Proprietary macOS cleaners rely on telemetry, subscription paywalls, and fear-based alert badges while requesting Full Disk Access.

It features a 10-level heuristic app uninstaller, developer cache cleanup (Xcode, Docker, Homebrew), orphan file detection, and safe Trash API recycling. #macOS #PureMac #OpenSource #SwiftUI #CleanMyMac #SysAdmin #DevOps #AppleSilicon #DiskCleanup #SoftwareEngineering
