Sluggish puts a slow-Mac diagnosis in the menu bar
A Mac utility that names a likely cause of sluggish performance and suggests one fix at a time.
- For
- Mac users diagnosing slowdowns, including developers
- Worth noticing
- The developer card appears only when a cause exists and covers lingering Docker, dev-server, Playwright, simulator, and Claude Code processes.
Field notes
The page breaks common causes into actionable cards, including heat-related throttling, browser memory, storage, startup items, and background work from Photos, iCloud, or Spotlight that may stop on its own. Its developer view is described as conditional: it appears only when a cause exists and can group lingering development servers by repository and branch, alongside Docker, Playwright, Xcode, and Claude Code processes. The page also says its optional GitHub pull-request lookup uses the user's own CLI login and remains off by default.
