Yestarday Apple released the tenth beta version of the macOS Big Sur system to developers. It is marked 20A5395G.
The letter G at the end proves that the testing process of this system has not yet come close to the Golden Master version, i.e. the final version (with the letter A in its designation).
In the latest Big Sur beta there are several new features in the user interface. New information has appeared in the power saving menu, which appears when you click on the battery icon, including information about the expected time of full battery charge.
The recognition of switching AirPods headphones between devices has appeared. The speaker icon in the top bar also changes into an icon showing a pair of these headphones when connected to a computer. In the newest, tenth beta, new desktop wallpapers have also appeared.
As usual, we recommend that you backup the data before installing the test version of macOS.
