Our sharp-eyed iPhone goddess, Erica Sadun, alerted us to the fact that there's a small, but potentially important, update that has just shown up in Software Update.

Performance Update 1.0 "addresses intermittent hard drive-related stalls reported by a small number of customers." It may not show up for you, unless you have one of the following Macs:

MacBook Air (Mid 2009), MacBook Pro (17-inch, Mid 2009), MacBook Pro (13-inch, Mid 2009), MacBook Pro (15-inch, Mid 2009), MacBook Pro (15-inch, 2.53GHz, Mid 2009), iMac (20-inch, Mid 2009), MacBook Pro (17-inch, Early 2009), MacBook (13-inch, Early 2009), MacBook (13-inch, Mid 2009), MacBook (13-inch, Aluminum, Late 2008), MacBook Air (Late 2008), MacBook Pro (15-inch, Late 2008), iMac (24-inch, Early 2009), iMac (20-inch, Early 2009), Mac mini (Early 2009)

If you own one of these models, be sure to load the update at your earliest convenience, especially if you have experienced the problem described in the update notes.

Thanks to Erica and to Joachim Bean, who provided the link to the Apple KB article.

quirky is a design firm with a difference. Rather than pay a brain trust to sit around and think up product ideas, they let average Anns and Andys submit designs that are then refined and named by a community of site visitors. When designs are ready for production, quirky sets a threshold number of units to be sold to be profitable, and once that number of orders comes in, they send the design off for manufacturing.

Plato said "...the true creator is necessity, who is the mother of our invention." In this case quirky community member Jeff Scholen was driven not only by the need to neatly wrap up the thin power cable and thick AC line going into his Apple MagSafe Power Adapter, but also keep the transformer "box" off of the floor or desk and give it a way to stay cool.

In less than 24 hours, the design was finalized through input from Apple fans worldwide and the PowerCurl (US$9.99) was ready to roll. It comes in "quirky orange" only, but has two sizes to match the 60W and 85W MagSafe Power Adapters.

The quirky community has also come up with a case design for the new iPod nano that not only protects that shiny finish, but acts as a stand and video handgrip as well. The Kickster (US$14.35) is awaiting your commitment to purchase before it moves into production.

Up to this point in time, if you wanted to "sign" an electronic document (other than a secure PDF), you either had to scan your signature with a scanner and import the resulting graphic into your document, or purchase a digitizing tablet. Ten One Design, the same folks who brought us the Pogo Sketch stylus, have come up with a way for anyone with Snow Leopard and a MacBook that supports multi-touch gestures to sign documents.

Autograph (US$6.95) is a signature capture application that works with your MacBook and a finger or stylus to make signing your name a snap. If you don't know if your MacBook will work with Autograph, you can download a trial copy that adds a watermark to the signature just to try it out.

To add your John Hancock to an email or document when Autograph is running (I have it set up to launch at startup), you can either select the menu bar icon or press control-option-A, and then a semi-transparent gray window appears. Using your finger or a stylus on your trackpad like a pen, you can write your name or draw a little picture. Pressing return embeds the signature or sketch into your document.

Autograph works great! I was able to use it in Mail, Word, Keynote, and Pages, and I'm assuming that it will work fine in any Mac application that lets you paste in a graphic. I know I'll be using this handy little program to add a personal touch to my documents. The short silent video below demonstrates Autograph in action.

If you joined us Friday night for the Mac OS X 10.6 Snow Leopard liveblog, you probably saw me say that I didn't have many issues with the upgrade. That's an understatement -- I think Snow Leopard is one of the smoothest upgrades I've ever performed with any operating system. You've probably already read the reports of fellow bloggers David Winograd and Mel Martin, which noted many similar findings.

During a four hour period after the delivery of my 5-install Family Pack by FedEx, I upgraded three Macs. The experience with each of them was slightly different, which is something you'd expect since all three are completely different models, but in each case the end result was essentially the same. All had about 10 - 15 GB more hard drive space than when I began, all were more "snappy" in terms of response, and the display looked crisper.

After surprising the FedEx delivery person with my HD video camera (yes, there's going to be an unboxing video coming later this weekend), I ripped open the box, pulled out the Snow Leopard box, pulled off the plastic, and then got the disk ready to go. I had done a final Time Machine backup of my MacBook Air just to make sure I had captured the last changes made on documents, so I plugged in the MBA's external SuperDrive and popped in the disk. I'm not exactly sure what I did after starting up the installer, but on the MacBook Air, I was asked to reboot the machine and then the installation began.

Welcome back to Ask TUAW, our weekly Mac troubleshooting Q&A column. This week we've got questions about syncing notes, iLife '09, iTunes downloads, the importance of keychains and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.

