OS X 10.8 Mountain Lion Stalks iOS

Starting 16 February 2012, Apple has made available a developer preview of OS X 10.8 Mountain Lion, announcing plans to release the new operating system version this summer (or winter, for our friends in the Southern hemisphere), and dropping the word “Mac” from the name in the process.

This upgrade from 10.7 Lion to 10.8 Mountain Lion isn’t meant to be a major overhaul like the one we saw moving from 10.6 Snow Leopard to 10.7 Lion. The core user experience remains largely the same, with a series of enhancements that build on the changes made in Lion. Since Mountain Lion is only in pre-release you shouldn’t take this article as a review. Not all of the features were enabled on the demonstration system provided to me by Apple, and much is likely to change before it’s released to the public.

Living in the iCloud -- Mountain Lion unifies the experience between iOS and the Mac while still maintaining those differences that are important to each platform. Notably, iCloud becomes the glue of the Apple ecosystem, playing a stronger role than we’ve seen before. For example, the first time you set up a user account, Mountain Lion prompts you for iCloud credentials and loads all your information and even Mac App Store purchases (unless you use a different Apple ID for iCloud and the Mac App Store). In a nice return to the days of MobileMe, you can even synchronize your Mail, Contacts, and Calendar accounts if they have been configured on another Mountain Lion-using Mac connected to your iCloud account. (Oh, and iCal and Address Book have been renamed to match iOS, so they’re now Calendars and Contacts.)

iCloud’s Documents in the Cloud service gains several enhancements. For example, in a demo by Apple, I saw that as you edit a document on an iOS device, the updates are pushed immediately to a Mac version of the document even if it’s open in the Mac application. And, Mountain Lion debuts a new Document Library where you can choose between iCloud documents and local files.

Mountain Lion also brings over more features from iOS, while tuning them to work better with a desktop operating system. While this includes some apps, the more-important changes are three new system-wide features: Notifications, Share Sheets, and Twitter.

Notification Center -- In the short time I’ve used Mountain Lion, I’ve found Notification Center to be highly useful, even if only a few applications support it. A notification is a brief message that appears onscreen, alerting you to something like a new incoming text message, a calendar event, or the next move in a multiplayer game. Fortunately, notifications are highly configurable, so you can control which aspects of your digital life become notifications. At the moment, Notification Center offers two types of notifications — banners that appear for a short time before disappearing, and alerts that stay until you click to close them or jump into the alerting application.

To see your notifications, you use a two-finger swipe from the edge of a trackpad or click the small notification icon located on the far right of the menu bar. Your Desktop slides a bit to the left to show a column of notifications in exactly the same style as the iOS Notification Center. It’s an extremely intuitive action and nice for glancing at things like new email messages or calendar appointments.

Since Apple Mail is likely to be a heavy pusher of notifications, it gains a new Favorites mark so you can pick which contacts’ messages trigger notifications. This is also used in Share Sheets, discussed below.

At first, I thought that bringing Notification Center to OS X would mean the end of the popular Growl notification tool, but the more I use Notification Center, the more I think that Growl retains an important role for those of us who need more flexibility in how notifications appear or advanced functions like sending notifications across computers.

As with most of the features I discuss in this article, Apple is supporting notifications with a new API for developers, so that developers can integrate notifications into their own programs.

Share Sheets -- Share Sheets adds a new button to supporting apps to “send” the current item to another application. This feature functions like the “Open In” feature in iOS, enabling you to share content directly between applications without cutting and pasting. (It’s kind of a simplified Services menu item, and will hopefully see more use than Services.)

Share Sheets focuses on photos, videos, links, and documents, and it enables you to share to other applications and online services, and even send files directly to AirDrop. Share Sheets are context-aware, so if you are sharing a note, you can send it to Mail or Messages, but not to iPhoto. For files in the Finder, you can share directly from Quick Look windows. And if you are on a Web page you can, with a few clicks, share the full page in an email message, or as a link in Twitter.

Did I mention Twitter?

Twitter, Safari, and Web Sharing -- As with iOS, Twitter is integrated deeply into Mountain Lion. Once you add your Twitter account in the updated Mail, Contacts, and Calendars preference pane, you can send content right to Twitter using Share Sheets.

See a Web page you like? You no longer need to cut and paste into your favorite Twitter application, but can instead send it directly from Safari. There’s also integration with your contacts (though I have yet to figure out how that works). When you create a new tweet, an input window pops up in whatever application you are in (instead of switching to a Twitter app), and you can choose to reveal your location down to the city level.

