WhatsApp is developing an updated Mac app that features native Apple silicon support, with the company today providing a TestFlight beta to allow some Mac users to try out the new version of the app.
Apple silicon Macs have been able to use the Electron-based Intel version of WhatsApp for Mac since 2020 thanks to Rosetta 2, but there has been no native version available. An Apple silicon optimized Universal app should run faster and should use less resources on M1, M1 Pro, M1 Max, M1 Ultra, and M2 machines.
