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.

Apple will introduce at least five new devices at its iPhone-centric event next month, and it's also possible we'll get devices waiting on Siri AI like the Apple TV.

For the first time since Apple started selling standard and "Pro" iPhones, we're not going to get an entry-level iPhone model this fall. Apple doesn't plan to release an iPhone 18 in September, and will only launch the iPhone 18 Pro, iPhone 18 Pro Max, and foldable iPhone Ultra. The lower-cost iPhone 18 won't come out until spring 2027.

Apple has yet to reveal when the iPhone 18 Pro and iPhone Ultra will be announced and released, but the dates usually follow a familiar pattern.
As usual, the event is expected to take place in the first half of September.
Labor Day falls on September 7 this year. The last time the holiday was on that day was in 2020, but the iPhone event that year was delayed until October due to the...
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.
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
Apple's first foldable iPhone, with a book-style design featuring a ~5.5-inch outer display and a ~7.8-inch inner display with a minimal crease down the middle.
