Apple today provided public beta testers with macOS 10.12.5, a new update that's been in developer testing since March 28. macOS Sierra 10.12.5 comes a little over a week after releasing macOS Sierra 10.12.4, which introduced Night Shift for the Mac.

Beta testers who have signed up for Apple's beta testing program will receive the 10.12.5 macOS Sierra beta through the Software Update mechanism in the Mac App Store.

macOS 10
Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to both iOS and macOS Sierra betas. Betas should not be installed on a primary machine due to the potential for instability.

The release notes accompanying the developer beta say the update "improves the stability, compatibility, and security of your Mac."

There's not much to glean from Apple's release notes, so it is not clear what minor feature tweaks or bug fixes might be included in 10.12.5. Nothing notable has been discovered in the developer betas thus far.

Is this a joke?
"so.... apple has released something. But we don't know what. But we are still making a news out of it. What is new? No idea, sorry, maybe ask some competent folks around....."

Like seriously has this become a newsfeed for simple events, void of any content, meaning or usefulness?
I'm sitting here half laughing, half not knowing what to feel about this. Maybe it's about time to delete this page from my RSS feed.
Why is it a joke? Apple released something new, that's basically the main piece of the news.

Apple Watch Unlock hasn't worked since I upgraded to 10.12.4 :(
Check in the Settings app under "Security & Privacy" that "Allow your Apple watch to unlock your Mac" hasn't been unchecked when you updated macOS to 10.12.4. If it still is checked, then uncheck it and then check it again. https://support.apple.com/en-us/HT206995
