All The New Features In Mac OS X 10.9 'Mavericks'

At WWDC today, Apple announced Mac OS X 10.9, which adds long-awaited features including Finder tabs, tags and multiple display enhancements. Come and check out all the cool new stuff in the next version of the Mac operating system.

Finder Tabs

A long-time feature in alternate file browser Path Finder and plug-in TotalFinder, OS X 10.9 brings tabbed browsing to the OS X Finder. Since OS X 10.5, rumour sites and news outlets have speculated that Apple would add tabs. Now, it finally has.


Apple had added another feature we've seen in everything from web to desktop apps for years. Now you can add tags to documents, folders and other elements in the Finder to easily find what you're looking for without the need to keep all relevant files in a specific folder. Instead, you can browse by tag.

Multiple Display Enhancements

Using multiple monitors with OS X became problematic with the introduction of version 10.7. Now taking an app full screen doesn't force other displays to have a useless grey background. You can put multiple full screen apps on multiple screens. While this feels more like a fix than a feature, OS X 10.9 allows you to use your Apple TV as another display. Not a bad deal if you have a TV but no extra monitor for work.

Battery Life Improvements

We've only seen incremental improvements in battery technology recently, so Apple decided to reduce CPU utilization in OS X 10.9 to improve power usage. One technology called App Nap improves battery life by suspending CPU tasks that you don't need. For example, if you have a CPU-intensive web site running in Safari and you cover it with another window, OS X will suspend that task so it doesn't drain your battery when you're not using it. When you uncover the window, it will resume. Apple added several other technologies behind the scenes that will help developers save battery life through their apps.


OS X 10.9 adds a few new features and technologies to Safari. You'll get your bookmarks in a sidebar for easier access, better JavaScript performance, lower memory usage, and other claimed speed improvements such as smooth and fast scrolling.

iCloud Keychain

Password management solutions such as LastPass and Dashlane save your passwords and sync them amongst your devices. Apple has decided to get in on the act with iCloud Keychain. This will remember passwords for sites Wi-Fi, and credit card numbers. Everything syncs with iCloud, and Apple encrypts all the data to keep it safe. This will be potentially useful, though given iCloud's variable performance and Apple's mixed record in services, proceeding with caution might be wise.

Actionable and synchronised notifications

Now you can get notifications in OS X and actually do something with them. Instead of just clicking them to get to the app, you can reply to a message or answer a video call directly from the notification. You can also update your apps in the background via the Software Update notification as well. iOS notifications will sync with OS X so you don't have to go between devices to see everything.

Calendars, Maps, iBooks

The skeuomorphic design for Calendars, Contacts and other apps which imitated real-world interfaces have been replaced with a much cleaner look. Apple has also added a new Maps application where you can look up directions and send them straight to your iPhone. When you unlock your iPhone, you get sent straight to navigation. Apple also created an iBooks application so you can read your iBooks on your Mac. The feature set seems on par with what you'll find on an iPad.

OS X 10.9 goes out to developers today; everyone else will be able to obtain a copy later this year. Apple hasn't yet specified an upgrade price.


    So for the UI they have basically copied what Windows, Google, Samsung and everyone else has done for some years now. Don't get me wrong, I think it looks good. And welcome to the party Apple. Certainly better than the dated stale UI of OS.X and iOS.

    In addition to tabs, I'm hoping they fixed the rest of Finder so I don't need to bolt-on so many 3rd party apps to fix fundamental omissions in functionality that all other modern OS's have OTB for years now. window-snapping anyone ?

    An iCloud... hope they fixed that world of hurt too. At least there is Dropbox and others that know what they are doing in this space and ably fix the iCloud debarcle.

    Price wise... it wouldn't want to be more than AUD$30 when it arrives IMO.

    The safari claims sound pretty impressive. I like how they have done the demo where they bring iTunes over safari and show the power drop down.

    I like the reading list too ... And the bookmarking

    App nap seems nice too.

    I am going to have to watch the keynote, I don't see anything in there that looks interesting. Definatley nothing that would make me want to pay for the update.

    I have a feeling I'm not going to get this on my C2D 2010 MBP. With all of the changes, I'd be inclined to think they'll leave pre-Core i-series gear behind.

    Looks great, though.

    Why do we have to pay for this? All this would be app updates on every other platform.

      not so happy, No you don't have to pay for this.