Scott asks

When I sync my iphone (3.0.1) with my Mac (10.5.8) and have "sync notes" checked in iTunes, I cannot find my notes synced anywhere in Mail.app - including under "Notes"...what am I missing?

To sync 'Notes' first make sure you have your iPhone connected to your Mac with iTunes open. Then, be sure to have "sync notes" checked in iTunes. Also, be sure to check "Sync Notes" in the MobleMe Sync options in System Preferences.

Then, sync your iPhone as normal. After that, check in Apple's Mail program under "Reminders" to see if the notes appear. You need to click on the little triangle to show the contents of Reminders. If they don't appear, close Mail and open it again. Also, restart your iPhone completely before trying another sync.

Also, keep in mind Notes sync works only via USB and not over the air. If you are not seeing notes appear, be sure you sync your iPhone via USB with your Mac or they won't appear at all. If the notes still don't appear in Apple Mail, it might be time to give a call to Apple tech support because at that point the problem may be something larger than the scope of what this column can answer.

Evan asks

I bought a new MacBook Pro last month, which came installed with Leopard and iLife '09. My purchase was within Apple's "Up-to-Date" program timeline, so I was able to order a copy of Snow Leopard for $9.95. I know Snow Leopard doesn't come with iLife '09 but considering my new computer already comes with iLife '09, I'm not going to have to re-buy iLife, am I?

Yes, it's a lot of storage -- but the drive's form factor won't fit into any currently available Mac laptop. (Note the update at the end of this post)

I was pretty excited when the Western Digital news release hit my inbox. The new drives, the industry's first in that size for portables, have pretty good specs and capacious storage space. The problem really is the size. With Apple in the business of providing slim notebooks, the drive is just too tall (12.5mm) to make it into any Apple portable, which maxes out at a drive size of 9.5mm.

The drive will be available in a USB enclosure, and WD is also offering a 750 GB version of the drive as well. The 1 TB drive lists for US$250, while the 750 GB drive is $189. Those prices are for the drive alone. Mounted in a USB enclosure the 1 TB drive sells for $300.

Currently the largest 3rd party drives you can get in current Mac laptops max out at 500 GB.

The Mac Mini may be able to house the new drive, but it would be a pretty tight fit, and according to our Steven Sande, may require the removal of the SuperDrive.

Update: We've had a variety of responses to this post, with different ideas about which, if any laptops could take this new high capacity drive. I thought the quickest and best approach would be to try the experts at Other World Computing, who make a living selling replacement hard drives for Mac Desktops and portables. The tech there told me that the last generation 17" MacBook Pro can take the 12.5mm drive, but that the 15" model can't. He also said none of the unibody MacBook Pro models can take a drive of that size. I'm sure some won't accept this information either, but these were the most expert opinions we could find since Western Digital wasn't sure and Apple doesn't generally comment on such things. Since the drives are just shipping, we'll wait for some real world experience and report back. Thanks to all who commented.

Since Apple made the design decision to forgo glare-free screens on MacBooks, iMacs, and Cinema Displays, a common problem for lots of users is reflection of light off of displays. It seems to be particularly bad if you sit with your back to a window, and it can cause both figurative and literal headaches.

RadTech has come out with some cool products for Macs over the years. For example, I've owned at least one of their ScreenSavrz "LCD Display protection, cleaning, and refinishing systems" for each MacBook I've had. The company is always in touch with the pulse of the Mac community, so it didn't entirely surprise me when they recently started selling ClearCal Anti-Glare films for MacBook, MacBook Pro, 24" iMac, and the 24" Cinema Display.

ClearCal is similar to the films you can get for iPhone and iPod touch screens, but in addition to protecting your screen, it also provides a solution for those pesky reflections. As you can see in the marketing shot to the right, it appears to do a decent job of making your Mac screen anti-glare. You can even remove the ClearCal a few times, wash it, and re-install it.

RadTech has an installation video if you're interested in seeing how easy or difficult it is to apply the ClearCal film to your display. Pricing starts at US$19.95 and peaks at US$25.95 for the 24" iMac and CInema Display. As soon as I replace my old iMac with a new 24", I'm installing a ClearCal so I can see more of my screen and less of the glare from the picture window behind me.

Mac Life and Gizmodo are both reporting that Snow Leopard will add multi-touch gestures to all older MacBooks and MacBook Pros. This has gotten a lot of people's hopes up that three- and four-finger multi-touch gestures will be back-ported to all Apple portables that previously did not have them.

Unfortunately, this is incorrect. Apples own information on Snow Leopard's enhancements reads, "All Mac notebooks with Multi-Touch trackpads now support three- and four-finger gestures." (emphasis added)

This raises the question, what's the difference between a multi-touch trackpad and a regular one, and which models have it?

