Find what slows your Mac.

Blame sits in the menu bar, names what is eating your memory, and ends only what is safe.

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.

Names each cause in one sentence

How long it has run, what it holds, and one button.

Blame's Diagnosis: memory now and after Free, then cards: two hidden browser windows and two scripts left running, each marked safe or asks first.

Shows who holds your memory

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

The memory ring: Google Chrome holds 8.3 GB, and 4,367 MB can come back.

Shows what every AI session holds

Each Claude Code, Cursor or Codex session and everything it started.

Four Claude Code sessions as rings, each with the memory it holds and an End session button.

Autopilot learns, then asks

A rule turns on only after a week under 5% wrong, with your approval.

Autopilot's rules with how often each would have been wrong, against the 5% line.

Shows what changed

Memory spilled to disk fell from 10.9 to 7.3 GB within an hour of quitting Chrome.

Eight days of memory spilled to disk, dropping after Google Chrome was quit.

It ends only what is safe to end.

You see what will end and what stays. Cancel is the default.

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.
