, Apple’s upcoming operating system for Macs.
The current operating system, called Lion, is a great example of how Apple began to merge the PC and tablet.
Mountain Lion further blurs the lines.
So how is Apple doing it? We tok a look at the ways your desktop is getting more tablet-like.
Previously, the custom iOS dictionary lived separately on your iPhone and iPad. With Mountain Lion and iOS 6 the dictionary and your additions can be accessed across multiple devices including your computer.
Documents in the cloud allows you to keep the latest version of your documents on your Mac, iPad, iPhone, and iPod touch. When you edit a document, the changes appear across all your devices.
This is Apple's Google Docs killer. But the ability to pick up where you left off is killer. Imagine playing a game on your iPad, moving to your computer, and then picking up where you left off the heading out the door and playing the same game on you iPhone.
We've always wished we could continue text conversations from our iPhone onto our iPad or MacBook. Now we can with iMessages.
Yes, we know the Messages Beta was already on the Mac and Messages was on the iPad last year but it wasn't seamless.
We couldn't just put our phone down and look at our iPad and see new messages unless someone was texting our Apple ID. Now that we can receive messages from a phone number on all our devices this is possible.
iCloud tabs brings your browsing experience to all devices.
You can see what you were looking at across all devices and instead of saving links you can save entire web pages.
The desktop to mobile transition is seamless.
From your desktop, you will be able to share websites and more with the click of a button. You could already do this on the iPad, but it just takes the extra step out sharing things from your PC.
Instead of copying and pasting, simply click the share button and that article you wanted to tweet is just there.
Now everything on your Mac can be displayed on a computer screen without cords. This was already possible on you iPhone and iPad, but now making it available for the Mac brings the PC into the picture.
Sitting on the couch and surfing using your TV just got so much easier.
Reading List lets you sync web articles between multiple devices. Now we don't have to download an app to pick up reading where we left off. (Think of it as Apple's own version of Instapaper.)
Dictation brings Siri-like commands to the Mac. It's only a matter of time until Siri is available.
Apple did the same thing with Siri for the iPad. The company eased users into the personal assistant with the iPhone, perfected it and then made the service available for the iPad.
The Mac is next.
Apple is really trying to make iCloud the premier cloud service. Mountain Lion and iOS 6 both integrate deeper into the web service.
iCloud now keeps your mail, calendars, contacts, documents, notes, notifications, reminders, and Safari tabs, up to date on every device you use.
Signing in once with your Apple ID automatically sets up iCloud across your Mac.
When you add, delete, or edit something on your Mac, it happens on your iPad, iPhone, and iPod touch. And vice versa.
Now when an app wants to get your attention, you can check your notification centre for important updates.
These updates are nearly identical to iOS, so you'll feel right at home.
Social network services, Twitter and Facebook being integrated into OS X proves just how serious Apple is about mobile.
Being able to tweet or post a status update from anywhere in the system is crucial.
Facebook was already built into iPhoto, but having it throughout the system will make fans much happier. It will be dead simple to share photos, play games, and more through the networks.
