. They’re like that one friend who moves into your guest room and brings their own furniture.
If you try to just drag Adobe Photoshop to the trash, you're going to have a bad time. These programs often install "Daemons" or "Agents" that run in the background even when the app is closed. For these, you must use the dedicated uninstaller provided by the developer. Usually, these are found in a subfolder within your Applications folder (e.g., Applications > Adobe Photoshop > Uninstall Adobe Photoshop).
If you ignore this and just delete the icon, those background processes might keep trying to run. They'll search for a "parent" file that no longer exists, causing your CPU usage to spike and your fans to spin like they're trying to achieve takeoff. It’s a mess. Always check the app’s original folder for an uninstaller script first.
Third-Party Cleaners: Are They Worth It?
If you search for how do you uninstall programs on MacBook on any forum, you'll see people screaming about apps like AppCleaner, CleanMyMac X, or Hazel.

Are they scams? Mostly no.
Are they necessary? It depends.
AppCleaner (by Freemacsoft) is a legend in the Mac community because it’s free and lightweight. You open it, drag an app into its window, and it automatically scans your entire Library for every single hidden file associated with that app. It presents you with a list, and you click "Remove." It’s satisfying. It’s what the Trash should have been from the start.
CleanMyMac X is more of a "do-it-all" utility. It’s great for people who don't want to think, but it’s a paid subscription. If you’re a power user, you probably don't need it. If you’re helping your grandmother manage her MacBook Air, it might be a lifesaver.
Then there is Hazel. This isn't an uninstaller per se; it's an automation tool. However, it has a feature where, if you throw an app into the trash, Hazel pops up a notification asking, "Hey, I found some leftover files for this. Want me to bin those too?" It’s seamless.
Clearing Out the "Other" Storage
Sometimes the "program" isn't a program at all—it's a browser extension or a system preference pane.
Go to System Settings (or System Preferences on older Macs). Scroll to the bottom. If you see icons down there for things like Flash Player (RIP), Wacom Tablets, or obscure audio drivers, those are Preference Panes. Right-click them and select "Remove."
For browser extensions in Safari, you have to open Safari, go to Settings > Extensions, and uninstall them there. These little bits of software often eat more RAM than actual standalone apps, especially the ones that "monitor" your browsing to offer coupons or "security."
Dealing with Stubborn Apps and Terminal
Every once in a while, you’ll encounter an app that refuses to die. You try to move it to the Trash, and macOS gives you a smug error message: "This item cannot be moved to the Trash because it's open."
You check. It's not open. You check Activity Monitor. Nothing.
This is when you have to get aggressive. Restarting your Mac usually clears the "hook" the system has on that file. If that fails, you can use the Terminal, though you should be careful here. Typing sudo rm -rf followed by a space and the path to the app will force-delete it. It's the "nuclear option." One wrong character and you could delete your entire documents folder, so maybe stick to the GUI unless you're feeling brave.
Summary of Actionable Steps
Stop just dragging icons to the Trash and expecting a clean slate. Your MacBook deserves better maintenance.

- Audit your apps monthly. Go to the Apple Menu > About This Mac (or System Settings) > General > Storage. Click the (i) next to Applications. Sort by size. You’ll probably find a 10GB game you haven't played since the 2024 elections.
- Use a helper tool. Download a free utility like AppCleaner. It’s tiny, it doesn’t run in the background, and it ensures that when an app leaves, it leaves no traces behind.
- Check your Login Items. Even after an uninstallation, some apps leave "Helpers" in your startup sequence. Go to System Settings > General > Login Items and toggle off anything that shouldn't be there.
- Empty the Trash. This sounds obvious, but macOS doesn't actually free up the disk space until you securely empty that bin. If you’re low on space, that "deleted" 50GB video editor is still taking up room until you click that final button.
Managing a MacBook isn't hard, but it does require a bit more intentionality than most people think. By spending an extra thirty seconds to find those hidden Library files, you'll keep your Mac feeling snappy for years instead of months.
