UninstallPKG for Mac v1.1.8 – Remove and Clean PKG Packages – Chinese Activated Version Download

UninstallPKG for Mac is a professional-grade package uninstaller designed specifically for macOS. It goes beyond the traditional “drag to Trash” uninstallation method, capable of deeply scanning and completely removing applications installed via .pkg installers and all their associated files, including system-level components, drivers, plugins, as well as support files, preferences, and caches scattered throughout the system. Its core value lies in helping users accurately reclaim disk space and maintain a clean, efficient operating system environment.

I. Core Interface and Workspace Detailed Explanation

UninstallPKG’s interface design is simple and intuitive, mainly divided into four functional areas for users to quickly locate and operate. Each area has specific responsibilities and works together to complete complex uninstallation tasks.

1. Top Toolbar: Contains core operation buttons such as “Scan”, “Uninstall Selected”, “Refresh”, and “Preferences”. These buttons are the key entry points for executing the uninstallation process.
2. Left Navigation Sidebar:
   • All Packages: Lists all .pkg installation records detected by the system. This is the default view for browsing all installed packages.
   • Recently Installed: Lists recently installed packages in reverse chronological order, making it easy to quickly locate just-installed applications.
   • Large Size Items: Intelligently filters out packages that occupy large amounts of disk space, facilitating space cleanup. This feature is particularly effective for freeing up hard drive space.
   • Search Box: Located at the top of the sidebar, allows quick filtering of the package list by name. Use keywords to quickly locate targets.
3. Central Main List Area: Displays the specific package list under the category selected in the sidebar. Default displayed columns include:
   • Package Name: The original name of the .pkg file. This name is usually consistent with the official name of the application.
   • Version: The installed version number. Understanding version information helps determine whether an update or uninstallation is needed.
   • Installation Date: The time when the package was installed on the system. This is helpful for tracking recently installed software.
   • Size: The total disk space occupied by all installed files of the package, which is a key reference for cleanup decisions. This value intuitively reflects the space usage of the package.
4. Bottom Information Panel: When a package is selected, this area displays its detailed information, including:
   • File List: A detailed list of all files installed by the package and their paths. This is an important basis for determining file ownership.
   • Dependencies (if any): Indicates whether other packages or applications depend on this item. This information effectively prevents accidental deletion.
   • Operation Log: Displays the results and status of scan and uninstall operations. The log helps users track operation history.

II. Complete Operation Flow: From Scanning to Thorough Uninstallation

Step 1: Launch and Initial Scan

1. Find and click the UninstallPKG icon in the “Applications” folder or Launchpad to launch the software. On first launch, the system may prompt you to confirm permissions.
2. After the software launches, it will automatically perform a quick initial scan of the system, reading all .pkg installation records. This process usually takes only a few seconds, and the scan time depends on the number of packages installed on the system.
3. After the scan is complete, all found packages will be displayed in the “All Packages” list. You can see a complete package inventory.

Step 2: Locate the Target Package

You can find the item you want to uninstall using any of the following methods:

• Browse the List: Select “All Packages” in the left sidebar and scroll through the main list area. Suitable when you know the package name but are unsure of the exact spelling.
• Use Search: Click the search box at the top of the sidebar (or use the shortcut Command + F) and enter keywords for the application name (such as “Adobe Flash”, “Java”, or “Microsoft Office”). The search function supports fuzzy matching.
• Filter by Category: If you want to clean up space, click “Large Size Items” in the sidebar; if you want to uninstall a recently installed failed program, click “Recently Installed”. These smart categories can greatly improve search efficiency.

Step 3: Analyze and Confirm

1. Click to select the target package in the list. The bottom information panel will immediately update to display detailed information about the package.
2. Carefully review the “File List” in the bottom panel: Confirm that these files indeed belong to the application you want to uninstall. You can expand folders to view specific paths and ensure no incorrect selections.
3. Check the “Dependencies” warning: If there is a prompt here, be sure to proceed with caution and confirm that uninstallation will not affect other necessary software. Dependency warnings are an important protection mechanism to prevent system crashes.
4. (Optional) Check the “Size” column to understand the amount of space that can be reclaimed. This helps you evaluate the value of uninstalling the package.

