Wednesday means it's time for another Ask TUAW! For this edition we've got questions about what Macs will support Snow Leopard's forthcoming OpenCL acceleration, using Boot Camp with multiple partitions, connecting a Mac mini to HDMI, automatically importing images into iPhoto, 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.

We're back with another edition of Ask TUAW. This time around we've answering questions about how to resize windows too big for the screen, "compulsive" updating, booting from an SD card, Open GL in Snow Leopard, 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.

Steph asks:

I recently switched from an iMac to a MacBook Pro and now many of my windows are sized to big for the screen of my laptop. I can't reach the corner to resize them and clicking the "Plus" sign in the corner doesn't help. What can I do?

Fortunately, this is very easy to fix. Instead of clicking on the "Plus" sign (the green button) in the top left corner of the window you are trying to resize, Option-click it and the window will fill your new screen size instead.

John asks:

I realize there's a method for updating Mac OSX all the time and sometimes I get the window popping up saying I have updates. Should I always update immedietly when it tells me I have some?

If you purchased a new Mac or Xserve on or after June 8th, Apple just announced that you'll be able to take advantage of the Mac OS X Snow Leopard Up-To-Date Program.

Under the terms of this program, if you purchase a Mac or Xserve on or after the cutoff date, and Snow Leopard is not included in the box, you'll be eligible to receive an upgrade DVD for only US$9.95 (shipping is included in price).

The program web page is currently stating that additional information will be posted tomorrow (June 16th), and we'll be sure to keep you in the loop if any changes or additions to the program are announced.

On October 17, 1998 Apple released Mac OS 8.5, the first operating system that ran solely on Macintoshes with PowerPC processors. As far as system software upgrades go, this was the end of the line for any Mac built before the Power Macintosh 6100, introduced in March 1994. Earlier Macs ran on some variation of 680x0 processors and were supported mostly via emulation in a PowerPC environment. Emulation works, but it also slows things down. By 1998, Apple decided it just couldn't support 680X0 emulation for a number of reasons, but chiefly among them was speed.

What happened was just what you would expect. In user groups, USENET and the Internet (which was only starting to explode), apoplectic non-PowerPC Mac owners threatened class action lawsuits and the rending of garments. Of course, most Power Mac users loved the newfound speed introduced in Mac OS 8.5, thanks to code optimized for PowerPC processors and jettisoned emulation support.

It took Apple only four years to introduce the PowerPC chip and make any Mac without it obsolete. Technology moved on.

In September Apple will release Snow Leopard, which will only run on Intel based Macs, thus cutting off PowerPC support. This time it took eleven years from inception to extinction (well, three for the Intel transition), but even so I can hear the hue and cry machine cranking up. Once again, the major reason for dropping legacy support is speed. Technology has moved on.

Whenever something like this happens there is a potential for a marketing meltdown, but this time Apple is doing something brilliant. It is going to sell Snow Leopard for $29. When I saw this on the video stream of the WWDC keynote address my jaw dropped, my eyes glazed and only later did it start making sense to me. Apple first introduced Mac OS X in 2001, and excluding the free update to Mac OS X 10.1 from Mac OS X 10.0, a new version of the OS has been released roughly every 18 months, always at a price of $129. The sales pitch is always the same: with each new version, OS X gets new features and an "enhanced computing experience" which largely depended upon how much you like the new features.

Mac OS X 10.6 will be the fifth major release in eight years, and some users are complaining about feature overload. There will always be users who want four ways to do the same thing, but for others, feature-laden releases are overwhelming and the glimmer and excitement of a new OS X release has faded. What a perfect time to work under the hood, set up the core of the operating system for the future and stabilize what's already there! But of course you can't make everyone happy. I would expect a large group of users to not be mollified by a nicer QuickTime and an improvement to Stacks. In effect, where's the beef? The beef is under the hood this time.

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...

Michael Flux has posted some pictures of Snow Leopard build 10A380, and there are some interesting things worth pointing out.

The stack frame now has a attractive border between it and the shadow which looks quite nice. Also, an option for folder actions now appears in the Finder's contextual menu.

There's a cool feature in Safari that lets you create a note from any selected text. I'm also happy to see that the Image Capture app no longer looks completely out of place and matches the other apps. Also, Preview's "Contact Sheet" view is very cool. Think of a PDF's pages being displayed in a big grid.

What's very nice to note, and what I'm most looking forward to, is the list of apps that Michael describes as looking the same but operating much faster, including Address Book and Font Book. I love what Apple's doing with this update in tidying up Leopard and making it tighter, faster and more efficient. I can't wait to buy this.

John Gruber mentioned in a recent post about Apple's Snow Leopard list of Enhancements and Refinements that one of the small adjustments to Snow Leopard will be that the default gamma on displays will switch from the typical 1.8 value to 2.2, which is what is used on TVs as well as being the long-standing default gamma value in Windows.

Gamma affects the visual contrast you see on your screen, and a higher value indicates a higher level of contrast. The cost of this higher contrast is that you lose some detail on the less luminous parts of your screen.

