We mentioned Gamesalad's plans to bring their publishing system to the iPhone earlier this year, and now they've done it: for $99 a year, they say that you'll be able to design games on their game creator development tool, and then publish them straight out to the iPhone's App Store. If you don't want to bother publishing the games yourself, you can create them and have them "viewed" through the Gamesalad Viewer (which we couldn't find on the App Store quite yet), or you can export them out as full applications and publish them as your own iPhone apps (Flutterby is in the store right now as an example of a Gamesalad Creator game).

There's also a $1999 membership service that lets you customize every aspect of your games, and provides you with direct customer support, which is supposed to be for "elite users" (like, we guess, actual game companies). And truthfully, I've developed a few apps using just Xcode, and it's not too big a deal (though I've never had to go through an actual release or worked with end users, which I'm sure is most of the battle anyway). But if the thought of using professional coding tools to develop your little game idea sends you into panic attacks, and the Gamesalad creator seems more your speed, this might be a nice viable way for you to turn your gaming idea into App Store gold.

It costs nothing to download and try out the creator, so if the idea interests you, you can work on putting a game together, and then pay later when you decide you've got something you want published on the iPhone. And hey, if you do put a game up, be sure to send a tip and let us know -- we'd love to see the end products of this process.

One of the little frustrations in my everyday use of Leopard was the way it searched in folders. When in a Finder window, there was a handy-looking search box in the upper right-hand corner. I would place the cursor, type my query, and be annoyed by the fact that OS X searched my entire Mac.

Nooo. If I wanted to search the whole thing, I would have asked to search the whole thing.

Thank goodness Snow Leopard fixes this minor workflow speed bump. Now you can choose what you'd like to use as a default: Search This Mac or Search the Current Folder. You can even say "I'll have another" by choosing to Use the Previous Search Scope.

Unfortunately the default out-of-the-box action is still set to look everywhere on your Mac. But don't worry, it's easy to change.

1. Make sure Finder is your active app (either click on the Finder icon in the dock, click the desktop or a visible Finder window, or cmd-Tab to switch to the Finder).
2. Choose Preferences in the Finder menu. Or you can just use the Command-comma key combo to invoke Preferences.
3. In Finder Preferences, click on the Advanced tab.
4. Choose your desired search scope from the drop-down menu under the heading "When performing a search."
5. Close the Preferences and enjoy a search or two.

That's it. Just one example of the many little changes in Snow Leopard that make life with the OS easier and more efficient. I hope you find what you're looking for!

Let's face it, contact management is a pain. Address Book in OS X is a good tool, but one often overlooked feature is the "Smart Group" -- a way of quickly organizing your contacts together. If you're familiar with Smart Playlists in iTunes, it's the same but with contact info.

To start a Smart Group, go to File > New Smart Group. A dialog will drop down in Address Book for you to start entering criteria for filtering. For example, you could create a group of everyone whose birthday you have in your contacts by choosing the item Birthday from the first drop-down menu item, then adding the menu item "is set." Note that you can't create a list of people with birthdays in June, which is a bummer. But the Smart Groups have a variety of ways to filter, some more useful than others and several are dependent on the data (dates vs. text, for example).

To delete a group you'll have to make a trip to the menus, as no amount of right-clicking or key pressing will do it. Delete is in the Edit menu, under Delete Group.

One more thing: the notes field in Address Book extends the power of Smart Groups just a bit. After returning from WWDC I added the business cards of people I met and added the note "wwdc" to each one. I then made a Smart Group where the Note contains 'wwdc' and now I've got an easy way to see the group of people I met at WWDC. Think of the Notes field as a loose tag field, if you like.

I've also set up my Address Book to add family members based on a list of surnames, but that may only work if you have an oddball last name like mine!

Are you tired of all of those icons from screenshots you've taken cluttering up space on your desktop? If you would like them in a different place when you snap them, here's a command to change the location.

Using the Terminal, enter the following command to change the location:

defaults write com.apple.screencapture location ~/Pictures

This snippet will change the default location of saving the screenshot to the Pictures folder. You can also set this location to any folder or volume on your Mac, just substitute ~/Pictures in this command to whatever you want. Once you've run this command, you'll need to restart the SystemUIServer (used to control certain interface elements in Mac OS X), by entering killall SystemUIServer in the Terminal.

