Apple has rolled out updates to watchOS 9.6 and tvOS 16.6, which are now available to the general public.
The build number for watchOS 9.6 is 20U73, replacing the earlier RC build of 20U73, the same number.
And for tvOS 16.6, the new build number is 20M73, which again replaces the previous RC build with an identical build number.
The current releases are mainly focused on improving performance and fixing bugs. This is because Apple is prioritizing the development of its major operating system releases scheduled to launch in the upcoming fall season.
The Apple Watch will generally update on its own within one to two days based on the user's preferences. However, if someone wishes to install the update sooner, they can do it manually.
To manually update, open the Apple Watch app on the iPhone, tap My Watch, select General, then Software Update. If it is available, tap Download and Install.
Your Apple Watch will then update while on charge and within range of the linked iPhone.
