MacSentinel — Find what’s slowing your Mac then clean it safely

MacSentinel is compiled as an Apple Universal 2 binary natively targeting Apple Silicon (M1, M2, M3, M4, Pro, Max, and Ultra) as well as 64-bit Intel Macs running macOS 14 Sonoma or macOS 27 Golden Gate (and later). It requires zero third-party kernel extensions (kexts) and runs entirely in user-space with Mach kernel APIs.

No. MacSentinel is a user-space application that reads telemetry through public Mach kernel APIs. There is no sudo prompt during install, no root daemon, no launchd startup agent, and no third-party kext — which is why it works on locked-down corporate and air-gapped machines.

Unlike traditional Unix tools that average CPU percentages over several seconds, MacSentinel communicates directly with the Darwin Mach kernel scheduler using mach_thread_info() at microsecond cadence. It breaks down execution cycles across high-throughput Performance (P) cores and low-power Efficiency (E) core clusters independently. This differential telemetry allows engineers to detect lock contentions, thread thrashing, and thermal throttling in real time before macOS begins dropping UI fram

Yes. MacSentinel is a Developer ID signed and Apple Notarized app distributed as an Apple Universal 2 binary under the developer account of Appsinfoway. On first launch macOS Gatekeeper shows the standard verified-developer dialog — the same trusted path used by every mainstream Mac utility.
