Note for mac users

macOS

Due to Apple policy, packaging for their platforms is troublesome. You either have to:

Instruct users to ignore scary Gatekeeper warnings by opening Finder > Navigating to the application > Right click > Open > Open. This website generates applications that require this workaround. 

Or pay Apple $100/year for a developer account to sign and notarize the app (very involved process; reach out in feedback for more information)

WKWebView

WKWebView is the preferred way to package for macOS. It will be hundreds of MB smaller than the other macOS-specific environments and typically run the fastest. The app will run natively on both Intel and Apple silicon Macs running macOS 10.13 or later.

Note that:

Video sensing and loudness blocks will only work in macOS 12 or later. Pointer lock will not work. Extremely large projects might not work properly. Use the "Electron macOS Application" (inside Other environments) or "Plain HTML" environments instead if you encounter these issues.
