As nifty as the new Haswell-based MacBook Air units are, there may be another bug to contend with.

Per The Unofficial Apple Weblog and MacRumors, it seems that the MBAs with Haswell processors have issues with Adobe’s flagship software. In particular, many MacBook Air owners noticed severe screen flickering while using brush tools in Photoshop. When news of the flickering first surfaced, an Adobe representative said he believed a GPU issue or a driver bug was causing it.

It’s been suggested that that the flickering is a result of a software glitch. Apple has released a new build of OS X 10.8.5 to developers and the Photoshop flickering issue appears to be resolved, as reported by MacRumors:

“Today, MacRumors tipster Todd Davis tells us the flickering issue has been fixed in the OS X 10.8.5 beta released to developers today. The bug made Photoshop nearly unusable for a number of MacBook Air users. Some users have previously suggested that upgrading to the developer release of OS X Mavericks solved the problem, so the fix may be a matter of Apple pushing upgraded code sooner than it planned.”

There’s no word on when users can expect to see OS X 10.8.5 released to the general public. If the latest build does indeed fix the MacBook Air/Photoshop flickering issue, chances are good that Apple will push it out sooner rather than later, since it doesn’t want their newest Haswell laptop to present problems with such popular software.

Stay tuned for additional details as they become available.

Rumor: Apple considering switch to IGZO displays to boost next-gen MacBook Pro battery life

The next-gen MacBook notebooks could possess even longer lasting batteries.

Per Korea IT News, Apple is once again rumored to be considering indium gallium zinc oxide (IGZO) LCDs, this time for inclusion in not only upcoming versions of its iPad, but also in its forthcoming MacBook Pros. A recent report has the Cupertino company talking with Sharp and LG Display in preparation for wider manufacture.

The new MacBooks would reportedly be scheduled for release some time early in 2014, though the report gives no word on when IGZO-packing iPads would be set for release. The latest speculation surrounding the iPad does make mention of reduced backlighting and improved battery life, both of which could be outgrowths of IGZO technology.

An oxide semiconductor, IGZO is about 10 times faster in electron mobility than an amorphous silicon semiconductor. This allows the technology to consume far less power in operation. IGZO also requires smaller wiring, which also contributes to its lower power consumption.

The panels are significantly more expensive than traditional LCDs, though, so that could represent an obstacle for Apple in bringing them to market in the MacBook Pro line. Some estimates have Apple paying 1.5 to two times as much for the same panel sizes seen in current models.

A switch to IGZO could be in keeping with Apple’s already established goals for this generation of MacBooks. When introducing the 2013 MacBook Air, Apple made sure to note that the inclusion of Intel’s new Haswell processors had boosted overall battery life to 12 hours for the 13-inch model. The inclusion of less power-intensive displays could push the next generation of MacBook Pros to even greater heights.

Apple has long been rumored to have been looking at IGZO technology for future devices. Previous rumors have focused on the iPhone or iPad.

Mavericks is coming…

Per MacNN, Apple has posted OS X 10.9 Mavericks Developer Preview 3 on Monday. While it is too soon to notice any significant changes or improvements, the beta is focused on compatibility and performance issues, as well as integrating the forthcoming “iCloud Keychain” feature. The update is still dealing with assorted known issues, including some that render it incompatible with even the last Mavericks and iOS 7 betas. Installation on production machines remains strongly discouraged.

The update, which is just over 1GB in size, doesn’t support virtual machines made by VMWare Fusion, nor does Adobe’s After Effects CS6 work properly. A number of functions in DP3 are not backwards-compatible with previous versions — such as new Fusion Drive volumes, screen recordings, Recovery Partition reinstalls and iCloud Keychain. The latter, an expansion of the ability to sync keychains between devices, still has a number of serious known issues.

The iCloud Keychain proposes to move the centralized storage of secure passwords, website usernames and other important data to iCloud, with entries encrypted using 256-bit AES. This enables users to take more advantage of the built-in Password Generator that creates unmemorable complex passwords for online accounts, since users don’t have to remember the password itself, just the one master password that unlocks the keychain and can be used across any devices the user has.

