There are different ways to uninstall unwanted software, depending on how the software is installed on your Mac.

You might want to uninstall software from your Mac for several reasons, such as freeing up storage space if the application is no longer needed or rarely used. Uninstalling can also help improve system performance by reducing background processes that might slow down your Mac. Additionally, removing outdated or incompatible software can prevent potential security vulnerabilities and ensure smoother operation of your system. If you’re troubleshooting an issue, uninstalling and reinstalling a program might resolve errors or glitches. Overall, decluttering your Mac by removing unnecessary software can enhance its efficiency and usability.

What software cannot be uninstalled from macOS?
Certain core system software and applications built into macOS cannot be uninstalled, as they are essential for the operating system’s functionality and stability. These include apps like Finder, Safari, Mail, Messages, Settings (System Preferences), and App Store. Additionally, system utilities such as Terminal, Activity Monitor, and Disk Utility are also protected. These applications are integrated into macOS and are designed to support basic operations, user settings, and overall system management. While some system apps can be hidden or disabled to reduce clutter, macOS safeguards them to prevent accidental removal or system instability.
What are the different methods for installing software on a Mac?
There are several methods for installing software on a Mac, depending on where the application comes from and how it’s packaged. Here are the most common methods:

Mac App Store:
You can browse, download, and install apps directly from the Mac App Store. Apps installed this way are verified by Apple, ensuring they meet security and compatibility standards.

Installer Packages (.pkg files):
Some applications require installation through .pkg files, which guide you through a setup wizard. These are often used for software that needs to install additional components or make system-wide changes.

DMG Files (Disk Image):
Many third-party apps are distributed as .dmg files. You download the file, open it, and drag the app into your Applications folder. After installation, you can eject the disk image and delete the .dmg file.

ZIP Files:
Apps may also be distributed as compressed .zip files. Once downloaded, you unzip the file to reveal the app, which can then be moved to your Applications folder.

Terminal (Command Line):
Advanced users can use the command line to install software, especially for developer tools or open-source software. Package managers like Homebrew are commonly used to streamline installations through the terminal.

Web Installers:
Some applications require downloading a small web installer, which then connects to the internet to download and install the full application.

