TapNoiseFind My and a local laptop alarm have different purposes. Find My can help locate and protect a missing Mac when configured and supported. A local alarm makes noise nearby when its triggering conditions occur.
Prepare recovery in advance
Set up Find My for the Mac before it is lost. Check that it appears among your devices and understand the current location and lost-device options for your hardware and account.
Location availability depends on the device and service state. Do not assume a map will always show a live, precise location or that a local alarm provides the same recovery capability.
Understand TapNoise’s role
Guard Mode uses available motion, lid and charger events while TapNoise is running. It has no location service, camera capture or remote tracking.
Force Quit, lid closure or shutdown can stop its protection. It is a deterrent that may draw attention, rather than a mechanism that physically prevents removal or guarantees recovery.
Use sensible layers
Lock your session, keep the laptop under your control and take it with you when possible. A model-compatible physical security accessory may help in an appropriate workspace, but not every MacBook has a built-in lock slot.
For the alarm’s specific behaviour, read Guard Mode limits. For login protection, lock versus sleep is the more relevant setting to review.
