Apple Seeds Third Beta of macOS Sierra 10.12.5 to Developers and Public Beta Testers

Apple today seeded the third beta of an upcoming macOS Sierra 10.12.5 update to developers, one week after seeding the second beta and three weeks after releasing macOS Sierra 10.12.4, which introduced Night Shift for the Mac.

The third beta of macOS Sierra 10.12.5 can be downloaded through the Apple Developer Center or through the Software Update mechanism in the Mac App Store.


According to the release notes accompanying the beta, the update "improves the stability, compatibility, and security of your Mac."

Apple's release notes don't often provide a lot of insight into what's included in new beta software, so we don't know what features or bug fixes might be included in the 10.12.5 update.

No notable changes or major bug fixes were discovered in the first two betas, but should anything pop up in the third macOS Sierra 10.12.5 beta, we'll update this post.

Update: Beta 3 is also out for public beta testers.

Quick question: Do these beta updates really need to be front page news?

Unless they reveal something incredible (like a hidden new Mac model) they're not really that newsworthy to the vast majority of people.

Quick answer: Yes.

I like to see it on the front page to inform me that the new betas are available.

Sometimes I see other news articles on the front page that are not relevant to me and I just skip them. I don't then complain about their existence merely because they are not relevant to me.

I appreciate betas being announced on the front page. Is it really so offensive to just skip by it if you aren't interested?

"improves the stability, compatibility, and security of your Mac."

This is so generic, why can't they just say what it fixes? We don't need security info notes but other specific info for the user would be good. Time for a change in language?

I really don't mind, just as long as they don't do something like putting iOS on the front page and pushing MacOS to the Mac Blog.

Well, there are not many news from Apple worthy of anything, so why not to put it on the front page since there is nothing else to talk about.
