App Cleaner & Uninstaller Pro for Mac v8.4.2 – Software Uninstaller Chinese Activated Version Download

I. Core Features Overview

App Cleaner & Uninstaller Pro is a professional-grade software uninstaller and system cleaner designed specifically for macOS. Its main function is to thoroughly remove applications and all their associated files and folders, effectively freeing up disk space and maintaining system stability. In addition, the software can deeply scan and clean useless files, redundant language packs, system caches, and more, comprehensively improving Mac performance.

In the macOS ecosystem, many users habitually drag application icons to the Trash when uninstalling software. This seemingly simple approach actually leaves behind a large number of residual files. These “digital junk” files accumulate over time, slowing down system response and taking up valuable storage space. App Cleaner & Uninstaller Pro was created to solve this pain point. It acts like a meticulous housekeeper, helping you wipe away every “footprint” of each application.

According to a review report from the well-known tech media MacWorld, Macs that have not cleaned up system residual files for a long time may experience a 15% to 20% decrease in running speed. Using a professional uninstaller can effectively avoid this situation. App Cleaner & Uninstaller Pro stands out among similar software with its deep scanning algorithm, making it a capable assistant for maintaining Mac health.

II. Detailed Main Features

1. Thoroughly Uninstall Applications

The traditional drag-to-Trash method cannot completely delete residual service files of applications. This tool can:

• Deep Scan: Detect and clean trace files left behind from previously deleted applications.
• Complete Removal: Ensure that applications and all their service files are deleted together, leaving no residue.

For example, when you uninstall Adobe series software, manual deletion often leaves a large number of cache and configuration files in the “Library” folder. App Cleaner & Uninstaller Pro precisely locates these “escaped fish” and removes them with one click, restoring your Mac to a clean state.

2. Manage System Startup Items

Too many startup programs slow down system boot speed and overall performance. With this feature, you can:

1. View and manage all login items.
2. Disable unnecessary startup agents and system daemons.
3. Completely disable or delete items that affect startup speed.

Many users find that their Mac boots slower and slower, often because there are too many background startup items. For example, WeChat, Tencent Meeting, Thunder, and other software are set to launch at startup by default. In the “Startup Items” module of App Cleaner & Uninstaller Pro, you can see all startup programs at a glance and easily disable unnecessary ones, bringing boot speed back to its peak.

3. Manage System Extensions and Plugins

Provides centralized management of system-level extensions, including:

• Disable or uninstall user and kernel extensions.
• Delete macOS installation residual files.
• Clean browser extensions and screen savers.
• Manage preference panes and internet plugins.
• Uninstall Dashboard widgets.

Although browser extensions are convenient, too many or malicious extensions can severely slow down web page loading speed and even leak privacy. With this tool, you can easily manage those extensions hidden deep in the system, just like cleaning up your desktop, ensuring system security and stability.

4. Clean Residual Files

Specialized scanning and cleaning of remaining files from deleted applications and corrupted service files, thoroughly freeing up disk space. This feature is very practical for users who frequently install and uninstall software, helping you recover “hidden” storage space.

5. Manage File Associations

Easily modify the default opening program for specific file types in macOS, and intuitively manage the association between files and applications. For example, when you don’t want to use the system’s built-in Preview to open images but want to use Photoshop by default, this feature comes in handy.

III. Version 8.4.2 Changelog
