Confirmed: iPad 3 Has a 2048x1536 Retina Display

---

Over the past couple of months, several photos of displays claimed to be for the iPad 3 have surfaced from various sources. Such parts leaks are typical with the device's expected debut early next month. While reports have claimed that these displays are high-resolution "Retina" displays, there has been no definite confirmation of these claims so far. MacRumors has now been able to obtain one of these iPad 3 displays and examine it under a microscope in an effort to determine whether it is indeed an ultra-high resolution Retina display. Physically, the purported iPad 3 display is the same size as the current iPad 1 and iPad 2 display at 9.7" in diagonal, and looks quite similar to the naked eye. However, when comparing the iPad 3 display to one from an iPad 2 under a microscope, the difference in resolutions becomes readily apparent, with the iPad 3 display's pixels appearing to be one-quarter the size of those on the iPad 2. Since we only had a raw iPad 3 display with no method to power it, taking high quality photos of the pixels was difficult. Still, even with the relatively poor lighting, you can easily make out the pixels on each display (made up of red, green and blue elements). We highlighted a cluster of 4 pixels (2x2) from the iPad 2 to compare it to the same area on the iPad 3. On the iPad 3, the same cluster was occupied by 16 pixels (4x4) -- exactly twice the resolution in each direction. Extrapolating out, the iPad 3 screen should carry a full resolution of 2048x1536, exactly twice the linear resolution of the iPad 1 and iPad 2 which is 1024x768. Such a screen should be able to display much sharper images as compared to the previous generation iPads. Apple is expected to introduce the iPad 3 with a media event on March 7, and the device is rumored to be carrying this high-resolution display, a new A6 system-on-a-chip, and LTE support for models with cellular data capabilities.

Foxconn Again Raises Wages for Entry-Level Workers

---

Reuters reports that Apple's manufacturing partner Foxconn has announced new wage increases for entry-level workers at its facilities in China, boosting pay anywhere from 16-25 percent. The increase, which comes as Foxconn is again under increasing global pressure stemming from reports on working conditions and worker rights issues at the company, is the company's third wage hike since 2010.

In a statement on Friday, Taiwan-based Foxconn said the pay of a junior level worker in Shenzhen, southern China, had risen to 1,800 yuan ($290) per month and could be further raised above 2,200 yuan if the worker passed a technical examination. It said that pay three years ago was 900 yuan a month.

Foxconn says that its wages are already far above minimum wage standards set by the government and that it will continue to focus on training and education for its employees. The company also provides room and board for its employees, although some have criticized the living conditions centered around cramped dormitory-style housing with various reports citing anywhere from eight up to fifteen or more beds per room. Foxconn made a significant boost to worker salaries in mid-2010 following significant scrutiny over worker suicides at the company's facilities. Initial reports had claimed that Apple was directly subsidizing those wage hikes, but Foxconn later denied those reports.

Apple Shuns The New York Times in OS X Mountain Lion Coverage Over Foxconn Reporting

---

With yesterday's announcements from Apple regarding its forthcoming OS X 10.8 Mountain Lion operating system, a number of media outlets had been provided with advance briefings and early copies of the software for the purposes of having reviews prepared and ready to go. When Apple published its press release and went live with OS X Mountain Lion information at 8:30 AM Eastern yesterday, the embargo was lifted and all of the pre-briefed publications immediately posted their stories on the topic. But one publication with a long track record of receiving favored access from Apple was missing from that group: The New York Times. An article from the Times' David Pogue was published about five hours after Apple's announcement, and it did not appear to include any specific details suggesting that he had received advance notice of the release. As reported by The Washington Post, Apple apparently shunned The New York Times over the newspaper's "iEconomy" series of articles that has focused in large part on working conditions in Foxconn's manufacturing plants in China.

Says a source at the Times: “They are playing access journalism...I’ve heard it from people inside Apple: They said, look, you guys are going to get less access based on the iEconomy series.” The on-the-record word from the New York Times differs only slightly from the not-for-attribution word: “We’re never happy with our access to Apple. We never have been. Apple is a difficult company to report on,” says Damon Darlin, the paper’s tech editor.

A decision by Apple to cut off access for a publication presenting the company in a less-than-favorable light should certainly be no surprise to longtime Apple watchers, and the technique is not an unusual one in business as companies constantly seek to ensure the most positive coverage possible. But as The Washington Post notes, the Times may be more than happy to lose some access to Apple in exchange for its ability to publish high-profile investigative reports such as its iEconomy series. Update: David Pogue did report on Twitter yesterday that he had been "running Mac OS X Mountain Lion for a week", so it is unclear exactly why his report was not ready to go when the embargo lifted and why his article did not offer any mention of a pre-briefing session as a number of the articles from other publications did.

