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!

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.

A reader recently contacted us with a question regarding her decision to recycle an older iMac computer. She wanted to know how she could clear/reformat the hard drive, but didn't have the disks that came with the system. So, we thought we would take a minute to tell you how you can cleanse your hard drives before getting rid of your computer. I'm going to show you how to wipe the hard drive using Target Disk Mode, since this will work even if you don't have the install disks.

Step 1: Get a FireWire Cable
Both of the Macs will need to have FireWire, which means everything between the iMac DV and the current lineup (except for the MacBook Air and unibody MacBook) is eligible. You will also need a FireWire 400 cable so you can connect one end to the old Mac, and the other end to another Mac. If you don't have one of these cables, you can easily pick up one online or at a retail store. If both of the Macs support FireWire 800, you can use one of those cables as an alternative to 400; it will be faster. If one has only a 400 port and the other has only an 800 port, a converter cable (available online for less than $10) is what you need. Once you have the FireWire cable, just simply connect the two computers together.

Step 2: Boot into Target Disk Mode on the old Mac
Shut down the old Mac that will be receiving the hard drive cleaning, and reboot it while holding down the "T" key on your keyboard. After a few moments, you should see a FireWire symbol appear on the screen -- when you see this, you are in FireWire Disk Mode (FDM). When in FDM, your old Mac's hard drive should show up on the new Mac as a connected external FireWire drive.

Step 3: Do some Disk Utility magic
Open Disk Utility.app on your new Mac (located in /Applications/Utilities), and click on your old Mac hard drive in the selection area on the left. Note that you should click on the drive, and not the partition (often called "Macintosh HD") to ensure a complete disk wipe. The disk drive will most likely have a FireWire icon to denote that it is connected as an external disk. Once you select the drive, click the Erase tab, and click Security options.

In this section of Disk Utility, you will be able to select a few different erase options that will also add security to the standard disk erase. First, lets specify a name for the drive -- in the name field type what you would like the drive to show up as when it is erased, otherwise it will default to "Untitled."

Continue reading to learn about security options and how to fully erase the hard drive on an old Mac.

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!

Are you tired of the standard background for the login window? Well, if you are running Tiger or Leopard, you can easily change this picture to anything you wish. This is handy for schools or organizations who want a static background showing off their spiffy logo.

For Leopard Users
To change the background, just replace the picture file located here:

/System/Library/CoreServices/DefaultDesktop.jpg

Be sure to keep the original file in case you want to change it back to the original picture. We suggest changing the original to "DefaultDesktopOriginal.jpg" or something similar.

For Tiger Users
Tiger users don't have it as easy. You have to replace the picture by editing a login window preference file. Open Terminal and type in the following command, replacing "path_to_picture.jpg" with the actual path to the picture you want as the background:

sudo defaults write /Library/Preferences/com.apple.loginwindow DesktopPicture 'path_to_picture.jpg'

Since this is a sudo command, you will be required to authenticate as an administrator before the command will be run. Once you enter the command and logout, you should see the changes.

Have you ever wanted to quickly verify today's date, but didn't want to open iCal? Well, you could click on the clock in the menu to get the month/day/year. However, you can also change the layout of the clock to include the extra information such as month/day/year.

To do this, open System Preferences and go to the "International" system preference pane. Once there, click on the "Formats" tab and then click the customize button in the dates section. Select "Medium" from the drop-down menu. You should see the data change in the text box below the drop-down menu. Click inside the box, select all the text (Command + A), and then copy the text (Command + C). Once you've copied the text, click cancel.

Click on the customize button in the times section. Select "Medium" from the drop-down menu. Then place the cursor just before the time and paste (Command + V) the date that you just copied. You might want to add several spaces (or some sort of separator) between the date and time. Once you are finished, click OK. The changes will now show up in the menu bar.

Update: To remove the custom formatting from the menu bar, go to System Preferences > International > Formats. Click the "Customize" button in the times section and select "Medium" from the drop-down menu. Delete the additional text that you add and click "OK." Now click the customize button under the "Times" section again and select "Short" from the drop-down menu. Click "OK," and your system should return to normal.

Do you find it annoying when you go to type in an e-mail address or hyperlink into Pages and it automatically thinks you want the text turned into a hyperlink? Well, you can easily change this setting in the preferences.

