Apple has just released macOS 10.12.2, the latest update to Sierra and one that boasts not only everyone's favorite feature enhancement — new emoji! — but bug fixes, security patches, and performance improvements aplenty.

For some of us, Auto Unlock has been near-magic since launch, quickly logging us into our Macs whenever we bring our Apple Watch close. For others, things haven't been so fast or so smooth. With macOS 10.12.2, Apple has gone over the process from setup to time-of-flight to make sure it starts working and keeps working well for everyone.

Battery Life

Some people have reported that their new MacBooks Pro 2016 haven't been getting the 10 hours of battery life Apple rated them at. While it sounds like Apple is sticking with that 10-hour rating — which is under "normal" usage with the screen mid-bright, no Chrome or similarly resource-hogging apps running, and the embedded Intel graphics being targeted rather than the discreet AMD card on the 15-inch.

What Apple's tweaked is how battery life is displayed. The percentage readout remains, but the time remaining indicator has been removed. It's irksome, but, for now at least, for the best. It's not only almost impossible to accurately predict the time remaining on a system whose load can vary greatly from one minute to the next, the API seemed especially… drunk? lately. Mine would go to 14 hours, back to 7 hours, then to 12 hours, and otherwise being useless for a while now.

Third party app makers I've spoken with have reported similar issues trying to pull the information. So, unless and until it's stone cold accurate, my stress level will do better with it being gone. I just need to learn to judge the percentage on Mac the way I've been doing on iPhone and iPad for years now.

Updated Grab app

Apple's screenshot app, Grab, is being updated to support capturing the Touch Bar, should you have one on your new MacBook Pro. There's a time delay so you can start it, set up the Touch Bar just the way you like it, then have the screenshot saved.

New emoji

The clown face is terrifying. No joke. The rest of the new and newly re-rendered emoji included in macOS 10.12.2 are delightful. They match the new emoji in iOS 10.2 and there's a range of new foods, including bacon (though, sadly, still no poutine!), and a bunch of new professional emoji in both genders. Blogger is a personal fav!
