Yesterday was the day of iOS 9.3 beta 7; today, from the seventh test version of OS X 10.11.4.
The 15E64a build is now available to developers and participants of the Apple Beta Software Program. As with iOS, we’ll hardly see anything new appear on the system, but Apple is still finding edges to trim.
The company has already made it clear that OS X 10.11.4 will be made available in March, bringing news such as Notes protection, the possibility to import files from Evernote and support for Live Photos in the Messaging application; next to OS X, a new version of iTunes also has everything to come out (with possible significant changes).
It is not likely, but if any news appears, we will comment here. 😉