Apple also added support for Flickr and Vimeo accounts for photo and video sharing, along with support for some of the most popular Chinese photo and video sharing services as part of a series of system-wide enhancements for Chinese Mac users, showing how seriously Apple takes that market.

Safari steals a cue from Google Chrome and finally moves to a single address bar for search and Web addresses. Typing into the address bar will either take you to an address or run a search on the search engine of your choice. When I migrated my user account from my regular Mac, it retained Bing as my preferred engine.

Notes and Reminders -- Two iOS apps, Notes and Reminders, make their Mac debut. Notes replaces Stickies and is fully iCloud-compatible. Aside from keeping your notes in sync across different devices, Notes on the Mac supports more formatting, embedded images, and even file attachments. Since Stickies is gone, you can now “pin” a note to the Desktop. And yes, you can choose any font you want.

Since Notes on iOS doesn’t yet support this additional formatting, Apple “translates” the notes so they look appropriate on the smaller device. When I added an image, Notes didn’t display it on my iPhone, but I did see an icon that indicated there was an attachment.

Reminders also comes to the Mac and maintains nearly the same features as on iOS, minus location-based reminders. Both Notes and Reminders can work with CalDAV to support services other than iCloud.

Unified Messaging -- Goodbye iChat, hello Messages! According to Apple, over 100 million Messages users have sent 26 billion messages using iMessage on iOS. Messages completely overhauls iChat and unifies it with the FaceTime video chat app and the Messages text messaging app on iOS. And Messages is now available in beta for Lion users.

Aside from the visual improvements, Messages now completely supports iMessage messages on the Mac. This is unified with your other devices, so if someone sends a message to any of your iMessage email addresses, it will appear on all devices at once. Messages sent directly to your phone number, and not to an email address, appear only on your iPhone. You can send any attachment up to 100 MB, including video. All messages are encrypted from end-to-end.

Messages also supports group messaging, plus all the features of iChat. I was a bit worried that Screen Sharing would be gone (since that’s the only way I can keep certain family members online), but fortunately it’s still there.

Of all the changes, Messages hammered home to me the power of bouncing between devices without having to think about it. In one day, I tested it across my iPhone, iPad, and Mac, all without caring what was on or off, which app was open or closed. I merely moved from device to device while maintaining a continual conversation. It doesn’t matter if someone is on an iPhone or a Mac — I can message them, FaceTime them, and exchange files. That’s just a small example of the power of the cloud.

Gaming Gets a Power Up -- One of the most compelling demonstrations during Apple’s briefing was watching a head-to-head real-time race in Real Racing 2, with one user on a Mac, the other on an iPad, and the Mac streaming to a high-definition television.

Mountain Lion brings the iOS Game Center to the Mac. Aside from its social features, like finding friends and leaderboards, Game Center adds voice chat, status synchronization, notifications, and cross-platform multiplayer gaming. If your game supports it, you can hop off your iPhone and onto your Mac and pick up right where you left off.

And while it isn’t limited to gaming, the new AirPlay Mirroring in Mountain Lion means you can blast your achievements onto the big screen in 720p high definition. When sending to an Apple TV, AirPlay Mirroring will match your Mac’s display resolution, or you can set your Mac’s resolution to match the TV. (I was unable to test this, as AirPlay Mirroring informed me that my Apple TV wasn’t running the right software version.)

As a professional speaker, I find AirPlay Mirroring from a Mac to a TV interesting, but I would rather send from my iOS device to my Mac, which I would then connect to a conference projector. Then I could wander the stage while writing notes and drawing diagrams from the iPad onto the big screen.

Gatekeeper -- Gatekeeper is a significant advance in the history of Mac security. Admittedly, I’m somewhat biased since security is my day job.

Nothing can prevent malware from being written, but Gatekeeper should ensure that we never see a Mac malware epidemic. It limits the kind of downloaded applications that will run on your Mac. It’s an extension of the File Quarantine feature first introduced in 10.5 Leopard, and it enables you to limit applications to those that come from the Mac App Store, or a combination of the Mac App Store and identified developers who sign their applications with a digital certificate issued by Apple. For Mac users who want to avoid Trojan horses and other malicious downloads, Gatekeeper is a compelling security option. I’ve written a detailed description of Gatekeeper in “Gatekeeper Slams the Door on Mac Malware Epidemics” (16 February 2012).

