【Watch Sukeban Deka: The Movie Online】

GoPro kicked off the week with a huge event in Squaw Valley,Watch Sukeban Deka: The Movie Online Calif., to announces its new Hero 5 Black and Hero 5 Black action cameras, and its Karma drone, and they all look suh-weet.

On this week's MashTalk, MashableChief Correspondent Lance Ulanoff, Deputy Tech Editor Damon Beres and I chat about the new GoPro toys, the Yahoo accounts breach and the arrival of macOS Sierra.

On the day of recording, Yahoo confirmed 500 million user accounts were stolen. Sure, we all joked for a second about who still uses Yahoo accounts, but it's no joking matter when the accounts are connected to so many different services.

The bottom line: If you have a Yahoo email account, either shut it down or protect yourself by changing your password or using two-step authentication. We've put together a best practices guide for protecting yourself from hackers.

Anyway, back to Squaw Valley. I was there to check out all the new GoPro gear. Some highlights for the new cameras: touchscreen and GPS for the Hero 5 Black and 4K video recording for the Hero 5 Session.

Both are completely waterproof without any kind of extra case, and both support voice controls. They will also work with GoPro Plus, the company's new cloud subscription service, which lets users auto-upload their footage at home when the cameras are plugged in. The service also lets you access, edit and share footage. The Hero 5 Black costs $399 and the Hero 5 Session $299.

The Karma's foldable design is pretty neat, too, even though it doesn't support object avoidance or auto-follow. It fits in a backpack and comes with a handheld stabilizer grip. The drone costs $799 without any cameras, $999 with a Hero 5 Session and $1,099 with a Hero 5 Black.

We ended this week's MashTalk with Apple's new Mac operating system. MacOS Sierra (RIP OS X) was officially released earlier this week. Lance wrote our review, which you can read here. Lots of new features with Siri and the ability to unlock your Mac with your Apple Watch earning top honors.
