MacBooster

MacBooster is a utility software for macOS developed by IObit. It is designed to optimize system performance, reclaim disk space, and protect user privacy. The software is distributed in a free version with optional paid upgrades (MacBooster Pro) that unlock additional features.

Functionality: MacBooster organizes features into modules such as System Cleaner, which scans for junk files, caches, logs, and language packs; Large & Old Files Finder and Duplicate Finder to identify large, unused files and duplicates; Uninstall Manager to remove applications cleanly; and Startup Manager to control login items. It also includes a Privacy Clean module to erase browser data and application traces, and a Malware Removal module to detect and remove certain threats. Some versions include a File Shredder and Browser Data Cleaning.

Operation and user experience: Scans can be run on-demand with results presented for review and selection of items to delete. The software emphasizes one-click cleanup as a quick option.

Licensing and reception: MacBooster is part of IObit's utility catalog and competes with other Mac cleaning tools. As with other third-party cleaners, users should review items before deletion to avoid removing needed files. The company offers both free and Pro tiers, with Pro providing additional cleaning routines and protections.
