Apple Seeds Second Public Betas of iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3

by

Apple today seeded the second public betas of upcoming iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3 updates, allowing the public to test the software ahead of when it launches later this month. The public betas come three weeks after the first public betas. Apple has also seeded new public betas of tvOS 18.3 and watchOS 11.3.

Generic iOS 18
Public beta testers can download the updates from the Settings app on each device after opting into the beta through Apple's public beta testing website.

While there are no new Apple Intelligence features for the iPhone or iPad, macOS Sequoia 15.3 brings Genmoji to the Mac for the first time, so Mac users are now able to create custom emoji characters that can be used in place of standard emoji.

In iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3, code suggests that the Home app is set to gain support for robot vacuums, which means Matter and HomeKit vacuums will be able to integrate with Apple's smart home platform in the future.

We are expecting iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3 to be released to the public toward the end of January.

Woah there. Let's not start taking out innocent bystanders in the war against AI already.

You can always do like I did and just not turn it on. That and Siri are off on my iPhone.

I will never understand that.

1) Apple Intelligence is Opt-In and lots of sub-features are also Opt-In (like the Siri-ChatGPT interface)
2) If you opted-in, you can delete apps such as Genmoji if you want
3) Apple Intelligence is still in Beta
4) The AI represents a new era of humanity - of COURSE companies in and out of the Stock Market won't miss that boat and will invest fully into it

If you don't want to install a Beta : I'm 100% with you, if you're not a dev, you don't need it.
But if you don't even want to install the Final release, maybe install it, and just don't Opt-In ? They're going to fix a whole array of bugs, patch security holes, and improve apps such as Safari (WebKit).

Yup, at least we have that ability (on/off) for Apple Intelligence, wish we had it for more “features”

AI?

All I want is a iOS Pro for pro devices. Pro camera, pro Files, pro Calendar, pro interface (granular control).
That might solve some pro-blems.