If you're interested in seeing what this is going to look like in Snow Leopard, or switching your gamma setting now so that you're used to it ahead of time, here are the steps to do it using the Display Calibrator Assistant:

1. Head into System Preferences, and click on the Displays icon.
2. Click on the Color tab, and press the Calibrate... button.
3. On the Introduction window that opens, click Continue
4. On the next screen, "Select a target gamma", choose "2.2 Television Gamma"
5. Click Continue leaving your Target White Point set to Native (or whatever yours is set to)
6. Now name the new profile you've created, click Continue and then Done.
7. Lastly, you can now choose to switch between your default color profile, and your newly created profile with the gamma set to 2.2.

I realize this might seem terribly obvious to some users, but for others playing with color profiles is not ground they've previously covered. If you're one of those people, this tip is for you.

If you know me, then you know that I love Automator and scripting things on the Mac. I believe that Automator should be something that everyone can take advantage of, not just the select few that already know how to use it well. That's why I've been working on the TUAW Mac Automation and AppleScript series for over a year now (we're going to have more coming soon, so stay tuned).

I was watching the WWDC '09 keynote, desperately waiting to see if anything new was announced for Mac OS X 10.6 Snow Leopard in regards to automation, and specifically Automator.app. Nothing was said at the keynote, but when I looked on the newly updated Snow Leopard page on Apple's site, I was ecstatic. One of the refinements listed was that Mac OS X Services would now be a feature of Automator. Services let you use features of one application while you are inside of another. In the Automator instance, you would be able to use workflows while you are inside of any Mac OS X application that supports the use of Services.

In addition to updating Automator for Services, Apple has also added more starting points for workflows. You can now choose between a standard workflow, application, service, folder action, print plugin, iCal alarm, or an image capture plugin. We will have more information about Automator and Services in Snow Leopard when it launches in September.

It's not news. It was just less than a year ago that we initially announced that Snow Leopard would likely be Intel-only. Still, it was a report based off an initial developer's release of the software, and PowerPC users prayed that maybe it was a mistake. Maybe Apple would change its mind and toss a bone at these faithful users of Macs-gone-by.

But, the emerging reality showed that Apple has left its PowerPC days behind. In February, we reported on how GarageBand's new Learn to Play feature was Intel-only. In addition to that, not every feature in iPhoto was available to PowerPC users. During that same month, we reported that even more G4 systems were being added to Apple's vintage and obsolete lists.

Now the writing is fully on the wall for PowerPC users. The official release of tech specs for Snow Leopard indicates that it is an Intel-only release, meaning that if you do want to go past Leopard, you'll have to upgrade. There are still a lot of PowerPC users out there, and they're still very good machines... but are owners of older Macs going to be satisfied without the latest OS?

Answer our poll or let us know in the comments: what does Snow Leopard mean to PPC owners?

With all the news floating around today about the new iPhone 3G S, and the updates on the release dates of iPhone 3.0 or Snow Leopard, you might feel deprived if you didn't get to make it out to this year's WWDC. Don't fret. You can now watch the keynote stream on the Apple website and see all of the announcements from the event. Click here to go to the stream page.

You can view all of our coverage from this week on the TUAW WWDC page.

Update: You should soon be able to download the keynote as a podcast from iTunes via the Apple Keynotes feed, which can be found here [click opens iTunes].

If you have Mac servers in your business, you weren't left out of the Snow Leopard fun during the keynote earlier today. Apple also announced that Mac OS X Server 10.6, A.K.A. Snow Leopard Server, will be shipping in September. Like Snow Leopard, the server version of the OS provides 64-bit support, and many of the Apple applications have been updated to take advantage of that. For example, SMB file server performance is 2.3x faster than Leopard Server, and AFP file server performance is now 1.3x faster.

New features include:

iCal Server 2 -- This upgrade to Leopard's iCal Server now provides push notification, wireless accessibility to your calendar from any iPhone, a new web-based calendaring interface, and updates to CalDAV that now allow you to invite colleagues to meetings via email.

Podcast Producer 2 -- Podcast Producer, which was added to the server mix in Leopard, is now improved with Podcast Composer. This new feature lets you create your own workflows for automating completion and publishing of podcasts. There's also a new Setup Assistant in Server Admin that can set up Podcast Producer 2 in a manner of minutes, even if you're setting up a cluster of servers.

Wiki Server 2 -- Workgroups wishing to collaborate now have a little bit more to love from Wiki Server. The only real new feature is iPhone support; users can securely log into confidential wikis and content, and even review content and comments from the iPhone.

Mobile Access Server -- The piece that I'm probably the most excited about as an Xserve admin is Mobile Access Server. This new feature is like a custom VPN for Mac and iPhone users. As long as they're set up in the server's directory service, users can get secure, encrypted access to the server and network with very little hassle.

Mail Server -- The engine running Mail Server has been totally redesigned for much faster service, and now provides push email, vacation messages and server-side rules, and improvements to mail server clustering.

Web Server -- The biggest change to Web Server is that it can now do HTTP live video streaming. Performance is about 1.3x faster than Leopard Server's web services as well.

