Apple today seeded the first beta of an upcoming macOS Sierra 10.12.3 update to developers, just one day after releasing macOS Sierra 10.12.2 and almost three months after launching the macOS Sierra operating system.
macOS Sierra 10.12.3 is available for download through the Apple Developer Center or through the software update mechanism in the Mac App Store.
Because this is a first beta, we don't yet know what features are included in the update, but Apple's release notes say the 10.12.3 update "improves the stability, compatibility, and security of your Mac." We'll update this post with any changes that are discovered in the beta.
Available since September, macOS Sierra is the latest Mac operating system. It includes Siri support, Apple Pay for the web, Universal Clipboard, Apple Watch auto unlocking, improved iCloud Drive integration, Picture-in-Picture multitasking, and dozens of smaller features that can be found in our macOS Sierra roundup.

Apple has made a change to its development process for iOS 28, macOS 28, and corresponding software updates, according to Bloomberg's Mark Gurman.
In his Power On newsletter today, he said Apple separates development of each year's new operating systems into three major stages. Typically, he said each stage consists of four weeks of coding followed by a four-week "convergence" period where...
Don't they already measure disk space in units of 1000 instead of 1024 to show a 1TB drive as 1TB?
O/T: nope, it's official 1000 gigabytes (GB) = 1 terabyte (TB) but 1024 gibibyte (GiB) = 1 tibibyte (TiB) (unless you adhere to the JDEC standards but every time you use "giga-" to refer to a multiple of 1024 a pedant has an anxiety attack).

Maybe Apple should consider introducing the new unit of time "ihour" - 30% shorter than the standard "hour" - for its battery life estimates?
Expecting to see the removal of "used space" indicators in the Finder. Apple knows that If the Finder doesn't tell us that we only have 1 gig of space left, then we'll never run out of room.
