WWDC 2014: What's New in OS X 10.10 Yosemite


On Monday 2nd June 2014, Tim Cook introduced the keynote event to the Worldwide Developer Conference 2014. This year is the 25th anniversary of the conference that started in 1990 with just 1,300 developers who gathered to talk about Apple's System 7. There are now nine million registered Apple developers.

Tim Cook presents WWDC 2014

Cook impressed upon the audience that this keynote was emphasising how OS X and iOS have been engineered to work seamlessly together.  He also said that an entire section of the presentation would be for developers.

Whilst the PC industry declined by five per cent, over the last year, the year-on-year Mac growth was 12 per cent to give a userbase of some 80 million Macs.

User Adoption

Proving a point with statistics

Mavericks, which was announced at WWDC 2013 last June and released last October, is now installed on some 51 per cent of Macs–that's more than 40 million of Apple's computers.  In comparison, Windows 8–which was launched more than two years ago–is only installed on some 14 per cent of personal computers.

To put that into context, it is estimated that there are some 1.5 billion PCs, of which 14 per cent gives 210 million. This means that for every two Macs running OS X Mavericks there are five PCs running Windows 8. 

Windows 8 is still on approximately 17 million more devices than OS X Mavericks

You really can prove any point you want to with statistics, and Apple used their percentages to tell a slightly different story to the actual numbers.

OS X Yosemite: Clarity and Utility

It's a joke-a-minute with Craig "Hair-Force-One" Federighi

Craig Federighi was in his element, joking with the audience, during his presentation for the forthcoming OS X 10.10 which is to be known as Yosemite, following on from the beautiful places in California naming convention established with Mavericks.

OS X Yosemite has new interface, apps and continuity.  The original aqua style of OS X has evolved, through the iterations of OS X, to Yosemite which features a cleaner, flatter and less skeuomorphic interface to bring Apple's desktop operating system more into line with the visual aesthetic of iOS 7.  Federighi puts this as "refining clarity and utility".

Continuing to joke with the crowd, Federighi asks them to "check out the trash can, that is a gorgeously crafted trash can, you won't believe how much time we spent crafting a trash can!", he says in reference to the new style of icons in the dock.

Yosemite Key Features

With Yosemite, you'll notice immediately the translucency to give a sense of depth, concise and clear typography throughout, a new Dark Mode for menus and menu bar so as not to distract and a new look for sidebar apps.

Notification Center adopts the dark translucency, of Yosemite, has a new Today View with calendar information and can be further expanded with reminders, weather and other widgets that can be downloaded from the App Store.  It's not entirely clear yet, but it's a good indication that Dashboard might have been superseded.

Federighi demonstrates Spotlight


Spotlight now presents a large field in the middle of the screen, in a similar way to Alfred app, to find information on the Mac or from the Internet.


Calendar has new looks for week and day views which brings more information about appointments to the fore in a clearly presented way.

iCloud Drive

iCloud Drive is Apple's extension of iCloud that allows you to access OS X and iOS application data through Finder. It also allows you to use iCloud to save other documents to the cloud in a way with which Dropbox users are already familiar.  The functionality has even been extended to Windows PCs.


Mail has a new Yosemite user interface and features faster and more reliable syncing.  A big new feature of Mail is Maildrop which allows the sending of attachments separately from the email.  This allows the sending of attachments up to 5GB in size without the risk of email bouncing back. 

Non-Mac users will receive the email with a link to download the attachment from iCloud.  For Mac users, the process is seamless.


Markup allows the annotation of images or PDFs attached within email.  Circle, draw arrows, add text or sign PDF documents.


AirDrop now works between iOS and OS X.


Safari now features a single bar, at the top, that allows for much more space for the web browser content.  A much cleaner look, the search bar allows you to get at web content and favourites quickly.  

A new tab view gives an at-a-glance bird's eye view of all open pages, together with a stacked view for pages open on individual websites.

Safari continues to innovate in speed and energy efficiency

Safari continues to innovate, in terms of energy efficiency, with the new version being 9.7 times more efficient than Firefox in multi-tab browsing, and 6.5 times faster in javascript processing than Firefox.


Handoff is a new feature where other Apple devices, in proximity, are aware of what each other are doing.  It means that you can work on something on a Mac and then handoff and pick up exactly where you were on an iPad, for example.  This works for iWork products and iMessages.  Start typing a message on an iPhone and finish typing and send it from a Mac, for example.

Instant Hotspot

Instant Hotspot is a new feature for when a Mac does not have an internet connection.  If it sees your iPhone nearby you can select this device for the internet connection and the Mac will set it up without any configuration required on the part of the user. This works even if the iPhone is across the room ...no need to go and get it.


SMS/iMessage–the problem is green bubble friends, who use inferior devices, meaning that their messages only show on one of our Apple devices.  Now, green bubble friends will show across all devices.


Make and Receive Phone Calls, with Mac, to see Caller ID of incoming calls and even accept the call on the Mac and use the Mac as a speakerphone.  This works even if the iPhone is across the room in a charger.  It's even possible to make calls from the Mac, in contacts or from telephone numbers on webpages.


OS X 10.10 Yosemite is immediately available to registered Apple developers and will be available, for download, to the rest of us in the Autumn.  In keeping with the launch of Mavericks, last Autumn, there will be no cost to OS X Yosemite; it will be free of charge.

If you are not a developer but wish to improve OS X Yosemite, you can sign up to the OS X beta program to help feedback to Apple, though this is registered to the first million applicants.
