OptiMac cleans, fully uninstalls and monitors your Mac in one 3.2 MB native app for Apple Silicon. A live dashboard shows CPU, memory pressure, disk, network and battery health. The deep clean lists caches, logs and developer leftovers with their sizes, and deletes nothing until you tick it. The uninstaller removes an app along with every file it left behind. It also keeps Homebrew, npm and pip up to date. No account, no telemetry. €20 once, no subscription.