Client Management -- Organizations that are deploying many iPhones will love the new client management piece of Snow Leopard Server. It has an iPhone configuration utility for creating profiles that can be emailed to corporate users, thus setting up secure services in a few seconds. Administrators can now also use NetRestore to rebuild Macs over networks, based on either a custom build disk image or a standard OS X install disk.

Best of all, Snow Leopard Server will cost $499 for unlimited users (a sharp reduction from Leopard Server's price of $999 unlimited, $499 for 10 users) and should be shipping at the same time OS X 10.6 is available to the rest of us. I'd just be happy if Apple has finally fixed a lot of the issues with backing up network users to Mac OS X Server using Time Machine.

For the ultra low price of $29 (for existing Leopard users), Apple gave a deeper look into the upcoming Snow Leopard release -- slated for some time in September.

"We've built on the success of Leopard and created an even better experience for our users from installation to shutdown," said Bertrand Serlet, Apple's senior vice president of Software Engineering. "Apple engineers have made hundreds of improvements so with Snow Leopard your system is going to feel faster, more responsive and even more reliable than before."

Here's more highlights of the Snow Leopard release...

Seems like only yesterday that QuickTime was at version 7. Oh wait, that was yesterday. Among the many announcements surrounding Snow Leopard we saw a little more of QuickTime X, Apple's next-generation version of the venerable media player/technology/doohickey. While the interface has been totally overhauled, the changes are more than skin deep.

QuickTime X is a significant update. For consumers, there won't be a Pro version. Any version will allow simple editing, video/audio capture, and allow you to "publish your media to MobileMe or YouTube -- without worrying about codec formats or resolutions." We're not sure if you'll be able to save as a QuickTime movie or source file as before, but the removal of some previous limits will make QuickTime the snappy iMovie substitute it could be. Plus, QuickTime X will allow you to use any web server to stream live video over HTTP. Can't wait to see what people do with that.

In addition to the visible changes, QuickTime X looks like a fundamental rewrite of the application and its underpinnings. Support for Core Audio, Core Video and Core Animation could mean some really interesting things for the future of media playback (not that we weren't promised as much a few years ago, of course). All of this comes wrapped up in Snow Leopard, and takes full advantage of the speed-tuning tech therein.

Today, Apple announced a ship date and upgrade pricing for Mac OS X 10.6 Snow Leopard. 10.6 will debut this September as an upgrade for Mac OS X Leopard users for just $29. "We've built on the success of Leopard and created an even better experience for our users from installation to shutdown," said Bertrand Serlet, Apple's senior vice president of Software Engineering in an Apple Press Release. "Apple engineers have made hundreds of improvements so with Snow Leopard your system is going to feel faster, more responsive and even more reliable than before.

Snow Leopard features include built-in Microsoft Exchange 2007 support along with a slicker install process, faster applications, and 64-bit versions of standard applications that boost overall performance. Apple brags that "[u]sers will notice a more responsive Finder; Mail that loads messages 85 percent faster and conducts searches up to 90 percent faster; Time Machine with up to 50 percent faster initial backup; a Dock with Expose integration; a 64-bit version of Safari 4 that boosts the performance of the Nitro JavaScript engine by up to 50 percent and is resistant to crashes caused by plug-ins."

In addition to the $29 single user upgrade, a family pack upgrade will cost $49. Tiger users will pay $169 for a 10.6/iLife box set or $229 for a family pack.

All users who purchased or will purchase a new qualifying Mac between 8 June 2009 and 26 December 2009 will receive a free upgrade package and pay $9.95 for shipping and handling. You must request your up-to-date upgrade within 90 days of your original purchase.

Snow Leopard requires a minimum of 1GB RAM and runs on Intel-based Macintoshes. Full system requirements are hosted at Apple's tech specs page.

We're down to the wire -- less than 90 minutes before the WWDC Keynote ramps up, and the rumor mill has wound down to a murmur after a week of wild speculation. Want to read about how the new iPhone will singlehandedly boost your love life, bring you millions of dollars and boast a video camera, Swiss Army knife, automatic can opener and turn into a mini TARDIS? Sadly, those rumors have yet to appear. Except maybe the video camera.

Daring Fireball's John Gruber has been the focus of most of the very last-minute guessing with his thoughts of today:

• The iPhone 3G ... oh, sorry, iPhone 3GS: It'll be faster, twice the current amount of RAM, video camera, more storage ... those aren't new rumors. But, Gruber says that he's heard that the phone will also receive a name upgrade to the iPhone 3GS. The other nice piece of speculation is that the iPhone 3GS will also have a 15-20% longer battery life over the current model.
• Cheaper phones for the masses: A $99 version of the iPhone that will not have as many features as its more expensive siblings, though it could just be the existing 3G iPhone at a lower price after the new models are introduced. This isn't exactly that new of a rumor considering that The Financial Times had this one over the weekend.
• Snow Leopard pricing: Gruber believes we could see Snow Leopard priced as low as $19 considering it doesn't have any major features ... unless Apple manages to pull out something today.
• Playing with Marble: Of course, that new $129-cost "feature" could be that Snow Leopard will feature a reimaging of the OS's visual appearance. However, it's more likely that a move to "Marble" is slated for OS 10.7.
• The Holy Grail ... er Mac tablet: It's real, but not today.
