Export to Resolve
The XML is what you pay for. Buy a license, paste the key in License, then export. Polar handles the purchase. Media never leaves this Mac.
Open it the first time
- Open the disk image and drag Latch to Applications.
- If macOS says the developer is unidentified, close that dialog.
- Right-click Latch and choose Open.
This build is ad-hoc signed. Gatekeeper will warn until the app is notarized. That is expected.
Start a project
New projects are saved in Movies/Latch. You do not pick a folder. Use Open project… only if an older project lives somewhere else.
Is this the Latch that unlocks doors?
No. This Latch is multicam audio sync for Mac. It lines cameras to a master recording and exports a Resolve timeline. It is not a smart lock or building-access app.
Do I need a license to try Latch?
No. Download the app and synchronize a real job. You only need a license when you export the Resolve XML.
Where do I paste the key?
In the app: Review & Export → License, or the app menu → License…. Polar emails the key after purchase. It also lives on your Polar purchases page.
Does this run on Intel Macs?
Not this build. It is Apple Silicon only.
Do I need ffmpeg or Python installed?
No. The engine and ffmpeg are inside the app.
Will Latch copy my camera files?
No. It reads them and writes a project file plus local cache. Source media stays where you left it.
