Rumor: Next-gen MacBook Air notebook to once again include backlit keyboards

The new MacBook Air: It might just feature the shiny coolness that is a backlit keyboard.

With the release of new models later this month, Apple is set to reinstate a feature to its MacBook Airs that went missing when the company overhauled the ultra-thin notebooks into more cost-affordable products late last year.

Per AppleInsider, according to sources close to the story, backlit keyboards will join the string of hardware enhancements planned for the new 11.6- and 13.3-inch notebooks, which are also expected to adopt high-speed Thunderbolt ports, an upgrade to Intel’s Sandy Bridge architecture, and possibly high-speed 400MBps flash memory.

The omission late last year of keyboard backlights — which help illuminate the keys on a keyboard in dim lighting scenarios — from Apple’s current lineup of MacBook Airs was particularly glaring given that all three iterations of the first-generation of MacBook Airs (Early 2008 to Mid-2009) included them as standard features.

Given Apple’s energy saving controls, software expertise, and the nominal cost associated with including keyboard backlights, it was never particularly clear why Apple opted to leave out the feature when it redesigned the MacBook Air line last October. One industry watcher even went as far as to call it “planned obsolescence” on Apple’s part.

Nevertheless, people familiar with the matter say Apple’s white 13.3-inch MacBook will once again be the only notebook from the company to lack keyboard backlights once the new Airs make their debut sometime during the week of July 21st.

According to sources, Apple has been holding off shipments of roughly 400,000 of these new MacBook Airs until it can image them with the finalized Golden Master build of Mac OS X Lion, which privately began making its way to developers last week.

Stay tuned for additional details as they become available.

iFixIt performs teardown of Apple’s Thunderbolt cable, discovers receiver/transceiver system inside

When in doubt about a new piece of hardware, take it apart and study it.

Once again, the guys at iFixIt performed a full teardown of a new Apple item, this time dissecting Apple’s just-released $49 Thunderbolt cable to reveal an “active cable” with transceiver chips on each end.

iFixit took apart the new cable on Wednesday and discovered two Gennum GN2033 Thunderbolt Cable Transceiver chips, other much smaller chips and “tons of little resistors” tucked into the metal connector.

The teardown experts were prompted by a tip from ArsTechnica, who had been told by a support technician for storage maker Promise that Apple’s Thunderbolt cable is a “smart cable” with internal firmware.

Apple released the Thunderbolt cable on Tuesday, alongside the first compatible peripherals–external RAID systems from Promise, which range in price from US$999 to US$1,999. Early tests of the Promise systems have revealed blazing fast write speeds of up to 700MB/s, as much as 21 times faster than FireWire and USB 2.0.

The Gennum web site describes the cable’s transceiver chips as a requirement for the cables due to “the unprecedented speed of the new Thunderbolt technology places unique demands on the physical transmission media. The GN2033 provides the sophisticated signal boosting and detection functions required to transfer high-speed data without errors across inexpensive Thunderbolt copper cables.”

Sources within the telecom industry told ArsTechnica that active cables are usually used at data rates in excess of 5Gbps. Chips at either end are calibrated to the attenuation and dispersion properties of the wire in order to “greatly [improve] the signal-to-noise ratio.”

Intel has also reportedly chosen to use active cabling for “future optical-based iterations of Thunderbolt,” the report’s source added. Though passive optical cabling is more common, active optical cables could allow fiber optics to be coupled with electrical cabling for power transmission. Additionally, “current electrical ports can be forward compatible with future optical cables” if active cabling is used, said the source.

On the more consumer end, LaCie has promised a Thunderbolt solid-state drive is coming this summer. A recent demo of the drive reached read speeds of 827.2MB/s.

Intel and Apple worked together to develop the specification, with Intel providing its “Light Peak” technology and Apple offering its Mini DisplayPort standard. Thunderbolt drives two separate 10Gbps links, one for displays and one for PCI-Express devices, and could reach speeds of up to 100Gbps when the cables transition from copper to optical.



