Installation
Info
Built and tested on macOS 26.5+. Provided as-is with no warranty...
Installation is simple... download the file, unzip and then copy it in to your Applications folder. Then just open it. It should register the handler directly.
Warning
The application is not yet signed by Apple which means macOS Gatekeeper will likely complain about it. There are typically two ways to resolve this - either allow the bypass in Privacy and Security, or if you're comfortable with Terminal, use the following command to clear the Quarantine flag: xattr -l /Applications/3MF Viewer.app
Usage
Most use will be via Quick Look - select a .3mf file and hit space. You can rotate and orbit the model directly.
Also has the option to open in a standalone viewer.
