Free during the beta. For macOS 26, notarized by Apple.
Every slowdown, named.
What holds your memory, why, and whether it is safe to end.

Each app on a ring, and what comes back if you quit.

Questions
Didn’t find your answer? Write to the founder.
Will it end something I need?
Only what passes the safety check ends. Databases are never ended from a button, a child doing protected work protects its whole tree, and every fix shows its list before you confirm.
Does Autopilot act on its own?
Not unless you switch it on. It suggests, and you choose Do it or Not this; Do it can be undone for 10 minutes.
Activity Monitor is free. Why this?
Activity Monitor lists every process and its memory. It does not say which session left a program running, whether it is safe to end, or what slows your Mac right now. Blame names the cause and ends the whole tree after checking it is still the same program.
Does anything leave my Mac?
Not unless you switch on anonymous usage counts in Settings: one report a day of counts only, never a program name, a path or a command. Logs stay on your Mac for 14 days and are never sent.
How heavy is it?
About 31 MB of memory and 1% CPU, measured on the 0.2.3 release build over 43 hours, 1–3 Oct 2026.
Why not the Mac App Store?
Its sandbox forbids signalling other processes, so Blame could not end anything. It is a direct download, signed with a Developer ID and notarized by Apple.