Google Under Fire for Circumvention of Cookie Settings in Safari for iOS to Track Users

---

The Wall Street Journal reports that Google and several other advertising agencies have been discovered to be circumventing privacy protections in Apple's Safari browser for iOS devices in order to track users through ads on numerous popular websites. Google implemented the technique in order to embed +1 buttons on its ads, tricking users' systems into allowing cookies by using an invisible form submission to make Google's third-party cookies, which are blocked by Safari, appear as first-party cookies that are allowed.

To get around Safari's default blocking, Google exploited a loophole in the browser's privacy settings. While Safari does block most tracking, it makes an exception for websites with which a person interacts in some way—for instance, by filling out a form. So Google added coding to some of its ads that made Safari think that a person was submitting an invisible form to Google. Safari would then let Google install a cookie on the phone or computer. The cookie that Google installed on the computer was temporary; it expired in 12 to 24 hours. But it could sometimes result in extensive tracking of Safari users. This is because of a technical quirk in Safari that allows companies to easily add more cookies to a user's computer once the company has installed at least one cookie.

Google halted the practice once it was contacted by The Wall Street Journal about it, but has tried to downplay the impact of the issue.

In a statement, Google said: "The Journal mischaracterizes what happened and why. We used known Safari functionality to provide features that signed-in Google users had enabled. It's important to stress that these advertising cookies do not collect personal information."

In a companion blog post, The Wall Street Journal notes that the loophole that had permitted Google to bypass Safari's privacy protections has been closed in WebKit, the open source engine behind Safari, with the change having been made by two Google engineers. Consequently, Apple could and appears to be preparing to bring that fix to the public version of Safari.

An Apple spokesman said: “We are aware that some third parties are circumventing Safari’s privacy features and we are working to put a stop to it.” An update to the software that underlies Safari has closed the loophole that allows cookies to be set after the automatic submission of invisible forms. Future public versions of Safari could incorporate that update. The people who handled the proposed change, according to software documents: two engineers at Google.

The issue was discovered by Stanford graduate student Jonathan Mayer, who has also published an extensive blog post offering additional technical details on how Google and other advertising companies circumvented Safari's default cookie settings.

After Beta, Messages Will Be Exclusive to OS X Mountain Lion

---

Consomac has discovered that the OS X Lion Messages Beta that was released yesterday will not be a permanent feature for Lion users. Messages is the new iMessage-compatible version of iChat that will be included in OS X Mountain Lion. Apple also released a public beta version for OS X Lion users to try the app in the meanwhile. Based on the text strings found in the App's resources, it has been revealed that Messages will no longer be available for Lion users once the beta expires. Instead, Apple tells users to visit the App Store to purchase OS X Mountain Lion to continue to use Messages:

Thank you for participating in the Messages Beta program. With the inclusion of Messages in OS X Mountain Lion, the Messages Beta program has ended. To continue using Messages, please visit the Mac App Store and purchase OS X Mountain Lion.

OS X Mountain Lion will be a paid update and is expected to be released in late summer.

Apple's Messages Beta for Mac Includes Retina Sized Artwork

---

There has been plenty of evidence that Apple is planning for ultra high resolution Mac displays. In July 2011, we first detailed the existence of a new "HiDPI" mode in OS X Lion. This HiDPI mode was put in place in anticipation of the day that Macs would have double-resolution (4x the number of pixels) "Retina" Displays. As on the iPhone, Apple's plan was to make it easier on developers to jump to exactly 2x the linear resolution. For example, a 1440x900 pixel screen would go straight to 2880x1800 pixels. This would allow applications to automatically scale up by a factor of two without necessarily having to include high resolution artwork. Apple already made such a transition when going from the iPhone 3GS's screen (320x480) to the iPhone 4's Retina Display (640x960). In iOS, Developers can include high resolution versions of their artwork designated by the "@2x" suffix. From the developer documentation:

The inclusion of the @2x modifier for the high-resolution image is new and lets the system know that the image is the high-resolution variant of the standard image.

