At the same time as iOS 10 beta 2 (read: Download and install iOS 10 beta 2 without developer account), Apple has made available the second pre-version of the next major update of its operating system for Mac, macOS Sierra. It is currently only available to developers.
This second macOS Sierra beta arrives two weeks after the first (read: Download & Install macOS Sierra 10.12 beta without a developer account). As a reminder, many new features will be brought by Apple in the final version of the OS, especially in terms of the integration of Siri (read: Keynote WWDC 2016: after OS X, macOS Sierra).
You can now download macOS Sierra beta 2 by going to the Dev Center or from the Updates tab of the Mac App Store if you have installed the first beta. Unsurprisingly, Apple hasn’t shared a changelog regarding the changes made by this second pre-release. If you found them, don’t hesitate to share them in the comments!