The release notes refer to issues with QuickTime Player, Aperture, Photoshop, Maps and others. The new update does include a newer version of OpenSSH, 6.2p2, but also lists a number of odd bugs such as “the headphone port on the new 2013 MacBook Air will not operate unless headphones are present at boot” and “on some machines, frequently sleeping and waking may result in the machines restarting,” indicating that the latest release is still far from being ready for public consumption. Migration from Windows is still not supported, and network migration from earlier versions of OS X requires a Migration Update (for Snow Leopard and later) that is only available from the Mac Dev Center.

The forthcoming Mavericks promises users long-requested features such as Finder Tabs and better multi-monitor support, extensive efficiency routines that should prolong battery life, improved Maps, a faster Safari, iBooks for the Mac and many other new and improved features. It is expected sometime in the early fall, although no exact release date has been released.

The numbers tell the truth.

Per MacNN, Apple will hold its next quarterly earnings call with investors on Tuesday, July 23, where it will discuss its fiscal third-quarter results. According to its own estimates, it expects to report between US$33.5 billion and US$35.5 billion, a drop from the previous quarter but a realistic figure in light of no refreshed iPad or iPhone, the two primary drivers of Apple’s income. While the latest MacBook Air revision has garnered significant praise for its various improvements, it emerged at the very tail end of the quarter and thus didn’t influence sales.

Possibly affecting sales of other Apple products is the expected drop in sales that comes ahead of new iOS device models. Apple has already said that new products will be coming this fall, which is taken to mean the latest iPhone, iPad and possibly some entirely new devices — including a long-rumored Apple television or smartwatch. Another keenly-anticipated release is the acceptance of the new iOS 7, not to mention the long-overdue Mac Pro overhaul, which will test how professional users will adapt to the re-designed machine. Primarily, however, investors will be watching to see if Apple can continue its remarkable iOS platform US sales growth in the face of competition and a lack of any new product in the quarter.

In the previous quarter, Apple saw both good news and bad: revenues were up, as were iPad and iPhone sales (above analysts’ predictions), but Mac sales were basically flat and net profit was down slightly for the first time in a decade, a trend that is expected to have continued over the past three months. Analysts have reported that Apple has ordered fewer iPhones for the upcoming quarter, signalling that it expects further erosion of iPhone sales ahead of its eventual announcement of the next model.

Margins are expected to be around 36 percent, with operating expenses bubbling just under US$4 billion. The conference call is schedule to take place at 2PM Pacific/5PM Eastern on July 23.

Apple working on 802.11ac bug fix for mid-2013 MacBook Air users, sends out limited invitation to test update

If you’re having trouble with the Wi-Fi on your new mid-2013 MacBook Air, a fix may be on the way.

Per AppleInsider, in a likely response to reports of 802.11ac Wi-Fi issues with its latest MacBook Air refresh, Apple late Friday began sending out invitations to select users, offering inclusion in the AppleSeed Program to test an upcoming Wi-Fi centric software update for the notebook.

Sources who received the email said that Apple will provide selected customers with a pre-release version of the “MacBook Air WiFi Update 1.0″ to install and use on their new machines, asking that they give feedback on any bugs found during the testing process.

While not explicitly stated in the AppleSeed invite, it is thought that the update relates to recent Wi-Fi connectivity issues some customers have experienced with Apple’s implementation of the fairly new 802.11ac wireless standard.

The recently-released 11- and 13-inch MacBook Airs are the first Macs to implement the fast wireless protocol which, when combined with the new AirPort Extreme or AirPort Time Capsule, can reach theoretical speeds of up to 1300Mbps.

Although the technology has promise, a growing number of owners have complained of throughput limitations related to 11ac, with some reports speculating the wireless stack in OS X is at least partially to blame.