Similar to Apple’s experience with its in-house developed FireWire standard, the company has a fine line to walk in making Thunderbolt a unique value-add for Macs while still driving widespread adoption of the standard to ensure a large enough market for a range of third-party peripherals. Currently, the Mac maker is the only supplier of Thunderbolt cables.

Earlier this week, Sony announced a new VAIO Z laptop that implements a proprietary version of Thunderbolt. The electronics giant pulled a similar maneuver with its custom version of FireWire, called i.Link.

Initial tests show promising Thunderbolt speeds, ability to boot off new port

A newly published series of test results from the cool cats at AnandTech shows Apple’s newly adopted Thunderbolt technology blows FireWire 800 out of the water with data transfer speeds to an external RAID system at 700MB/s.

After the release of Apple’s Thunderbolt cable on Tuesday, early impressions have begun to surface on the Web. The AnandTech staff got their hands on both the US$49 cable and the US$1,999 Promise Pegasus R6 system and have subsequently stated that they are able to write to the 12TB RAID array at nearly 700MB/s while on a notebook. The speed obliterated that of the commonplace USB 2.0, as well as FireWire 800.

In his testing, Anand Shimpi also revealed via Twitter that external drives can be booted from via Thunderbolt. This makes it possible to have a full install of OS X, which includes all your files and apps, stored on a Thunderbolt external drive. This in turn would allow you to take your computer everywhere you go, and run it on another Thunderbolt-equipped Mac.

Per Macworld’s test of the new cable with the same RAID system, their detailed results show Thunderbolt is between 4 and 21 times faster than FireWire & USB 2.0. When compared to both on a 2.2GHz Core i5 Macbook Pro, Thunderbolt could write a 2GB file at 210.5 MBps.

On the other hand, USB 2.0 could only stretch to 29.7 MBps, a result that is 7.09 times slower. FireWire 400 could write the file at 30.2MBps, 6.97 times slower & FireWire 800 wrote the file at 47MBps, or 4.47 times slower.

Also Tuesday, Apple issued a series of 10 questions and answers related to Thunderbolt. Most of the information presented was already announced, like the fact that the cable offers two independent channels of 10GBit/s.

One new bit of information from the series of answers is a possible drawback for high-end Macbook Pro users: A PCI Express Card in the Express Card slot cannot be operated if the system is connected to a Thunderbolt device. Apple recommends disconnecting the device if you are going to use the Express Slot.

The full list of info is included below:

1. What is the maximum bandwidth supported by Thunderbolt to Thunderbolt cable (2 m)?

Thunderbolt utilizes two separate 10Gbps links—one for displays and one for PCI-E device trafffic—for throughput of up to 10 Gbps between Thunderbolt capable devices and your Mac. Some devices not made by Apple may support different bandwidth rates; consult any documentation that came with your Thunderbolt-enabled device for information specific to your device. Choose the Disk Activity tab in Activity Monitor to read current disk activity statistics, which may be helpful to determine disk activity with storage devices using Thunderbolt. Some storage devices may have a maximum transfer rate lower than the bandwidth potential of Thunderbolt.

2. What is the proper way to insert a Thunderbolt cable into my Thunderbolt-capable device or Mac?

The Thunderbolt symbol should be on the top of the connector. You can plug either end of the cable into a device or Mac; the connectors on each end are the same. Do not force the Thunderbolt cable into your Thunderbolt-capable device or Mac computer’s Thunderbolt port.

3. How do I confirm a Thunderbolt-enabled device is connected to a Mac?

Open System Profiler and examine the Thunderbolt tab for a list of any connected Thunderbolt devices.

4. Can I use a Thunderbolt cable to connect a Promise, La Cie, or other third-party storage device that uses Thunderbolt?

Yes. You can use a Thunderbolt cable to connect any Thunderbolt-enabled device or Mac.

5. Is there a maximum supported length for using Thunderbolt cables with Apple products?

Thunderbolt cables should not exceed two meters for maximum performance. Apple Thunderbolt to Thunderbolt cable (2 m) is two meters in length. Some Thunderbolt devices include an extra port you can use to connect other Thunderbolt devices downstream with additional Thunderbolt cables.