A look at some of the resources from Apple's new Messages app shows several graphics that come in multi-part TIFFs that include regular and double resolution versions. In fact, if you look at the information embedded within the images, you can see the resources were at one point named in the same "@2x" convention. So, it seems Apple's Messages App is already building in support for Retina displays on the Mac. Rumors have even suggested that we might see our first Retina Display Macs in 2012. One early report claimed Apple was working on a 2880x1800 MacBook Pro for the middle of this year.

iOS 5.1 'Pre-GM' Seed Leaked? Camera Slider, Japanese Siri

---

BlogdoiPhone claims to have somehow obtained a "pre-GM" version of iOS 5.1. GM refers to Golden Master version of the software which is typically the final production version. Only two new minor findings have been discovered. One is an ever-present camera icon on the lock screen of iOS 5.1. In present versions, the camera button only appears if you double-tap the home button. In this version of iOS 5.1, the camera icon is there at all times, but instead of a button, it's a slider. Sliding up on the camera icon seems to reveal the Camera app that allows you to take photos without fully unlocking the iPhone. Presumably, this is quicker than the existing solution which actually requires the Camera app to be launched. The other finding is the presence of a Japanese language setting in Siri. This has been rumored to be an impending feature for Siri. Apple has been seeding developers with versions of iOS 5.1 beta for some time, but the last release was January 9th. Apple may be waiting to release iOS 5.1 alongside the new iPad which is expected on March 7th. We're not certain about the legitimacy of BlogdoiPhone's screenshots, but carriers presumably do get early builds that may not make it into developer betas.

Gatekeeper Already Present in OS X 10.7.3, Available for Developer Testing

---

With developers needing to prepare for Apple's new Gatekeeper feature in OS X 10.8 Mountain Lion, Apple has revealed that the functionality is already baked into OS X 10.7.3 but hidden by default. Apple has instructed developers that they can enable Gatekeeper on OS X 10.7.3 from the command line in order to test the functionality.

Mac OS X users will soon have the option of turning on Gatekeeper, a new Mac OS X security feature. When a user does this, the system provides an additional measure of safety: it blocks that user from opening newly-downloaded applications that are not Developer ID–signed. In this scenario, the same user is easily able to launch downloaded applications that are Developer ID–signed. By default, Gatekeeper is not enabled in Mac OS X v10.7.3. For testing purposes, you can turn it on by using the new Mac OS X system policy control command-line tool, spctl(8).

Running the command "sudo spctl --enable" in Terminal will enable Gatekeeper on OS X 10.7.3, and the system can be turned off by replacing "enable" with "disable". With the system enabled, developers can then test how their applications will behave on systems using Gatekeeper. Warning for non-signed application download with Gatekeeper activated on OS X 10.7.3 Regular users obviously would have little use for activating Gatekeeper on their Lion systems at the present time, as developers have not yet had a chance to begin distributing updated versions of their applications integrating the new Developer-ID functionality. But its inclusion in OS X 10.7.3 is an interesting tidbit that will help developers test their applications with the new program and explains why the new Xcode 4.3 that supports Developer-ID requires OS X 10.7.3. In another sign of Apple's desire to quickly implement Gatekeeper, Panic's Cabel Sasser notes that Apple contacted select developers last week to invite them to learn more about the feature.

OS X Mountain Lion's Documents in the Cloud Simplifies File Access Across Devices

---

One of the major new features in OS X Mountain Lion is greater integration with iCloud, with one of the additions being new Documents in the Cloud functionality. As noted by John Gruber, the feature expands significantly on the existing feature that allows limited syncing and transfer of iWork documents across their iOS devices and Macs.

iCloud document storage, and the biggest change to Open and Save dialog boxes in the 28-year history of the Mac. Mac App Store apps effectively have two modes for opening/saving documents: iCloud or the traditional local hierarchical file system. The traditional way is mostly unchanged from Lion (and, really, from all previous versions of Mac OS X). The iCloud way is visually distinctive: it looks like the iPad springboard — linen background, iOS-style one-level-only drag-one-on-top-of-another-to-create-one “folders”. It’s not a replacement of traditional Mac file management and organization. It’s a radically simplified alternative.

iCloud Documents in Pages (Source: Pocket-lint) Apple is of course already extending this functionality beyond iWork in OS X Mountain Lion, with the iCloud file storage showing up in other apps such as TextEdit. Apple is also releasing APIs to allow third-party apps to take advantage of the feature. iCloud Document within a folder in TextEdit The functionality is naturally being compared to that of Dropbox, which allows users to save files directly to their Dropbox accounts for access anywhere, but Apple's new iCloud solution offers the advantage of displaying only those files intended for use with the app being used, helping to filter the list of documents and offering iOS-like folder organization of files.

