How to Use Quick Look for BMPR files on Mac
If you’re using Balsamiq Wireframes for Desktop on macOS, you may have noticed that Quick Look is available.
Quick Look is one of those features that you don’t realize you’re missing until you try it out. Just select a BMPR file, hit the space bar, and you'll get a preview of your Balsamiq project without having to open Balsamiq Wireframes.
Note: Quick Look is available on macOS 10.15 (and newer).