6. Why is there a black screen when I use a Thunderbolt cable to connect to an Intel-based iMac that supports Target Display Mode?

Although a Thunderbolt cable will fit into Mini DisplayPort connections, only Mini DisplayPort cables can be used to in Target Display Mode with an iMac (Late 2009) or iMac (Mid 2010) connected to a Thunderbolt-enabled Mac; iMac models produced before 2011 do not support Thunderbolt cables or devices. If you have an iMac (Late 2009), make sure you have the 27-inch SMC iMac Firmware Update 1.0 installed to avoid issues waking from sleep in Target Display Mode.

7. What do I do if my Mac doesn’t have a Thunderbolt option in System Profiler and no connected devices seem to be recognized?

For Mac computers with Thunderbolt, run Software Update to install any available updates to use Thunderbolt devices with your Mac.

8. I’ve installed all available updates, but no Thunderbolt devices are recognized when I connect them with Thunderbolt to Thunderbolt cable (2 m).

Try using a different a Thunderbolt cable, using a Mini DisplayPort cable, or—in the case of a storage device—try using another supported connection method, such as USB or FireWire.

9. Can I use Target Disk Mode with a Thunderbolt to Thunderbolt cable (2 m) and a third-party storage device that uses Thunderbolt?

Yes. The Thunderbolt logo should appear with the FireWire logo when you start up a Thunderbolt-enabled Mac and have a Thunderbolt storage device connected. If you have both a Thunderbolt and a FireWire storage device connected and enter Target Disk Mode, the Thunderbolt-enabled device will be the default. If you disconnect either a Thunderbolt or FireWire storage device after successfully entering Target Disk Mode, the corresponding icon should disappear from the display.

10. Can I use Thunderbolt to Thunderbolt cable (2 m) with supported versions of Microsoft Windows on a Thunderbolt-capable Mac with Boot Camp?

Yes. Learn more about using Thunderbolt with your Mac running Windows with Boot Camp.

It’s the rumors that keep life interesting.

And “Gossip Girl” still on the air (for better or for worse).

Per the cool cats at 9to5 Mac, a new series of rumors has narrowed down the expected ship date of the next-generation MacBook Air, complete with Thunderbolt and Sandy Bridge architecture, to mid-July. The tip emphasized that the systems would be virtually identical in external design outside of the switch from Mini DisplayPort to Thunderbolt.

The systems are already known to be shipping with Mac OS X 10.7 (“Lion”) and hint that Apple will be making the new OS available on or near the same day. Intel’s newly shipping low-voltage Core i5 and i7 chips are widely presumed to be coming along, although Apple may only use these for the 11-inch Air and reserve existing, faster 2.1GHz and 2.3GHz processors for the 13-inch system.

The new Air is expected to be a major leap in performance. Although the Intel integrated graphics will just be on par with the GeForce 320M they replace, the underlying processors will bring Apple’s systems from behind equivalents in performance to equivalent or sometimes ahead. An update is also an opportunity to close gaps in RAM or storage.

One rumor has the 11-inch Air dropping to US$899 to lure in more buyers. Apple’s typical pattern is more often to upgrade features for the same price, and it may consider this a top priority given just 64GB of storage in its starter model.

Stay tuned for additional details as they become available.

National retailer Best Buy has put a hold on online MacBook Air orders, providing further evidence that Apple plans to release an updated version of its diminutive laptop.

Per Electronista, Best Buy’s listings for the current-generation MacBook Air are now listed as “Not Available for Shipping.” Meanwhile, all MacBook Air models on Apple’s Online Store remain ready for shipping.

Best Buy continues to offer the portables in its brick-and-mortar retail stores, though some locations have reportedly run out of stock. In the U.K., the big-box retailer allows orders for a MacBook Air with 128GB of storage, but only with in-store pickup at certain locations.

