Show HN: Someone Was Here – Find out who used your Mac while you were away
Many thanks to my ex for inspiring my new MacOS app, Someone Was Here. It takes a photo of whoever uses your Mac while you're away, whether you left it unlocked or they know your password, and sends their photo to your iPhone if the face isn't yours. I built Someone Was Here as a menu bar app making use of Apple Vision and a local face recognition run via Core ML. It all runs locally on your Mac with no tracking or ads. Real-time remote alerts are available via one-time $4.99 lifetime purchase v

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
