Apple today seeded the second beta of an upcoming macOS Sierra 10.12.3 update to public beta testers, one week after seeding the first public beta and one day after seeding the second 10.12.3 beta to developers.

Beta testers who have signed up for Apple's beta testing program will receive the 10.12.3 macOS Sierra beta through the Software Update mechanism in the Mac App Store.

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.

According to Apple's release notes, the 10.12.3 update "improves the stability, compatibility, and security of your Mac." No specific changes, bug fixes, or feature additions were discovered in the first two developer betas.

I wish Apple had a changelog for these. Even if they changed the most minute of things, they still should list it. I don't wanna see that it improves system stability and fixes bugs. I wanna know what bugs it fixes and how it improves system security. It seems like I update my mac every week, and each time it takes like 20 minutes, and comes out the other side completely unchanged. What is the point of a beta program then?

When is it expected to be generally released? I'm hoping it fixes this issue on or before Jan 5. Otherwise, I will have consider returning my machine.

No real expectations. That said, with it being the holiday season, more than likely nothing will happen as far as any final public releases before Jan. 5, and likely some weeks after that.
