Stop guessing why your Mac apps close

WhyDidItClose translates termination signals into practical diagnosis so support, QA, and engineering can act quickly.

WhyDidItClose for macOS

Your app closed. WhyDidItClose tells you why in plain English.

WhyDidItClose is a local-first macOS utility that translates termination signals into actionable explanations so support, QA, and engineering can move from guesswork to resolution faster.

What You Get

  • Cause clarity in seconds: distinguish crash, force quit, external kill, and policy/system-initiated termination paths.
  • Actionable guidance: each diagnosis includes a recommended next step instead of raw signal noise.
  • Shareable output: export JSON and CSV when you need to hand off evidence.
  • Confidence transparency: see how sure the diagnosis is before you escalate.

Built for Real Workflows

  • Support teams handling "the app just disappeared" reports.
  • QA teams validating release behavior under failure pressure.
  • Developers triaging flaky close events across environments.
  • Mac power users who need practical answers quickly.

Why Teams Install It

Most tools expose fragments of logs. WhyDidItClose answers the user-facing question directly:

  1. What happened?
  2. Why did it happen?
  3. What should I do next?

Pro Unlock

Core diagnosis stays accessible. Pro unlock adds advanced workflow value:

  • Export and reporting capabilities for team handoff.
  • Faster analysis workflows for recurring incidents.
  • Restore purchases support when reinstalling.