A thread on Apple’s Support Communities webpage appears to confirm the AppleSeed invitations, but offers little information on the software. Those who have already agreed to Apple’s terms said the company has yet to activate the invitation codes or send out the software.

In December 2012, Apple released a similar Wi-Fi compatibility update for Mac two months following the debut of the MacBook Pro with Retina display. At the time, owners of the then-new machine complained of problems recognizing 802.11n networks in the 5GHz band.

Study finds mid-2013 MacBook Air’s 802.11ac Wi-Fi speeds throttled by bug in OS X

Even in the event that the Wi-Fi connectivity issues on the mid-2013 MacBook Air notebooks are hardware-based, the underlying operating system software is apparently throttling potential data speeds on the new networking protocol.

Per AnandTech and CNET, a series of tests by AnandTech confirms that much of the Wi-Fi speed throttling is software-based. The new MacBook Air was announced by Apple at the recent Worldwide Developers Conference, and in addition to extended battery life, the new systems include support for 802.11ac Wi-Fi networking, which supports up to three times faster data rates in comparison with 802.11n.

In testing, AnandTech noticed that the link speeds of the systems are very high, at an average of about 533Mbps, but when transferring files over standard networking protocols, the speed drops to about 169Mbps at its maximum. This is over three times less than the expected speeds.

In investigating the issue, AnandTech discovered that an apparent bug in OS X limits the TCP window size (the maximum data that can be sent at a time) to a maximum of 64KB, which is far less than the 256KB needed to meet the speed capabilities of the 802.11ac connection.

As a result of this finding, AnandTech shows that in its current state, while the 2013 MacBook Air will still give fast file transfers, these will be limited to about 21MBps, instead of the more than 50MBps expected. Luckily, this limitation being in software means the fix should be easy, and it may be only a matter of a quick update for these systems to realize their full potential.

Apple looking into mid-2013 MacBook Air Wi-Fi issues, “capturing” units for study

This might be why your friends, the ones who wait a month or two after a brand new product hits the market, could be right…

Per 9to5Mac, over the past few days, a notable amount of users have complained about Wi-Fi issues plaguing the new 11-inch and 13-inch MacBook Air models released during the week of WWDC. Besides less-battery-intensive chipsets, the marquee feature of the new MacBook Air revolves around faster Wi-Fi connectivity thanks to new 802.11ac cards. As with any new product, bugs are plausible. It’s also been noted that new reports claim that the MacBook Air WiFi issues are due to networking issues in Apple’s OS X software.

The following facts are currently in place:

In the United States, Apple Geniuses and Advisors should capture MacBook Air (13-inch, Mid 2013) and MacBook Air (11-inch, Mid 2013) computers with any Wi-Fi issues.

According to a source at Apple, the company is working to independently identify what exactly is causing the new Wi-Fi-related problems. According to the source, AppleCare and Apple Store Genius Bar employees have been instructed to “capture” affected MacBook Air units. These units will then be sent back to Apple for further testing so a solution could hopefully be achieved. While Apple is asking AppleCare and Genius Bar staff to “capture” units facing problems, that does not mean Apple is confirming the new MacBook Air is flawed. This points to Apple pushing to determine why at least some units are seeing Wi-Fi problems.

There have also been reports of at least a couple of customers facing MacBook Air WiFi issues who have successfully swapped out their notebooks for new ones. One of these people has said that AppleCare provided them with a complementary USB-to-Ethernet adapter so the new MacBook Air could connect to the internet without Wi-Fi. Apple also informed these people that their original laptops have been “captured”.

If you’ve picked up Apple’s latest MacBook Air notebook and have any feedback to provide about its 802.11ac Wi-Fi performance, please let us know in the comments.

Growing number of users cite Wi-Fi connectivity issues with 802.11ac-equipped MacBook Air notebooks

To be fair, this is what they invented firmware updates for.

Per Gizmodo, some early adopters of Apple’s latest MacBook Air models have found their new thin-and-light notebook will unexpectedly and repeatedly drop its wireless connection.

