MacBooster for Mac

Make your Mac run faster and smoother

MacBooster from IObit is designed to improve system responsiveness by addressing the common causes of slowdown. It optimizes startup items, repairs disk permission issues, and reduces excessive RAM usage so apps and workflows feel snappier. The app is also useful for machines with limited SSD capacity — by recovering storage, it helps macOS operate with fewer hiccups.

Thorough cleanup to free up space

The app performs a deep sweep of your drive to remove files you no longer need and restore usable storage. It targets a wide variety of clutter so you get more room without hunting through folders manually.

• Locate and remove duplicate files that consume unnecessary disk space
• Reset apps to their default state to reduce accumulated bloat
• Uninstall programs completely, including leftover support files
• Clear dozens of categories of junk (both old and recent caches, logs, and temporary items)

Tools for memory and app management

MacBooster includes utilities to help manage memory and installed software, letting you keep the system lean with minimal effort.

• One-click full uninstalls that remove associated files
• Controls for freeing inactive memory to improve multitasking
• Options to review and disable launch items that slow startup

Real-time security and privacy protection

Beyond maintenance, the software provides active defenses against common online threats. It scans for and removes malware, adware, spyware, and other unwelcome programs that can alter search settings, generate pop-ups, or track activity.

• Blocks and removes detected viruses and spyware in real time
• Finds and neutralizes adware that hijacks browsers or shows unwanted ads
• Helps protect your privacy by removing tracking cookies and risky applications

A comprehensive utility suite with flexible pricing

This utility combines cleanup, optimization, and security features into a single package aimed at keeping macOS systems healthy. A basic version is available at no charge, while a paid tier unlocks more advanced capabilities for users who want deeper or ongoing maintenance.
