Apple's WWDC officially wraps on Friday, but we learned a lot from the opening keynote on Monday.

In 2026, Mashable and the rest of the CNET Group (ZDNET, PCMag, CNET, and Lifehacker) are hosting the Big Guessing Game: Apple Edition to give our readers a chance to predict the biggest Apple news from events like WWDC. Every correct answer earns you one chance to win the new Apple Watch announced in September. (Read the full content rules.) Round one of the game took place in the weeks leading up to WWDC. If you missed your chance to guess, round two will begin July 7, followed by round three before the September iPhone launch event.

In the meantime, we can tell you how many of our readers correctly guessed some of the biggest moments from the WWDC opening keynote. Incredibly, someone even correctly guessed the name of macOS 27 Golden Gate.

Question 1: Will Apple announce a standalone Siri app at WWDC 2026?

Apple finally announced Siri AI, which will be available as a standalone app in the next generation of Apple operating systems. For this warm-up question, 54 percent of Mashable readers said yes, answering correctly.

Question 2: The codename of MacOS 26 is Tahoe. What California landmark, city, or region will Apple choose for macOS 27?

When our tech editor first saw a Volkswagen bug and trippy visuals of California's psychedelic history appear on screen during the WWDC keynote, he wondered out loud if we were about to get macOS 27 Woodstock. Alas, the correct answer was macOS 27 Golden Gate.

One, and only one, Mashable reader correctly predicted macOS's new name. However, there were lots of other good guesses. The most popular wrong guesses were Redwood and Shasta. We also liked Venice, Big Bear, and Napa.

Question 3: WWDC is primarily a software show, but Apple loves a hardware surprise. Which of these devices will get a stage announcement during the keynote?

For this question, readers could guess from four multiple-choice options: Mac Studio M5 Ultra or Max, a redesigned Apple TV device, a foldable iPhone, or none of the above. Unfortunately, there were no hardware reveals at this particular event, and the 23 percent of our readers who guessed "none of the above" earned another entry for the chance to win an Apple Watch.

Question 4: To the nearest minute, how long will the main WWDC 2026 Monday keynote last?

Mashable readers were incredibly accurate in guessing the length of WWDC. The average guess was 75 minutes, and the median guess was 74 minutes. We had people guess 77 minutes as well. Oddly, no one predicted the correct answer to the minute: 76 minutes.

Sorry, folks.

Question 5: In the new watchOS, will ChatGPT be directly available in an app or widget, i.e. not a third-party app or Shortcut?

Mashable readers were pretty evenly split here, with 51 percent guessing in the affirmative and 49 percent in the negative. The pessimists were correct on this one. New watchOS 27 features were barely mentioned during the keynote, but direct ChatGPT access or a dedicated widget are not available.

As a reminder, the next round of Mashable's Big Guessing Game: Apple Edition begins on July 7. Every correct answer will get you another chance at winning the latest Apple Watch released in September.
