Launch Riview once after installing, then press Space on a .riv file in Finder. If previews still don't appear, check System Settings → General → Login Items & Extensions → Quick Look and make sure Riview is enabled.
Select any .riv file in Finder, press ⌘I, choose Riview under “Open with”, then click “Change All…”. Riview also offers this on first launch where macOS allows it.
Viewing, Quick Look, the data-binding playground, and image (PNG) export are free with no watermark, forever. Motion exports (video and GIF) start with three watermark-free exports so you can judge the output on your own files; after that, video and GIF exports carry a small corner watermark, and transparent alpha export becomes part of Riview Pro.
A one-time purchase that removes the watermark from video and GIF exports forever and unlocks transparent HEVC alpha export. No subscription — every 1.x update is included. Purchases are handled by Apple through the Mac App Store.
Open Riview → Settings and click “Restore Purchase” while signed in to the same Apple Account that made the purchase. If it still doesn't unlock, email us.
Exports replay the exact live state of the canvas — including your data-binding edits and input values. If a state machine input was changed by the animation itself, restart playback (⌘R) before exporting to capture a clean run.
No — .riv is a runtime format. Riview lets you view, inspect, and export it. Editing happens in the Rive editor, which produces the .riv files Riview plays.
