Meta does not officially list error 10157. It is an internal OS or browser-level error tied to how your Mac’s network stack communicates with WhatsApp’s servers. This guide will treat it as a connectivity/resource error .

If the browser-based keeps failing with error 10157, bypass the browser entirely. WhatsApp offers a native macOS app.

Use WhatsApp Web for light, occasional messaging. Use the Desktop app for calls, better shortcuts, and native notifications.