If you don't want to use the Terminal, many of the popular Mac maintenance utilities, including OnyX (free). TinkerTool (free), and Cocktail ($14.95), will allow you to change the location of snapped screenshots.

If you're snapping a lot of screenshots, changing the location can be very useful, especially if you're on a portable Mac with limited disk space. Each screenshot can sometimes be over 1MB in size, so if you're tight on space it can be a good idea to store your screenshots elsewhere, like on an external hard drive.

There's also a handy suggestion from our own TJ Luoma: redirect your screenshots to a cached/synchronized folder, like the Pictures folder on your iDisk (if you have iDisk Sync turned on) or a folder in your Dropbox, Live Mesh or SugarSync directories for instant screenshot sharing among multiple machines.

Let's face it, the less distractions you have while driving the better, even if the government can't decide whether or not to tell you how dangerous phones + cars can be. Last week I was happy to see Penn Jillette (a magician whose work I've admired since I was too young to say the name of his current show) on Twitter proudly announce he was going to quit calling and texting in the car. Bravo!

Penn happens to sport an iPhone, and like any modern cell phone, it has "airplane mode." I'm going to show you how to set the iPhone to this "no call" mode, and explain why you probably don't have to while driving. Plus, if you absolutely must talk while driving I'll explain a helpful trick with the 3GS. You should never under any circumstances try to type while driving -- pull over, already.

To turn off your iPhone's cell radio, thus preventing distracting text messages, push messages and phone calls, go to Settings > Airplane Mode and turn the switch ON. Pretty easy, yes, I know. But unless you are going to use the iPhone's audio in your car (and there's like a zillion apps for that), you could just as easily turn off the ringer. The switch above the volume buttons on the left of the screen controls the mute for external sounds. When you arrive at your destination, check your phone for missed calls, etc.

If you have a 3GS, you can use the Apple headphones that came with it to activate Voice Control, giving you a relatively safe method of interacting with your iPhone while driving (except for a proper, Bluetooth speaker/mic or in-car solution, I guess). Plug in the headphones and put the headphone directly connected to the microphone in your ear. Press and hold the "middle" button (in-between the volume buttons) for about 3 seconds, until you hear the beeps. Voice Control is now on! You can control the iPod functions and make calls, but I recommend you try Voice Control before you start driving. Note that there are voice dialing apps for previous iPhones, but I feel having to see the screen to push even one button is an unacceptable distraction.

The New York Times and many other news outlets have reported on the unreleased government study showing that even talking on the phone increased the likelihood of having an accident -- whether you are hands-free calling or not. Driving and chatting with a disembodied voice can be distracting, apparently. So, again, the only truly safe thing to do is to switch off your cell radio entirely (Airplane mode). This won't allow you to play streaming radio stations, but it may save your life. Otherwise, use your willpower to ignore the chimes, rings and buzzes, and if you absolutely must talk or text, pull over.

Whether you're moving to another country or just visiting, chances are pretty good you're going to be bringing a lot of electronics with you. Chances are also pretty good that whatever country you're going to is going to have an electrical system with a different voltage or frequency than your home country, and probably differently-shaped outlets, too.

When traveling abroad, this vast array of voltages, frequencies, and plug types can be confusing, and whether you're packing a $200 iPod nano or a $2000 MacBook Pro, it can lead to a great deal of trepidation as well. The traveling geek's worst nightmare goes like this: you plug your very expensive, potentially irreplaceable electronics into some weird Romanian outlet, and suddenly sparks start flying. You try to unplug your precious device as quickly as you can, but the damage is done -- with a whiff of ozone, hundreds or thousands of dollars worth of equipment has just become a glorified brick.

Happily, most modern electronics shouldn't experience this issue, and that includes all recent Macs and iPod/iPhone power adapters. Here are a few dos and don'ts when it comes to international electricity.

Have you ever been playing one of your finely-tuned playlists, blissfully grooving to the music, only to connect your iPod or iPhone and lose your place? In other words, iTunes (if you've set it to automatically sync) will move your view from whatever playlist you're in to the sync window. That's handy, of course, but if you forgot which playlist you were in, it can be a pain. I have several playlists set to random, and when I try to go back, it re-shuffles the order. There are other multi-tasking issues with iTunes that largely stem from its one-window interface. If you want to browse the store and manage a playlist, for example, you're stuck doing a lot of scrolling. But iTunes isn't really one window!

