Apple on Tuesday seeded the fifth beta of macOS High Sierra 10.13.3 to developers. The update can be installed by registered developers using the Mac App Store’s update mechanism.

Today’s beta comes a week after beta four. From what we’ve seen in our testing thus far, macOS 10.13.3 is focused more on under-the-hood improvements, rather than new features.

We’re installing beta 5 and we’ll be sure to report back if we see anything of note. And as always, if you see something we’ve missed, let us know about it down in the comments below.
