macOS Sierra HERO

macOS Sierra (version 10.12) is the name of Apple’s desktop operating system, and was revealed at its annual Worldwide Developers Conference on June 13, 2016.

After using the “OS X” moniker for the twelve previous versions of the OS, Apple, as long expected, adopted the familiar naming convention that’s present for all of its other platforms, such as iOS and watchOS.

macOS Sierra includes some notable enhancements over the incumbent, OS X El Capitan. Features such as Siri, Apple Pay support for the web, Auto Unlock, Picture in Picture, and Universal Clipboard headline the update.

Users can expect additional new features as well, as has been outlined in our post covering many of the new additions to macOS.

macOS Sierra is currently available as a developer beta, with a public beta expected soon, and a public release scheduled for this fall. Once released, the update will be available free of charge from the Mac App Store, just like past versions of OS X.

Broken macOS Mojave or High Sierra Installer? Expired certificate will require a fresh download

Longtime macOS users will know that even though the Mac has a built-in recovery partition, it’s always useful to have a dedicated USB drive with a macOS installer. I am a big fan of using a tool like DiskMaker X to create them to keep around if I need to wipe a drive and reinstall macOS quickly. If you have a drive created for Mojave, Sierra, and High Sierra, know that a certificate has expired. If you are getting an error similar to “This copy of the Install macOS Mojave.app application is damaged, and can’t be used to install macOS”, read on to learn how to fix it.

Back in September, a major bug with PDF-handling that led to Fujitsu temporarily warning ScanSnap owners to cease using their scanners with Sierra. The problem was later identified as a bug in the PDFKit framework in macOS 10.12.

Take Control of Preview co-author Adam Engst (via Daring Fireball), says that although Apple applied fixes in 10.12.1, it has reintroduced bugs in 10.12.2 – to the extent that he now advises against using Preview for PDF editing at all for now …

macbook-pro-time-remaining

Following a flurry of media coverage highlighting battery life complaints for Apple’s 2016 MacBook Pros, we’ve learned an internal investigation by the company has determined there isn’t a hardware flaw to address with the new machines. Instead, Apple is today removing inaccurate “time remaining” battery life estimates from macOS, a move that it hopes will address concerns among users.

There has been a lot of confusion over battery life estimates on the new 2016 MacBook Pros. Some were reporting estimates lower than expected via the macOS battery life status menu which offered an on the fly prediction of remaining juice, but there was a clear misunderstanding about how the feature worked. 

Apple didn’t have a ton of public information about how the battery life estimations were calculated, but we’ve talked to those in the know to get the scoop on why they’ve decided to remove it entirely following the MacBook Pro battery life concerns.

How-To: Dock Picture-in-Picture videos anywhere on macOS Sierra [Video]

By default, Picture-in-Picture videos on macOS Sierra are docked in one of the four corners of your Mac’s display. If you try to move the window elsewhere, it will quickly snap back to one of the four default corners. This is very similar to how Picture-in-Picture mode works on the iPad.

But it’s also possible to dock videos anywhere on your display by using a handy keyboard combination. Watch our brief hands-on video for the quick how-to.