If you double-click the title of a playlist, it allows you to edit the name of the playlist, right? But if you double-click the icon of a playlist (for a standard list it'll be a little blue note to the left of the title), iTunes will open an entirely new window, as seen above. You can open a bunch of these if you like and it works with TV, Movies, pretty much everything on the left side. It's much easier to drag and drop songs this way if you have a bunch of playlists. Plus, the window menu will give you quick access to whatever you opened, or you can switch through them with Exposé.

Note: yes, this has been in iTunes for a long time.

If you're switching from Windows you may be familiar with an old friend, the Task Manager. Apple provides a similar tool, with an easy way to force unruly applications to quit. I'll get to why you'd want to do this in a moment. To access Force Quit, you can either go to the Apple menu in the top left corner of your screen, and choose Force Quit... Alternately, you can press three keys at once: Command + Option + Esc.* It's sort of the Mac version of Ctrl-Alt-Delete.

Why would you want to force an application to quit? Sometimes applications get "stuck" for whatever reason and can't recover. If you notice the "rainbow wheel" spinning when you try to access the application and it just won't do anything, check the Force Quit tool and see if the name of the application is red and there's a parenthetical warning "not responding." This is your cue to use Force Quit -- just be aware that sometimes an application might not be responding, but might still be "alive." Typically what I do is go grab a cup of coffee, or stretch, and give the app 2-5 minutes to get itself together. If it is still stuck, I force quit.

For more on Force Quit, check out this Apple tips article on "Knowing When to (Force) Quit." And knowing is half the battle.

*Fixed, thanks to the handy commenters!

Here's something I know affects plenty of users out there. Have you ever pasted text in a document or email message, only to have it formatted differently than all the text around it? Irritating, right?

There's an answer, thanks to the Keyboard & Mouse pane in System Preferences. If you click the Keyboard Shortcuts tab, you can assign "Paste Without Formatting" and/or "Paste and Match Style" to Command + V for all applications. Just click the button under the list, type in the name of the appropriate menu items, and press ⌘-V in the Keyboard Shortcut box.

One note: Panic designer Neven Mrgan found that using this tip means you won't be able to paste images into iChat using Command + V. Dragging and dropping (or choosing Paste from the Edit menu) still works, though. Update: If you explicitly add ⌘-V in as a shortcut for Paste that's specific to iChat, you can restore the image paste capability without breaking the global shortcut.

Apps that don't have either of those menu items will still default to regular old "Paste" for the same key command. Paste away!

If your iPhone was connected to an Exchange server for email, contact or calendar synchronization prior to your upgrade to the 3.0 software, you may have run into the same problem that was bugging me for a day or so: the timeout on the passcode lock gets set to "Immediate," forcing you to enter the code almost every time you pick up the phone. Secure, sure, but very annoying. Going to the usual settings location to adjust the timeout shows no choices other than the insta-lock; what to do?

A thread on the Apple discussions boards points to the answer. Since the ActiveSync link to the Exchange server controls some security policies on the phone, you need to refresh those controls; the easiest way to do that, short of deleting and recreating the Exchange account, is to turn off all three sync modes and the Push setting. Once that's done, you can go back to the passcode lock screen and disable the lock or adjust the timeout. Put your sync settings back the way they were and your changes to the passcode config should remain in place.

While this is an annoying quirk, it's not all gripes and grimaces in the Exchange support department. At long last, users of Exchange calendars can send meeting invitations (hallelujah!); Exchange 2007 users can even view the reply status of attendees. Users can specify additional mail folders for sync, and Exchange 2007 users can search server-side mail from their devices.

Thanks to everyone who sent this in.

Have you ever needed more room on your screen? Or have you ever needed a way to organize all the stuff you are working on with your Mac? Mac OS 10.5, aka Leopard, debuted a feature called Spaces: a way of creating extra screens on your Mac. Think of them as virtual workspaces, where you can easily drop application windows to reduce clutter or simply focus on one thing at a time.

