OS X Yosemite is the biggest visual overhaul Apple’s made to the Mac in years, but developers at WWDC seemed most excited about one tiny UI tweak – dark mode.

Beta testers eager to try out the the new OS X 10.10 feature were disappointed to find out it didn’t make it into the first Yosemite beta, but our friend Jean-David Gadina, from the DiskAid developers team, has done some digging into the OS X Yosemite beta and discovered a new file not present in Mavericks that can be manipulated to enable the hidden dark mode feature.

Here’s how to do it:

A Twitter account claiming to be run by superstar Apple exec Craig Federighi has been tweeting and retweeting as if it’s run by Hair Force One himself during WWDC. It has amassed more than 14,000 followers in less than two weeks and looks legit at first glance, but don’t be fooled.

We’re pretty sure it’s a fake — and we’ve seen an email that appears to confirm our suspicions.

China is an important market for Apple, and while the company now has deals like the one with China Mobile that help distribute hardware in the country, that is only half the battle. According to new reports, Apple has recently been focusing on wooing Chinese appmakers to get them to develop for iOS.

“Two years ago there was no developer support in China,” Chinese developer Woody Wan told Bloomberg in a recent interview. “There’s been a significant improvement.”

According to the report, Apple has been taking various steps to win over Chinese app developers — including beefing up developer relations by allowing new apps to be approved in the country, opening up a new office in downtown Beijing where the China App Store is located, and building new Chinese-language-specific software to benefit developers. At WWDC this week, Apple held several sessions and social gatherings for programmers visiting from China.

An overwhelming sense of eagerness overtook me after Apple showed off OS X Yosemite at WWDC. The redesigned interface and accompanying features, like a spruced-up Spotlight and the ability to take phone calls on your Mac, made downloading the beta version too intriguing to pass up.

Little did I know that moments after finalizing the installation, I would encounter a massive problem that would send me on an emotional ride.

Apple’s new programming language Swift might be a hit with coders, but bringing it to developers wasn’t quite as speedy a process as its name implies.

Chris Lattner, director of Apple’s Developer Tools department, has updated his personal website with information relating to Swift — including some details of its development. According to Lattner, work on the language began back in July 2010. Lattner implemented much of the basic language structure himself, with only a few other people at Apple knowing of its existence. It was only when several other individuals began contributing to the project in 2011 that it started to gain momentum, leading to it becoming a major focus for the Apple Developer Tools group in July 2013.

At WWDC, Apple debuted its new Family Sharing feature, which allows up to six members of a household to share calendars and even iTunes purchases when using the same credit card — meaning the end of multiple iTunes accounts for different family members.

While Family Sharing allows users to set up their family as a unit able to share photos, calendars, locations, etc. more significant to developers is that it lets users share songs, books, movies, apps, and other purchases.

In a new TV ad for the iPhone 5s, Apple shines a spotlight on some popular fitness trackers. Called “Strength,” the minute-long spot features the old song “Chicken Fat” from President Kennedy’s Physical Fitness Program for schools in the 1960s.

Trackers like the Withings Health Mate, Misfit Shine, and Adidas miCoach Smart Ball are shown in use. Apple just announced its new HealthKit framework for iOS 8 at WWDC, so developers will be able to start feeding Apple’s new Health app data from the kinds of wearables shown in the commercial.

Today a report said that Apple is starting to move its TV ad making in-house. The latest iPad ads featuring the voices of Robin Williams and Bryan Cranston were made internally by Apple, while iPhone spots like the one above are still being made by the ad agency TWBA\Chiat\Day.

If you’ve been holding out for a Retina iMac, the wait may be almost over.

First spotted in the latest Mountain Lion developer beta, code has now been uncovered in OS X Yosemite that references new resolutions for what would be a Retina display-equipped iMac.

Apple and Google aren’t the good friends they used to be thanks to the rise of Android as the iPhone’s main competitor. Ever since Apple axed Google Maps in iOS 6, it has been clear that Google’s days in Apple’s software are numbered.

The hardest Google service for Apple to replace is undoubtedly search. Siri is slowly becoming its own search engine of sorts that draws from multiple services like Wolfram Alpha and Wikipedia, but Google has remained the standard for traditional web search.

In iOS 8 and OS X Yosemite, Google is still set as Safari’s default search engine. But with the introduction of more search partners in Apple’s new software, it’s hard to believe that Google search will enjoy its prominence for much longer.

Apple’s WWDC keynote just days ago brought us many new iOS 8 features to look forward to downloading this Fall. Thanks to an immediate downloadable beta version open for developers, many have found even more useful features and changes not mentioned on Apple’s big stage. In today’s video your host Joshua Smith introduces eight of his top hidden iOS 8 features.