A growing discussion thread on the Apple Support Communities website details the connectivity problems being experienced by numerous users. The problems appear to apply to both the 11- and 13-inch varieties of the recently updated notebook lineup.

In addition, an anonymous source from an Apple retail store in London said that their store has had complaints about wireless connectivity for the new MacBook Airs that are “well above average.”

In the thread, users say they’re experiencing the problems across a range of routers, including Apple’s own AirPort accessories. Users say they can initially connect to a Wi-Fi network, but that connection will drop after a short period of use.

At the moment, there doesn’t appear to be an available solution that addresses the problems seen by all users, though some have had success with various routers or even different placement of the MacBook Air.

The updated MacBook Air lineup launched last week at Apple’s annual Worldwide Developers Conference. In addition to faster 802.11ac connectivity, the notebooks also feature Intel’s latest Haswell processors, helping to enable battery life as great as 12 hours.

The new MacBook Airs are also priced US$100 less than their predecessors, with the new low-end US$999 11-inch model packing 128 gigabytes of flash storage.

Intel-based MacBook Air batteries show best-ever test results according to Macworld Lab

The new MacBook Air batteries have been tested.

And you’ll probably like the results.

Per Macworld, the Macworld Lab has completed its run of tests on Apple’s new battery for its updated Haswell-based MacBook Air notebook. And while Macworld Lab didn’t experience the 12-hour battery life cited by Apple, the tests do show that the new MacBook Air lasts considerably longer than before. The results were better than anything seen before by the lab.

The tests were run with the brightness set to maximum and made sure that automatic brightness adjustment was off, backlit keyboards were off, and Screen Saver was set to never start.

In the first test, the lab looped a movie clip in full screen mode with Wi-Fi disabled. The new 11-inch MacBook Air lasted 6 hours and 6 minutes, compared to just 3 hours and 34 minutes for the 2012 model. The new 13-inch standard configuration MacBook Air lasted 8 hours and 18 minutes, 36 percent longer than the new 11-inch MacBook Air, and 65 percent longer than last year’s 13-inch MacBook Air. Compared to a 2013 13-inch Retina MacBook Pro, the 13-inch MacBook Air lasted 75 percent longer.

The lab also ran the tests on “ultimate” configure-to-order (CTO) MacBook Air models from this year and from last year. There wasn’t too much of a battery life hit on the new CTO model compared to the standard configuration; the standard configuration model lasted just 11 minutes longer than the CTO unit that has a faster processor, more RAM, and twice the hard drive capacity. Comparing this year’s CTO “ultimate” to last year’s, they saw that the new model lasted 65 percent longer.

The second run of tests used Futuremark’s free Peacekeeper browser test, which has an option to run the online test repeatedly and report the time at which the system being tested stops responding. This test is much more taxing than the movie playback, using more of the system’s memory and processor. Hence, the lab found that the notebooks couldn’t last as long when running the Peacekeeper test, but did find that the performance still scaled as expected.

In the Peacekeeper tests, the new 13-inch standard configuration MacBook Air lasted the longest at 5 hours and 45 minutes, which was 2.5 hours less than in the movie test. The new 13-inch standard configuration model lasted 41 percent longer than the new 11-inch model and 25 percent longer than the new CTO MacBook Air. It should be pointed out, however, that the CTO Air outscored the new stock 13-inch MacBook Air by about 20 percent in the tasks that Peacekeeper repeatedly runs during its battery test. The new standard configuration 13-inch Air lasted 63 percent longer than last year’s 13-inch MacBook Air and 67 percent longer than the 13-inch Retina MacBook Pro.

The increased battery life is the result of two under-the-hood changes to the MacBook Air. First off, there is more battery capacity. iFixit’s teardown demonstrated that the new models using slightly higher capacity batteries. Second, the new MacBook Air has also switched from using Intel’s third generation Ivy Bridge Core processors to fourth generation Haswell processors. A key difference between the generations is decreased power consumption, which results in increased battery life on the portables it powers.
