iOS 8 is about to be unleash on the world today after debuting earlier this summer at WWDC. Tim Cook is calling it the biggest iOS update ever and for good reason, as the new OS has been packed with hundreds of new tools for developers, as well as new features that make iOS devices, quicker, more productive, and more seamlessly integrated with Mac than ever before.

You won’t see huge visual changes like Apple made with iOS 7 last year, but there’s plenty of features for everyone to be excited about in iOS 8, whether its the new messaging tools, improved camera features, family sharing, Hand-off, or the sleek new Spotlight.

Before you jump headfirst into the biggest iOS release ever, get acquainted with the most important new features in this Cult of Mac guide to iOS 8:

Part two of Tim Cook’s interview with Charlie Rose recently aired on PBS. While not quite as long or revealing as the first part, it’s still definitely worth watching.

Here are six takeaways we got from part two of Cook’s interview:

There may only have been one Steve Jobs, but a recent article from Fast Company draws some interesting parallels between Jobs and Nest CEO, Tony Fadell — previously known as the Apple employee most synonymous with the iPod.

Alongside his obsessive focus on perfection and simplicity, the article notes that Fadell even lives in the same same neighborhood that Jobs once did.

One interesting passage that stands out describes Fadell’s Jobsian approach to management at Nest:

ProCam 2 – confusingly now at v3.0 – is the first camera app that allows manual focus and exposure on devices running iOS 8. You now get full manual control of ISO, shutter speed, focus and white balance, all with neat-o on-screen sliders.

When the iPhone 6 was announced and iOS 8 introduced, so to was unveiled Swift, Apple’s newest app development language.  Swift is the language meant to replace Objective C in iOS app development.

Whether you’re getting a new iPhone or not, chances are you’ll want to upgrade to iOS 8 to take advantage of all it has to offer.

Exciting, isn’t it? A whole new operating system, ready to revolutionize your mobile life.

There are a few things you should do before upgrading to iOS 8, though. First you’ll want to clean up your existing iOS 8-compatible device. Then you need to make a good backup using iTunes, iCloud or a combination of the two. (Bonus: If you do end up getting an iPhone 6 or iPhone 6 Plus, you’ll have a nice, clean, ready-to-rock iOS device to migrate from.)

Here’s how to get your iPhone (or iPad) ready for iOS 8 – the right way.

Apple had to give users a tool to permanently remove U2’s freebie album from their iTunes account, but according to Eddie Cue the album is a colossal hit and has been ‘experienced’ by 33 million iTunes account holders since its release six days ago.

This year’s iTunes Festival lineup is fantastic. It’s got everything, with veterans like Tony Bennett and Robert Plant sharing a festival stage with relative newcomers Sam Smith and Deadmau5.

All those taking the stage at London’s Roundhouse as part of the free shows are consummate performers but — as with any large concert program — there are always some standout acts. We’ve rounded up some of the best moments from the first half of this month-long concert series.

iOS 8’s HealthKit is already starting to change the way health researchers track patients’ wellness even though it hasn’t been released, as two of the country’s top research hospitals have launched HealthKit trials to track diabetics and patients with cancer and chronic disease.

Doctors at Stanford University Hospital say they’ve been working with Apple to track blood sugar levels for children with diabetes, while Reuters reports that Duke University developed a pilot program that uses HealthKit to track fitness measurements for patients with cancer or heart disease.

Apple might have tried to kill read-it-later services by adding Reading List to Safari, but iOS 8’s new Extensibility feature is bringing new life to bookmarking services like Pocket, which said today that its updated app will make it faster than ever to save everything to Pocket.
