Afterburn
- macOS
Detects heavy CPU load and automatically pauses background processes to maximize performance, then restores everything
Afterburn monitors your CPU and GPU load via Mach kernel APIs and IOKit. When load exceeds your threshold (default 80% for 30+ seconds), it enters Afterburn mode: pausing Time Machine, throttling Spotlight, suspending background apps (SIGSTOP), and reducing system animations. When load drops, everything resumes automatically — paused processes get SIGCONT, Time Machine and Spotlight re-enable, and you get a notification with the session duration. Crashed? Afterburn stores paused PIDs to disk and resumes them on relaunch. Configurable profiles for Compiling, Rendering, or Light optimization.