To activate Spaces, go to System Preferences > Exposé and Spaces > Spaces. From there you can enable from 2-16 "spaces" (virtual screens) and you can fine-tune application behaviors. For example, I have Skitch set to appear in Every Space, which simply means it'll appear in whatever space I happen to be working in when I open Skitch. Normally switching to an application will take you back to the space you left it in (you can turn this off in the preferences).

The really awesome thing about Spaces: it's like Exposé on steroids. If you're used to hitting a key and seeing all open windows, now you'll be able to hit a key and see all windows in all the Spaces you have open -- thus expanding your screen real estate considerably. Plus, you can use the two together. Hit a key to see all Spaces, then hit your Exposé key to see all the windows in every Space. You can also easily drag windows to another space either in the zoomed out view or just by pulling a window to the edge of the screen (depending on which space you wish to travel to). It's hard to explain, so watch the video to see what I mean.

Note that there are some apps (Microsoft Word 2008 in particular) that don't play well with Spaces, so your mileage may vary.

I finally updated my iPhone to 2.2.1 today, and after a reboot I got the screen that says it needs to verify or authenticate the SIM card. Unfortunately, that failed because, while I do have a SIM card in there, I do not have AT&T service -- and I had the cell radio turned off. My iPhone is never used as a phone (I don't have T-Mobile in my area, so even unlocking it would be useless). I wound up restoring the iPhone, which took a couple of hours, but apparently there's a better way.

Danny Goodman on the Apple Discussion boards posts this "2.2.1 Upgrade and SIM Error (and Solution)" tip. My advice? Always turn off Airplane Mode before applying a firmware update. The phone wants to access the radio hardware during the upgrade, it seems, and disabling the cell radio makes this impossible. Thus, I was locked out of my phone for several hours today. As luck would have it, I stumbled upon this tip about 5 minutes after I started the restore process.

Have you ever been listening your iTunes library and wondered why a song played more than one time? Duplicate songs in your library can be very annoying, and waste precious space on your hard drive. In this TUAW Tip, I'm going to show you how to get rid of duplicates using a built-in feature in iTunes.

In iTunes, click the "Music" category under the Library section from the selector on the left. You should now see all of the music items that are in your iTunes library. Now click File > Show Duplicates. Any duplicate songs that are in your library will show up, and you will be able to delete the ones that you don't want any longer. To hide the duplicate song list, click the "Show All" button at the bottom of the window (or click File > Show All). You can use this same method for Music, Videos, and TV Shows. It will also work in any playlist.

Using the built-in iTunes feature is nice, but it can be very time consuming -- especially if you have thousands of songs, videos, or TV shows. In this case, you can use an application like iDupe (which costs $8US). iDupe gives you a ton of options for deleting duplicate songs in iTunes.

Do you know another way to delete duplicate iTunes songs? Know of another application to delete duplicates? Tell us in the comments!

Remember the days when getting a ringtone up on the iPhone was about as hard as, say, fixing the economy? There were all kinds of programs you had to mess around with, and sometimes it worked and sometimes it didn't, and most of the time, it just wasn't worth the trouble. Cut ahead a year from those days of yore to right now, and look at this -- all you need to get a ringtone of almost any song you want is iTunes itself.

If you want to do anything more fancy, you'll need GarageBand (and you've got it anyway, so follow Steven's guide if you'd rather do that), but as CNET shows, iTunes will let you choose the start and stop times of a song, and converting to AAC from mp3 will let you cut it down to just those times. Pull it out of iTunes, rename the extension, drag it back into iTunes (making sure to delete the version that's already in there), and voila, custom ringtone.

Note, however, that it doesn't work for music with DRM on it, but it does work for music you rip from a CD. One favor to ask, though: don't really put Young Jeezy on your ringtone -- those 'tones are obnoxious. How about a little Miles Davis instead?

Do you find yourself constantly copying/pasting text from other applications into a new Mail message? If you do, then you'll enjoy this tip.

Instead of copying and pasting, just highlight the next you want to appear in a new Mail message. Drag and drop the text on top of the Mail icon in the Dock. A new message will be created with the text you just dropped on it in the body. Just type in a subject and address and send it off ... easy as 1, 2, 3.
