Returning to a warm MacBook with depleted battery is deeply frustrating—especially when opening Activity Monitor reveals nothing, because the rogue process has already subsided.
macOS Activity Monitor only displays real-time telemetry. To solve this limitation, Dave Plummer, the original author of the Windows Task Manager at Microsoft, engineered TMOG (Task Manager OG) for Mac.
Precision process history and timeline monitor for macOS and Windows. Compatible with Apple Silicon M1 through M4.
Time-Travel Historical Scrubbing
TMOG logs system metrics continuously into an interactive timeline bar. Scrubbing back 15 minutes or 2 hours rewinds the entire process table to that exact timestamp, identifying which app hijacked the CPU.
Automated Memory Leak Tracking
Processes that fail to release allocated RAM are automatically flagged before they exhaust system memory and trigger intensive disk swapping.
Performance vs Efficiency Core Breakdown
Monitor individual Apple Silicon P-cores and E-cores independently to ensure background tasks do not wake high-drain performance cores unnecessarily.
Direct Distribution via Official Site
Because low-level kernel telemetry is restricted by Mac App Store sandboxing, TMOG is officially notarized by Apple and distributed directly through tmog.org.
