Who made this process, and is it safe to quit?
Select any app, process or port and a panel slides in beside the page, pushing it over rather than covering it. It says who made the thing, what it is doing, and what happens if you quit it.

Firefox has used most of your CPU for 8 minutes.
51% of your Mac's CPU, about 3 times its usual. The CPU is at 69°C.
The Inspector, Settings and the full tables need a wider window.
Simulated data, running in your browser.
Trust, in a sentence.
"Signed by Apple." "Signed on this Mac only, so it doesn't say who made it." "Not signed, so nothing says who made it." Then the Team ID, identifier, hardened runtime and sandbox status.
What it is doing.
Ports, children, what started it, the launch agent if there is one, and the full command line with a Copy button.
Its own history.
CPU and memory for this app over the current range, on the same timeline as the rest of the window.
Secrets stay hidden until you ask.
Environment variables can hold API keys, so they sit behind a reveal. The MCP server never returns them at all.
It tells you before you quit.
"Firefox has open windows. Unsaved work in them could be lost." "WindowServer is part of macOS. Other things depend on it, and it would probably start again." Quit always confirms.
