Plan a harmless short sequence
Choose the few interface actions needed to show the issue. Avoid recording protected programme content, private messages or another person’s conversation. Write down the steps first so the capture can remain brief. A written error description may be enough if video adds little evidence.
Choose the capture region
Apple documents Shift-Command-5 to open Screenshot, with screen and selected-portion recording controls. Selected-window recording is documented for macOS Tahoe 26 and later. Use the control available on the installed system and check the selected boundary. A window title or address bar can still contain private information even when the rest of the desktop is excluded.
Select the intended sound source
In Options, a microphone records voice or nearby audio. Apple documents Include System Audio for macOS 27 Golden Gate and later. Those are different inputs with different version scope. Do not claim that selecting a microphone is the same as capturing computer audio, or that the current system-audio option exists on every older Mac release.
Record and stop deliberately
Set the save destination and any needed pointer-click indication, then start the short sequence. Apple documents the menu-bar Stop control or Command-Control-Escape to finish. Cancel before recording with Escape if the prepared region is wrong. Keep the stopping method available instead of continuing to capture while searching for it.
Inspect the complete file
Open the saved recording and review picture, sound, beginning and end before sharing. Remove the need for private content by making another safer sample where possible. A recording permission and a successful capture do not establish service entitlement or universal player support; describe only the interface behaviour actually shown.