Apple Officially Drops 'Mac' Name from OS X Mountain Lion

---

With the launch of Mac OS X 10.7 Lion in the middle of last year, Apple was clearly trending towards dropping the 'Mac' From 'Mac OS X', which has been the name of the Macintosh operating system for more than 10 years. Though it still used the 'Mac OS X' naming scheme in press releases, Apple called the new system 'OS X Lion' on both the main product webpage and the Mac App Store product page [Direct Link]. As The Verge points out, Apple has completed the transition to 'OS X' across both the Mountain Lion product pages, and the press release announcing the developer preview.

We confirmed the official name change with Apple, who told us that the preferred full name is "OS X Mountain Lion".

The Macintosh (as Tim Cook prefers to call it) brand is still alive and well, though Apple seems to be focusing that term on hardware, instead of software. Lion was the beginning of a unification of sorts between the Mac OS and iOS. It was, as Steve Jobs put it, what would happen if a MacBook Air and an iPad "hooked up". iOS is based on Mac OS X and, at a fundamental level, there are more similarities than differences between the two operating systems. Dropping 'Mac' completely from the name of the OS solidifies the subtle, but important, distinction between hardware and software. OS X Mountain Lion is expected to be released later this year.

Software Update to Move Inside Mac App Store in OS X Mountain Lion

---

Apple's Software Update has long been the primary method for users updating their systems, with the tool accessible through the Apple icon in the menu bar offering automatic weekly checks for new software updates from Apple. But as shown by iClarified, Apple is doing away with the standalone Software Update tool in OS X Mountain Lion and integrating it directly into the Mac App Store. Pocket-lint has more on Apple's decision:

Currently Apple's Software Update system in Mac OS X 10.6 Snow Leopard, and Mac OS X 10.7 Lion force users to use a dedicated update procedure that constantly checks to see if updates are available. Apple now feels, it seems, that this way of doing things might be slightly confusing to users coming from an iPhone or iPad who are used to seeing updates for apps appear in the App Store rather than buried elsewhere. Explaining to Pocket-lint in a behind-closed-doors briefing for the new developer preview of Mac OS X Mountain Lion, Apple has told us that the new method will offer updates to the OS and Apple applications in a similar way to how it does on iOS via the App Store, but in this case via the Mac App Store.

The report notes that the move appears to require that users sign up for an Apple ID if they have not done so already in order to access the updates, and also encourages them to keep the Mac App Store within easy access in their Docks so that they will notice badges informing them of available updates.

OS X Mountain Lion Limits Apps to Mac App Store, Signed Apps by Default

---

One of the significant new features in OS X Mountain Lion is Gatekeeper, a new security system to help keep users from installing nefarious applications on their machines. The new system relies not only on Mac App Store distribution as means of vetting apps, but also on a new "identified developer" program under which developers distributing their applications outside of the Mac App Store can register with Apple and receive a personalized certificate they can use to sign their applications. Apple can then use that system to track developers and disable their certificates if malicious activity is detected. As Macworld notes in its review of Gatekeeper, OS X Mountain Lion's default setting will be to only allow initial launching of apps either downloaded from the Mac App Store or which are digitally signed under Apple's identified developer program. Users will be able to access Gatekeeper's settings in the Security & Privacy section of System Preferences, where they will also be able to choose from an even stricter setting that will allow for installation of Mac App Store apps only or a looser setting that will allow all applications to be installed and launched.

Located in the General tab of the Security & Privacy preference pane is a setting called “Allow applications downloaded from,” with three options: Anywhere: This choice uses the same set of rules as every previous version of Mac OS X. If an app isn’t known malware and you approve it, it opens. Mac App Store: When this choice is selected, any apps not downloaded from the Mac App Store will be rejected when you try to launch them. Mac App Store and identified developers: This is the new default setting in Mountain Lion. In addition to Mac App Store apps, it also allows any third-party apps that have been signed by an identified developer to run.

For users on the default setting, they can bypass the initial Gatekeeper check the first time they launch an unsigned third-party app by right clicking on the app itself and choosing the "Open" command. Once the application has been opened one time, Gatekeeper no longer has any control over it. As for apps that are signed by an identified developer, Macworld notes that OS X Mountain Lion will perform a daily check with Apple's servers for blacklisted developer signatures, and if an app from a blacklisted developer is installed on the user's system it will not open. Importantly, Apple's identified developer program does not involve any sort of vetting on Apple's part, as certificates are automatically issued upon request and can be freely used by the developers. But what the program does do is provide a way for Apple to link specific developers to specific apps and use Gatekeeper to revoke application functionality should a developer be discovered to be distributing malware.