Apple is expected to refresh the MacBook Air line with Intel’s Sandy Bridge processors and the addition of the Thunderbolt port. However, sources close to the story have stated that Apple is waiting until it can load a Gold Master build of Mac OS X Lion onto the notebooks before releasing them.

Mac OS X Lion is due for release on the Mac App Store in July. As a major upgrade to Apple’s flagship desktop OS, Lion will include more than 250 new features such as full screen apps, additional multi-touch gestures and Mission Control.

Intel lists three new processors that could find their way into next-gen MacBook Air

With everything that’s being said about Apple’s upcoming next-gen MacBook Air, it’s time to meet the potential processors for the notebook.

Per CNET, Intel has added three new high efficiency Sandy Bridge CPUs to its product catalog, likely representing the chips Apple will use in its next refresh of the light and thin MacBook Air.

The ULV (ultra low voltage) parts consume only 17 watts, making them suitable for the slim design of the Mac Book Air, as opposed to the mainstream Sandy Bridge chips Apple uses in its full size MacBook Pro lineup.

The standard Sandy Bridge chips in Apple’s Pro notebooks dissipate 25 to 35 watts, making them too hot (and too battery taxing) to use in the considerably thinner Air machines.

The new lineup consists of three part numbers:
- Core i7-2677M: dual cores running at 1.8 GHz (peaking to 2.9GHz), 4MB cache, listing for US$317

- Core i7-2637M: dual cores running at 1.7GHz (peaking to 2.8GHz), 4MB cache, listing for US$289

- Core i5-2557M: dual cores running at 1.7GHz (peaking to 2.7GHz), 3MB cache, listing for US$250

Intel sees a big market for notebooks similar to Apple’s MacBook Air, which the chipmaker calls “ultrabooks.” When Apple first released the Air, it was criticized for not being thin enough and giving up too many features while using a full sized keyboard.

Apple has since made the Air lineup thinner and reduced the price while retaining a full size keyboard and moving exclusively to SSD storage, which supports very fast booting, wake and program launching.

The report cited analyst Doug Freedman of Gleacher & Company, who refers to machines like the Mac Book Air as “SSD notebooks,” as commenting that “In the 4-year lifespan of [Apple's] iconic MacBook Air, units sold as a percentage of its total notebook supply was 8 percent in 2008, 9 percent in 2009, and 17 percent in 2010 to an estimated 48 percent in 2011.”

“We expect total notebook SSD penetration at a conservative 5 percent in 2011 growing to 30 percent in 2014,” Freedman stated. He noted that Intel is planning to bundle its own SSD storage devices with its CPUs to sell PC makers packages of components, something the company already does with CPUs and chipsets.

However, Apple introduced SSD options for its latest MacBook Airs using specialized components rather than conventional SSDs built to fill the same space as a conventional notebook hard drive, such as those built by Intel. That has enabled the company to further reduce weight and thickness in the Air designs.

You might like this.

Per MacRumors, sources have stated that Apple will offer the option of a black finish on its next-generation Sandy Bridge powered MacBook Air ultraportable notebooks expected to arrive in the near future.

Citing “several anonymous tips,” the site reported on Monday that Apple will will offer “at least some models” of its next MacBook Air with a black finish. That would be different from the aluminum currently found on all MacBook Air models.

“The most specific of the claims suggests that a black anodized aluminum case would be available on a top-end MacBook Air model, in much the same way as Apple once offered a high-end black MacBook on top of the standard white offerings,” the report said.

Author Eric Slivka said the site is “unable to confirm the rumors,” but given the fact that numerous tips have been received, the information was shared “for interest and discussion.”

It’s been stated that Apple is ready to build nearly 400,000 next-generation MacBook Airs this month in preparation for the anticipated launch. The new hardware is expected to sport Intel’s latest Sandy Bridge processors, as well as the new high-speed Thunderbolt port codeveloped by Apple and Intel.

The new thin-and-light MacBook Air launched in late 2010 with a new 11.6-inch model and a lower US$999 introductory price. The device was an instant hit, and made the MacBook Air one of the most popular products in the Mac lineup overnight.

Stay tuned for additional details as they become available.
