Apple OS X Yosemite Preview

Yosemite is Apple's next big release of their desktop operating system due out later this year. Once again, as a free upgrade for existing Mac owners. 

Apple has better integrated its desktop OS with their iPhone and iPad iOS 7 devices. While the look of the desktop matches the iOS 7 interface design with translucency, brighter, flatter styling, new icons and fonts mercifully they've not had a Windows 8 moment; it's still a traditional desktop with drop down menus and a dock.

Phone You can make and receive phone calls on your Mac. When your iPhone rings, the caller's name, number and picture show as a notification on your Mac. You can answer calls by clicking the notification and your Mac becomes a speakerphone. You can make phone calls using Contacts, Calendar, Messages and Safari.

No WiFi? Your Mac automatically uses the personal hotspot on your iPhone which appears in the Mac's WiFi menu.

Messages All the SMS and MMS messages that you receive on your iPhone now appear in Messages regardless of what type of phone your friends and colleagues are using. You can respond using whichever device is the most convenient.

iCloud Drive You can store any file in your iCloud Drive and then find it on any device. The iCloud Drive is available in the Finder window and works like any other folder on your Mac, just drag and drop your files into the folder. You can rearrange everything as you wish and see all your files organised in the same way on your iPhone and iPad.

Mail Drop You can send large attachments without having to worry whether they will get through or not. Send large files like videos, images and presentations and they are automatically uploaded to iCloud. Mail Drop works with any email service, if your recipient uses Apple Mail then they receive the attachment as they normally do, otherwise they receive a link to download the file.

AirDrop Sharing files is so easy with AirDrop, you can take a file from any folder and send it to a nearby Mac or iOS device and vice versa. Send a document to a colleague in the next room or send a presentation to a customer across the table. Easy.

Handoff You can automatically pass whatever you're doing from one device to another whenever they are in range. Start writing an email on your iPhone and then finish typing it on your Mac using a full keyboard without losing your place. Or start writing a report on your Mac and finish it off on your iPad on the train home. Handoff works with the following apps: Mail, Pages, Numbers, Keynote, Maps, Messages, Reminders, Calendar, Contacts and Safari.