The multi-touch trackpad was introduced with the first MacBook Air in early 2008. Not only does it allow two-finger scrolling like older models, it also allows advanced three-finger gestures like swiping to go back in Safari.

One month later, the early 2008 MacBook Pro received the same trackpad, with the same gestures. The multi-touch trackpad gains this new functionality because it has an embedded controller chip, identical to the one in the iPhone and iPod Touch, which allows advanced input from more than two fingers at once.

Later, the unibody MacBooks and MacBook Pros debuted with multi-touch trackpads, but also introduced new four-finger gestures, which will not be officially supported in the older MacBook Airs and MacBook Pros until Snow Leopard's release.

The original MacBook Air and early 2008 MacBook Pro are the only machines which will gain additional gestures via Snow Leopard. The only reason these notebook models are able to gain these gestures via software updates, while earlier MacBook Pros and all plastic MacBooks are not, is because they possess the multi-touch controller chip in their trackpads.

Just to break it down, this is a list of the only, and I mean only, notebooks that support multi-touch gestures, either now or after Snow Leopard:

MacBook Air (all models)
Early 2008 MacBook Pro
Late 2008 17" MacBook Pro
Unibody MacBook (all models)
Unibody MacBook Pro (all models)

If you have a MacBook Pro manufactured before early 2008 or any plastic MacBook, then Snow Leopard or not, multi-touch isn't coming your way...

Well, we're still not sure our iPhones are safe to use, and now comes word from Australia that our brand spanking new glossy screens might be hurting us as well, through bad ergonomics.

An HR advisory from Queensland University of Technology suggests that:

"Reflections and glare on high gloss monitor screens and their relation to the angle of the monitor screen, could cause the operator to adopt awkward postures when viewing the monitor screen and using related equipment. These reflections on the screen can be from internal and external sources such as the overhead lighting and/or position of windows.

Awkward postures adopted by the operator may in turn lead to an injury."

Of course Apple has moved to high gloss screens on every laptop except the 17" MacBook Pro, and the matte screen option on that laptop costs an extra fifty bucks. The iMacs are also only available with glossy screens.

Of course there are other health hazards associated with having Apple equipment, such as a tendency to have panic attacks or heart palpitations when you learn you can't update your iPhone cheaply through AT&T. At any rate, there is one advantage to those glossy screens. You'll be able to clearly see your pained face as you try to stretch into position to avoid those reflections on those mirror-like screens. So there.

It's one of the most overlooked product refreshes of the day, but the MacBook Air still deserves some credit. Not only did the Air get a drastic price drop (specifically with the SSD model), but it also gained a few specs. The base MacBook Air now starts at $1499US with a 1.86 Ghz Intel Core 2 Duo processor, 2GB of RAM, 120GB SATA drive (runs at 4200 rpm), and NVIDIA GeForce 9400M graphics card. The second model, which adds a 2.13 Ghz Core 2 Duo processor and 128GB SSD drive will only run you $1799US. That's a huge difference considering the last SSD model cost $2499 -- a difference of $700!

It is also worth noting that the MBAir now comes with a USB Ethernet Adapter in the box. You can also choose a keyboard format in either: English, Western Spanish, French, or Japanese. If you have been wanting a MacBook Air, but let the price hold you back, then there's no reason for you to complain any longer.

You can see all of the specs on the new MacBook Air models by visiting either the product page or the Apple online store.

I swear, getting old is not a lot of fun.

Last night, I taught a class in data security for home and small business users at our local community college. There were a lot of good questions from the community education program students, so the class ended quite late and I was still answering questions as I walked out the door.

This morning, I went to grab my MacBook Air out of my laptop bag and literally grabbed air instead. In my haste to get out of the classroom and head home, I had packed everything but the laptop. Fortunately, the classroom was locked and few classes are scheduled for early morning, so I called the campus police and had them rescue the MBA for me. Problem solved!

After actually losing an iPhone 3G a few months ago, I wrote a post about what to do to prevent data loss and identity theft when lose your iPhone, and included a few tips on how to hopefully keep yourself from losing the phone in the first place. In this post, I'll talk about the things that I do (or can do) to keep my MacBook Air and my data safe, even when my mind conspires against me to try to lose the computer.

It was just a few days ago we were talking about hacked MagSafe connectors, and now a lawsuit seeking class action status claims the innovative connectors are a fire hazard and a risk to life, limb, and property.

As an example, here's a link to some Flickr images of what is claimed is a melted MagSafe connector.

