Apple Seeds First iOS 10.2.1 and macOS Sierra 10.12.3 Betas to Public Beta Testers

Apple today seeded the first public betas of both iOS 10.2.1 and macOS Sierra 10.12.3 to public beta testers, one day after seeding the two new releases to developers and two weeks after releasing iOS 10.2 and macOS Sierra 10.12.2.

Beta testers who have signed up for Apple's beta testing program will receive the new iOS 10.2.1 beta update over-the-air after installing the proper certificate on their iOS device, and macOS Sierra 10.12.3 can be installed using 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 are not stable and include many bugs, so they should be installed on a secondary device.

No major outward-facing changes were discovered in the developer betas of macOS Sierra 10.12.3 or iOS 10.2.1, suggesting they are both minor updates that focus on bug fixes and under-the-hood changes rather than major new features.

I just deleted my Beta profile on my iPhone..... It's getting a little tedious to install a new beta every few days.

Starting with the iOS 10 and Sierra betas, bug reporting has been almost impossible. You can write a detailed report and then hit send, then wait for 20 minutes until it says it was unable to send the report and to try again. You then try again and again until it eventually suceeds or you just give up. When it does succeed, you can watch as new betas come and go and not a single one of your reports have been addressed. Perhaps new bugs appear, but the old ones remain (blatant, obvious ones that make you think Apple employees don't use their own software because how can they possibly not see those bugs). The overall effect is bugs accumulate and each beta is worse than the last.

After this happens for each and every piece of feedback you try to send, you start to question if you should even try to report bugs, until you eventually stop sending reports.
feedback app working fine here for me no problem submitting bug reports.

Welcome to Internet life. Remember the days, only time you would update your operating system happened only when you bought a new version?

Is anyone actually noticing an improvement in the final builds since Apple started such a wide and regular public beta testing? I'm certainly not. Makes me think people only download it so they can blog about it or.m show their friends they have it
