Notice

The current Windows installer is unsigned, and the macOS app is not notarized. Your operating system may display a security warning the first time you open it.

If macOS prevents IMGo from opening, move IMGo.app to the Applications folder, open Terminal, and run:

xattr -cr "/Applications/IMGo.app"

Then open IMGo again.