The Future is the (i)Cloud -- Although a lot of the early coverage of Mountain Lion will focus on the influence of iOS on OS X, the real story is the growing role of iCloud. iCloud is the glue holding the Apple ecosystem together. Increasingly, Mac users’ settings, data, and communications are stored and managed in iCloud. In “The Future Is Disposable” (24 June 2011), I wrote:

Many vendors offer tools to host files and backups in the cloud, but Apple is taking iCloud in a totally different direction. Within Apple’s ecosystem the cloud becomes the center of everything — your apps, your data, and your settings. It won’t be done by file synchronization that extends our current model of computing, but by baking the concept of cloud access into everything we do at a fundamental level. Our devices finally become tools, not roach motels where the bits check in, but never check out.

If Apple pulls this off it will be one of the most ambitious leaps in the history of consumer technology. Just as the Mac changed desktop computing, the iPod changed the way we listen to music, and the iPhone transformed the mobile phone into something from science fiction, the overlap of iCloud, Lion, and iOS could change everything we know about personal computing.

Mountain Lion is the clearest indication yet that Apple shares this vision. If they succeed, how we use our computers, tablets, phones, and perhaps even televisions will never be the same.

Comments about OS X 10.8 Mountain Lion Stalks iOS
(Comments are closed.)

I expected many of these features (Messages, Notes) but I am pleasantly surprised at the inclusion of Air Play mirroring and a little nonplussed t Game Center which, as far as I can tell, has been a complete non-starter on iOS.

OS X Messages doesn't seem to be talking to iOS Messages in my limited testing. But this is day 1 of a beta product.

Working fine here, but of course it's several hours later. :)

Correction: the second paragraph should start, "This upgrade from 10.7 Lion to 10.8 Mountain Lion..."

Too darn many cats - fixed! It's actually getting hard for those of us who write about these things all the time to separate out all the different numbers and associated cats in our heads.

I understand that "Mountain Lion", "Puma" and "Cougar" are the names of the same animal. I see the name "Puma" is not trademark-able at all, but why not use the simple name "Cougar" this time? "Mountain Lion" (13 characters!) looks too long!
You're aware of the slang meaning of "cougar," right?
Adam Engst  An apple icon for a TidBITS Staffer 2012-02-17 05:19
Apple apparently registered Lynx and Cougar as trademarks but allowed them to lapse later.

In this case, I think it's clear that Apple is sticking with the pattern: Leopard and Snow Leopard, iPhone 3G and 3GS, iPhone 4 and 4S, leading into Lion and Mountain Lion.

Various Macs that can run Lion perfectly well cannot run 10.8 developer preview, which is rather annoying, including 2006 iMacs and MacBook Pros.

Have you seen an official requirements list? I've seen some coverage of it, but nothing from Apple, which I'd like before I update the article.
Tom Gewecke  2012-02-17 13:02
The only list from Apple is still non-public I think, in the seed channels.

Interesting info on GateKeeper and iCloud.

But who protects us from Apple? We now know that Apple hasn't exactly been steadfast in protecting us from having contacts appropriated, which is much more of a security problem for some of us than having our computer trashed. Will this system be useful if we don't wanna use iCloud, or can't because of business security issues?
Dave Laffitte  2012-02-21 13:34
Sounds like to me that with Gatekeeper we might be only a cat or two away from having to "jailbreak" our Macs to use apps that aren't Apple "approved".

I don't get that sense. Gatekeeper, and the option to run signed apps distributed outside the Mac App Store is very much not in that direction. And the option to run anything is absolutely still present.
S Mulji  2012-02-22 09:28
I predict by the time the next version of OSX comes out, the option to run absolutely anything disappears. You'll only be able to run signed apps distributed outside the Mac App Store or run Mac App Store apps. I can live with this. It's a good trade-off in the name of a more secure system.
Paul Corr  2012-02-21 16:36
I see the headline says "OS X 10.8". How does one say that? OS 'eks' 10.8 or OS 'ten' 10.8? I move between Mac, Win7, and Ubuntu and the Apple 'standard' for this has always annoyed me.
Adam Engst  An apple icon for a TidBITS Staffer 2012-02-22 13:48
As far as I know, it's still pronounced "Oh Ess Ten"

I can see where the icloud thing is going but am at a loss to understand why some form of simple file storage/transfer functionality cannot be present. We use idisks to simply share and transfer files between users of OS 9 and early and current OS 10 machines in different locations. We dont need or want synchronisation in these instances-just single location storage for multiple users and multiple file types. Why is something so simple so hard to do as part of the icloud model?