The complaint, filed last week in San Jose, California says that eventually the cord will fray from heat or wear, with a resulting danger of fire and injury. The suit, filed by plaintiffs Tim Broad, Naotaka Kitagawa and Jesse Reisman says Apple is aware of the problem and has done nothing about it.

The suit also claims when people demonstrate the problem to Apple, the company suggests they buy another $80.00US cable. Actually, we reported in August that Apple was replacing damaged or worn cables if they were not subject to abuse.

Apple has not commented on the lawsuit. It will be interesting to watch this one wind through the courts.

The power connector was introduced at Macworld in January, 2006. It has not always received positive reviews, even at the Apple Store.

Consumer Reports continues to shower praise on all things Apple it seems. In a report in the June issue, the Magazine says Apple won the top three places in the 13 inch laptop derby. The unibody MacBook was in first place, followed by the MacBook Air, with the white plastic MacBook in a solid third place.

CR also named the 15-inch MacBook Pro as top laptop in the 14- to 16-inch group, and the 17-inch MacBook Pro walked off with the honors in the 17- to 18-inch category. The HP Pavilion publicized in the first Laptop Hunters ad from Microsoft came in 4th in the category behind Dell and Lenovo laptops. The Sony VAIO FW370 that was the star of the 3rd Microsoft ad came in 5th in the 14- to 16-inch category.

Apple also took the honors for best in tech support.

This won't bring smiles to the folks in Redmond, who are going all out to convince people that Apple computers are not a good value. It should be noted that none of the Apple laptops were rated a best buy, but they all scored the highest in each category and were recommended by the magazine. Of course Apple has repeatedly said they are not trying to win on price, but on quality, and Consumer Reports seems to accept that as the case.

I generally don't put a lot of stock in CR for some of its testing, but these high ratings for Apple laptops are just one of a continuing chorus of approval from the press and generally happy Mac owners.

In what looks like a first for the Mac laptop line, support of MacBook and MacBook Pro owners everywhere, a 3rd party is offering external battery packs for MacBook, MacBook Pro and MacBook air models.

The batteries, from Sanho in California, are available in 4 different capacities, 60Wh, 100Wh, 150Wh and 222Wh, giving a computer like the MacBook up to 32 hours of battery life. The company is also offering a car charger. These items are all available for pre-order and will ship later this month. Prices are $149.95US (car charger), $199.95 (60-watt-hour battery), $299.95 (100Wh), $399.95 (150Wh) and $499.95 (222Wh). The batteries also come with a USB power port so you can charge an iPhone at the same time or separately.

The first thing I thought of when I saw this announcement was how the company was able to offer a charger with a MagSafe adapter, because that design is protected by Apple patents. I checked with the company president, Daniel Chin, and he told me: "What we did is obtain the MagSafe connector and cable from the original MacBook AC adapter, remove the adapter and splice in our own charger plug, which interfaces with our battery and car charger products. Since we are using the original Apple MagSafe plug and did not modify the actual plug (which the patent in question covers) in any way, we are still respecting Apple's IP and in no way infringing upon their patent."

That might or might not satisfy Apple, but it did allow the company to offer these chargers which are likely to be highly desired by some customers. At the very least, I'm surprised Apple has not offered a car charger for laptops. I can think of many times such an adapter would have been handy.

Update: Several commenters have pointed out the QuickerTek and MikeGyver power solutions for the MBP line, which predate the Sanho offering and use the same approach of sacrificing a MagSafe adapter to provide the plug connector. Apple's Airline adaptor, while electrically similar to a car adapter, is not recommended for automotive use (some have tried it with success, your mileage may vary). Lastly, you can of course use a DC inverter for in-car charging, but please be careful not to obstruct vents or leave the device plugged in and unattended... they can get very hot while in use. Happy motoring!

I have a MacBook Air. Although I can get about 5 hours of mobile use out of it by dimming the screen, turning off all wireless, and only running one app at a time, there are times I'd love to be able to stay unplugged for much longer. I could always get a solar charger, but that won't work well when it's dark out.

QuickerTek has announced the MacBook Air External Battery, a US$350 external box designed to let you run your MBA for up to 16 hours before plugging in. It's relatively small (7" x 3.5" x 1" -- 17.8 cm x 8.9 cm x 2.5 cm) and adds 1.2 pounds to the weight you'll have to lug around.

In order to connect the external battery to your MacBook Air, you'll either have to send your existing MagSafe cable in to be converted for use (US$25) or buy a modified cable from QuickerTek (US$100). The final bill for the MacBook Air External Battery and the cable is almost as pricey as that solar-powered charger, but it's going to give your MacBook Air much longer battery life. Now if QuickerTek could just come out with a battery to let me play Monopoly (click opens iTunes) on my iPhone for 10 hours straight...
