See what your Mac
is actually doing.
The current build gives your Mac a local view of CPU, memory, energy, disk, network, and process activity. We are actively building out the product—including dedicated AI-worker visibility—and Activity Monitor is a working title that may change.

Everything you need to keep the machine honest.
The current preview covers the core system view. The product is being expanded beyond this surface, and none of the copy below implies the build is finished.
Per-process CPU, load average, and per-core usage so you can spot runaway jobs before the fans do.
RAM, wired, swap, and per-process footprints — find the leak without guessing.
Rough energy score per process so battery hogs show up next to CPU and memory.
Read/write throughput for the system and individual processes when something is thrashing the SSD.
Send/receive rates and connection counts so chatty apps can't hide in the background.
Sortable process table, quick search, and terminate / force-quit without leaving the window.
Try the current preview in a minute.