External Media (USB or Disk):
Software can be installed from external storage, such as a USB drive or DVD, which may contain the installer or the application itself.
Each method offers different levels of convenience and control, depending on the source and type of software being installed.
Does the way a software was installed affect how you uninstall it?
Yes, the method used to install software on a Mac can affect how you uninstall it. Here’s how it varies:
- Apps from the Mac App Store:
These are the easiest to uninstall. Simply drag the app from the Applications folder to the Trash. Alternatively, you can uninstall them directly in Launchpad by clicking and holding the app icon and then selecting the delete (X) button. - DMG-Installed Apps:
If you installed an app via a .dmg file, you can usually uninstall it by dragging the app from the Applications folder to the Trash. However, leftover files (like caches or preferences) may remain in system directories, which you might need to remove manually or with a cleanup tool. - Installer Packages (.pkg):
Apps installed via .pkg files often place files in multiple system directories. To uninstall them, you might need to use the app’s built-in uninstaller (if provided) or download a separate uninstaller from the developer’s website. If no uninstaller is available, manual removal of associated files in system folders like /Library may be required. - Terminal/Command Line Installations:
Software installed through a package manager like Homebrew or directly via Terminal requires command-line instructions to uninstall. For instance, Homebrew uses commands likebrew uninstall <package>
to cleanly remove software. - Web Installers:
Apps installed through web installers often have dedicated uninstallers included in the installation package or available for download from the developer’s website. - Portable or Extracted Apps (e.g., ZIP):
Apps extracted from .zip files or run without a formal installation can be uninstalled by simply deleting the app file. - System and Built-in Apps:
Many built-in macOS apps cannot be uninstalled without disabling system protections like SIP (System Integrity Protection), but doing so is not recommended as it can destabilize the OS.
To ensure complete removal, especially for apps that leave behind residual files, using a third-party uninstaller tool (like AppCleaner) can help simplify the process.
What third party tools exist to uninstall applications on a Mac?
Several third-party tools are available to help you uninstall applications on a Mac completely, including their associated files, preferences, and cache data. Here are some popular options:
- AppCleaner:
A free and lightweight tool that allows you to drag and drop applications to uninstall them. It scans for leftover files and provides a simple way to remove them alongside the app. - AppZapper:
A paid tool with a drag-and-drop interface that identifies and removes applications and their associated files. - TrashMe:
A user-friendly uninstaller that helps you remove apps and clean up associated files. It also includes tools for managing system files and preferences. - Osx Uninstaller:
A paid solution designed specifically for thoroughly uninstalling apps, especially those that may leave behind complex system files. - AppDelete:
A straightforward app removal tool that locates related files and lets you delete them along with the application.
These tools can save time and ensure thorough removal of applications, preventing unnecessary clutter on your Mac. Always download such tools from their official websites to ensure safety and avoid malware.
If I uninstall a software on my Mac will I lose the data I created in it?
Uninstalling software on your Mac does not always mean you’ll lose the data you created with it, but it depends on how the software handles user data. Here’s a breakdown:
- Data Stored Separately:
If the software saves files (e.g., documents, images, or projects) in a specific location on your Mac, such as your Documents folder, Desktop, or an external drive, those files will remain even after uninstalling the app. You can still access them or open them with compatible software. - Data Tied to the App:
Some applications store user data within the app’s installation folder or in hidden system directories (like ~/Library/Application Support). If you manually delete these files during the uninstallation process, you may lose your data. - Cloud-Synced Apps:
For apps synced with the cloud (e.g., Google Drive, Dropbox, or iCloud), your data is typically stored online and can be re-accessed by reinstalling the app or logging in through a web browser. - Backup Settings:
Apps with backup features may have already saved your data externally. For instance, creative apps like Adobe or Microsoft Office often encourage you to save files to their cloud services, ensuring your data isn’t lost during an uninstall.
To avoid losing any important data, consider:
- Backing up your files before uninstalling the app.
- Checking where the app stores its files.
- Avoiding manual deletion of system files unless you’re certain they’re unnecessary.
If you’re unsure, you can reinstall the software later, as many apps retain user data unless explicitly removed.
If I uninstall an app from my Mac will it uninstall it from my other Macs or devices?
No, uninstalling an app from your Mac will not automatically uninstall it from your other Macs or devices. Each device operates independently, so removing an app on one device does not affect its installation on another.
However, there are a few scenarios to consider:
- Apps Installed via Mac App Store:
If you use the same Apple ID across multiple Macs, the app will still remain on other devices even if you uninstall it from one. You’d need to manually uninstall it on each Mac. - Cloud-Synced Apps:
Some apps (e.g., Dropbox, Google Drive) sync their data across devices. Uninstalling the app on one device doesn’t remove it from others, but it may affect synced data if the app is no longer active. - Third-Party Subscription Services:
If the app is part of a subscription, uninstalling it from one device will not cancel your subscription or remove it from other devices. - iOS Devices:
Uninstalling an app on your Mac won’t remove it from your iPhone, iPad, or other Apple devices, as macOS and iOS apps are often managed separately.
If you want to remove an app across all devices, you’ll need to manually uninstall it on each one. For apps with account-based syncing, you may also want to log out of your account to prevent lingering connections.
If I reinstall an app on my Mac will I need to repurchase or relicense it?
In most cases, you won’t need to repurchase or relicense an app when you reinstall it on your Mac, but it depends on how the app was originally purchased or licensed. Here’s a breakdown:
- Apps Purchased from the Mac App Store:
If you bought the app through the Mac App Store using your Apple ID, you can reinstall it for free on the same Mac or any other Mac signed in with the same Apple ID. Simply go to the Purchased section in the App Store and download it again. - Subscription-Based Apps:
For apps that operate on a subscription model (e.g., Microsoft 365, Adobe Creative Cloud), you can reinstall the app without needing to repurchase it as long as your subscription is active. You’ll need to log in with your account credentials to activate the app. - Standalone Licenses Purchased Outside the Mac App Store:
If you purchased the app directly from the developer’s website, you may need the original license key or activation code to relicense the app after reinstalling it. Keep your license information saved in a secure location for this purpose. - Free Apps or Open-Source Software:
Free apps can usually be reinstalled without any additional steps. - Older Software Versions:
If the app is no longer supported or the developer has released a newer version, you may need to purchase or upgrade to the latest version if your previous version is no longer available.
To ensure a smooth reinstallation, always check the app’s licensing terms and keep any purchase receipts, account details, or license keys readily available.
Can I recover an app I accidentally uninstalled?
Yes, you can typically recover an app you accidentally uninstalled from your Mac. Here are the steps you can take, depending on how you acquired the app:
1. Reinstall from the Mac App Store
- If the app was downloaded from the Mac App Store, open the App Store and go to the Purchased section (click on your profile picture in the bottom left).
- Find the app in your purchase history and click the download button to reinstall it.
2. Download from the Developer’s Website
- For apps purchased or downloaded directly from a developer’s website, revisit the site and download the installer again.
- If the app required a license key, make sure you have it available to activate the software after reinstalling.
3. Recover from a Backup
- If you use Time Machine or another backup system, you can restore the app and its associated files:
- Open Time Machine and navigate to the Applications folder.
- Locate the deleted app and restore it.
- This method works best if you recently uninstalled the app and haven’t made significant changes to your backup since then.
4. Check for Cloud-Synced Apps
- If the app is part of a subscription or cloud-based service (e.g., Adobe Creative Cloud, Microsoft 365), you can reinstall it by logging into your account and redownloading the app from the service’s website or app manager.
5. Third-Party App Recovery Tools
- If none of the above methods work, you can try third-party file recovery tools to restore the app. However, this is less reliable and might not work if the app and its files have been overwritten.
To avoid accidental deletions in the future, consider enabling backups or using app management tools to safeguard your applications.
