When will it be, anyone know? I know Rosetta 2 will run it, but some people have reported high battery drain etc because of this. Would be so much better to use whatsapp when its optimized for M1
WhatsApp uses Electron for their "desktop" app (it's basically a web app with its own bundled version of Chromium), so don't get your hopes up, it will still be a slow piece of crap with non-native UI and a huge memory footprint.
