GoPro may have inadvertently revealed the company’s first quadcopter earlier this month when a thumbnail for its black-and-white Karma drone began appearing on European websites. We’ve also seen what looks like the new Hero5 camera and user manual along with an unannounced handheld stabilizer. We’ll know for sure how legitimate all these leaks have been, and whether GoPro can upset DJI’s air supremacy when the GoPro press event kicks off at 12 noon ET.

After updating iOS, watchOS, and tvOS last week, Apple will be releasing the latest version of OS X macOS tomorrow. Sierra brings a number of enhancements to the Mac including desktop Siri, tabs in every app, a Universal Clipboard shared between Macs and iOS devices, Auto Unlock for Apple Watch wearers, and enhancements to iCloud, Photos, Messages, and iTunes that bring Macs to parity with the recent changes in iOS. Mostly, Sierra makes living inside of Apple’s ecosystem of devices a lot more seamless in keeping with a trend that began a few years ago. When it'll drop is the mystery. Looking back at the last three releases, the annual Mac OS update hit at 3PM ET in 2013 (Mavericks), 5PM ET in 2014 (Yosemite), and 2PM ET last year for El Capitan. So your guess is as good as mine when Sierra will hit.

The world’s largest camera show

Photoknia is the biennial camera trade show in Cologne, Germany that runs from September 20th to the 25th this year. As the world’s largest camera show, it’s a good chance to check in on where the industry is headed now that smartphones dominate photography on land while drones rule the sky. We’ll have a chance to test all the latest and greatest gear from Nikon, Canon (including the new mirrorless M5), Fujifilm, Sony, Panasonic, Olympus and others all under the same roof. The Verge’s Vlad Savov and Dan Seifert will be on the ground for all the action when the doors officially open on Tuesday.

But that’s just a taste of the week to come. First, let’s get caught up on the weekend that was.
