An Apple Silicon Mac running macOS 15 or later. Intel Macs are not supported. The app is fully offline, so there is no account to create and nothing to sign in to.
The app runs in Apple's App Sandbox and can only read a card or folder you have granted access to. Click the card in the sidebar and macOS shows its standard panel; approve it once and the app remembers that card. If you skipped the panel, click the card again. You can revoke access at any time in System Settings.
Detect songs makes suggestions. It never decides for you: every stretch long enough
to be a song is listed and numbered, and nothing becomes a clip until you tick it and
press Add. If a row is badged mostly instrumental, that means singing does
not dominate that stretch, not that nobody is singing. Tick it anyway if it is a song.
Detection is tuned on close-miked group singing and is less certain on other material. If it gets a recording wrong, marking clips by hand on the timeline does the same job, and the two can be mixed freely in one take.
macOS could not decode that container, and the app tells you which one and why
rather than hiding it. The usual cause is a file whose extension does not match its real
format, such as a Matroska file named .mp4. Converting it to a standard MP4
or MOV first will let TakeCutter read it.
Please include the TakeCutter version (menu TakeCutter then About TakeCutter), your macOS version, and the camera and recording format involved. If an export failed, the clip length and the quality setting you chose are the two most useful details. Screenshots help.
The app collects nothing and has no network features at all. The full statement is on the privacy page.
