ExpressVPN update allows it to run natively on Apple silicon-based Macs
ExpressVPN rolled out a new update for macOS users. Version 11.5.0 of the app adds native support for Apple silicon Macs, allowing it to "enjoy the full performance benefits of Apple silicon Macs by updating to the latest Mac app." The app developer doesn't specify what benefits it'll bring. Still, it says the app will work "even more seamlessly on the newest Mac computer models, allowing users to enjoy a performance boost along with lower battery consumption."
If you are on an older, Intel-based Apple computer, this app version will still work fine since it is a "universal binary that supports both architectures."