Step 4: Execute Uninstallation

1. Ensure the target package is selected (highlighted).
2. Click the “Uninstall Selected” button in the top toolbar (the icon is usually a trash can), or use the shortcut Command + Delete. This is the standard operation to start the uninstallation process.
3. A final confirmation dialog will pop up, listing again the number of files to be deleted and the total size, and containing a serious warning. Be sure to verify the information in the dialog.
4. If you confirm it is correct, click the “Uninstall” button in the dialog. At this point, UninstallPKG will begin preparing the uninstallation operation.
5. The software will request the administrator password because this operation involves system files. Enter the password and click “OK”. This is macOS’s security mechanism to ensure the operation is legitimate.
6. The uninstallation process begins, and the progress bar will show the status. When complete, the package entry will disappear from the list, and the bottom operation log will show “Uninstallation Successful”.

Step 5: Complete and Verify

• After uninstallation is complete, you can:
  • Go to the application’s installation directory (such as “/Applications”) in Finder to confirm that the main program has disappeared. This is the most direct verification method.
  • Use the shortcut Command + R or select “Action” > “Rescan” from the menu bar to refresh UninstallPKG’s list and ensure the target has been removed. After refreshing, the list will reflect the latest system status.
• You can continue uninstalling other packages or simply quit UninstallPKG. It is recommended to restart your Mac once after completing all uninstallation operations to ensure the system status is fully updated.

III. Advanced Tips for Common Functions

1. Batch Uninstall Multiple Packages

• Hold the Command key and click to multi-select multiple non-contiguous packages in the list. This technique is very useful for cleaning up a group of unrelated software.
• Hold the Shift key and click the first and last items to continuously select all packages within a range. Suitable for uninstalling all software installed during a certain period at once.
• After selecting multiple items, click “Uninstall Selected” to remove them all at once, which is highly efficient. Before batch operations, be sure to confirm that each selected package is one you definitely want to uninstall.

2. Deep Clean “Leftovers”

For applications that have been deleted by dragging but whose .pkg records still remain:

1. Find and select the .pkg record of the software in UninstallPKG. Even if the main program is no longer present, the record will still remain.
2. Check the bottom file list. If most files (especially the main program) are shown as “missing” (possibly indicated by gray or a specific icon), it means the core files have been manually deleted.
3. At this point, executing uninstallation will intelligently delete only the remaining leftover files (such as preferences, caches, etc.), achieving thorough cleanup. This effectively avoids the accumulation of system junk.

3. Use the “Large Size Items” View to Quickly Free Up Space

Regularly check the “Large Size Items” list and sort by occupied space. Prioritize uninstalling large and infrequently used software (such as old games, design suites, virtual machine systems, etc.). This is the most effective way to reclaim tens of GB of disk space. It is recommended to perform such cleanup operations once a month.

4. Export File List for Review

Before uninstalling, if you need to record or review all files installed by a package:

1. Select the package.
2. In the “File List” of the bottom information panel, use Command + A to select all text. Ensure all file names and paths are selected.
3. Use Command + C to copy, then paste into a text editor and save as an uninstallation record. This record can serve as a reference if needed in the future.

IV. Common Issues and Solutions

Issue 1: “The operation could not be completed” is prompted during uninstallation, or there is no response after password verification.

Possible Causes and Solutions:

• System Integrity Protection (SIP) interference: Some core system component .pkg files are protected by SIP and cannot be removed by third-party tools. Do not attempt to uninstall Apple official or macOS system core components.
• Files are in use: Ensure the target application is completely quit (including programs running in the background, which can be checked via “Activity Monitor”). Some background processes may not appear in the Dock.
• Permission issues: Try restarting your Mac, then run UninstallPKG first before performing the uninstallation operation. Restarting can clear temporary permission conflicts.

Issue 2: The application I want to uninstall cannot be found in the list.

Possible Causes and Solutions:

• The application was not installed via .pkg: Many Mac applications are installed by dragging (.app format) or from the Mac App Store. For drag-installed applications, simply move them from the “Applications” folder to the Trash. UninstallPKG mainly handles complex applications installed via .pkg installers.
• Installation records are corrupted or lost: In rare cases, installation records may be abnormal. You can try using “Action” > “Rescan” from the software’s menu bar to refresh the database. If the problem persists, you may need to consider reinstalling the application to rebuild the records.

Issue 3: After uninstallation, some files still seem to be present.

Possible Causes and Solutions:

• User-level file leftovers: UninstallPKG by default focuses on deleting files created during package installation. Some data files generated by applications at runtime in user directories (such as ~/Library/Application Support/) may not be automatically deleted if they are not part of the .pkg installation. You can manually clean these directories.
• Shared by multiple packages: Files shared by other packages still in use will be safely retained. This is normal safe behavior and no need to worry.

Issue 4: What should I do if I accidentally uninstall an important package?

Solution:

• Immediately stop using the computer for other file operations. This prevents new data from overwriting areas that may be recoverable.