Just open Page's Preferences (Pages > Preferences, or use command + , (comma) to open preferences). Once there, select the "Auto-Correction" tab and un-check the box labeled "Automatically detect email and web addresses." Now when you start typing a link or e-mail address inside of Pages it will appear as text.

Update: Alas, it looks like I'm going to have to withdraw this one. Do not use this tip, particularly on PPC Macs. Although it worked fine in my initial testing on an Intel Mac, it's becoming clear that this doesn't work for everyone, nor does it persist after a restart. So while I don't think it's dangerous (if you tried this and it didn't work properly, just force-restart the Finder to return things to normal), it is not actually a good solution. See our earlier Ask TUAW post for other, more permanent ways of doing this.

On an older Ask TUAW we were asked how to add the Trash to the Finder sidebar. I pointed to several different solutions to this, but just recently reader DG left a comment on that post with far and away the most elegant solution. Basically, show the Trash folder in the Finder by clicking on the Trash can in the Dock. Next hit ?-i to reveal the "Trash Info" window (right). Click on the triangle to reveal the Preview if it's not already visible and then drag the preview icon onto the Finder sidebar and drop it.

This will place the Trash in the sidebar with the proper icon and you can now drag and drop files to the Trash from the Finder. Not only that, the icon will even animate to show whether the trash is empty or not (though it may take a few moments to refresh your Finder window so you can see it).

Thanks, DG!

This whole 'electronic mail' really seems to have taken off with the internets, and we need to rely on it for an increasing amount of communication with email lists, coworkers, friends and more. While many Mail.app users have at least some sort of Rules system for filing messages into folders (or tagging them with Scott Morrison's spectacular MailTags plugin), I have recently been getting cozy with a lesser-known feature that can save a lot of time with hopping between folders. Under Mail.app's File menu is a New Viewer Window option (opt-cmd-n) that opens - drum roll please - a second window in which you can browse through your messages. This is particularly useful if you have a folder (or perhaps a Smart Folder) which you keep checking throughout the day; this way, you can simply keep one viewer open to your inbox (or whatever default location that suits you), with the second viewer set on that other folder. Go up to View > Hide Mailboxes (cmd-shift-m) for either window to give you some extra room to stretch out those From or Subject headings, and you just took another step up the ladder of email zen. Finally: have no fear if you need to quit Mail or restart - Mail remembers your multi-viewer setup and will put everything right back where it belongs the next time your get your email on.

I don't know about you but my iTunes source list gets crowded. Sometimes I just need a little more space for my list. Command-G gives me that space.

Its menu equivalents (View -> Show Artwork and View -> Hide Artwork) aren't exactly hidden features menu-wise but this option isn't as widely known or as widely used as it could be. It's a simple but convenient arrow to add to your arsenal. And, speaking of arrows, did you know that you could click the top bar in the Artwork display to toggle between displaying the Album art for your currently-playing item and your currently-selected item?

This isn't the most advanced tip in the book, but I found the trick darn handy last night while performing some badly needed library cleanup. In iTunes, you can open a second window for almost any item in your sources list on the left - the iTunes Store, a playlist or - interestingly - even a folder of playlists. While your library items such as Music, Movies and TV Shows are unfortunately exempt from this convenience, you can simply double-click any of these items to open them in their own window, minus a source list of their own. This is great for having easy access to playing music in one window while you work in another, perhaps cleaning up files, like I was, shopping at the store, or building a new playlist.

I just recently plunked down some of my sweet, sweet blogging money for a 24 inch Dell monitor (check out my setup) which I am loving. Setting it up with my MacBook running OS X 10.4.8 was very easy (as long as you have one of these). There are a few things that did get me, which I thought I would point out for you readers out there.

Above you see the Arrangement section from the Display preference pane in System Preferences (note that each display will popup its own Display pref pane, but only the main display will have the Arrangement option). This is where you can do a few things:

1. Arrange the displays by dragging the boxes that represent them around
2. Move the Dock and the menu bar to whichever monitor you want to use as you main monitor (as you can see I'm using the 24 incher as my main display)
3. Mirror the output on each display

This is where you should first go when you have multiple monitors, however, the fun doesn't end there.

Yesterday I wanted to do something simple with my MacBook Pro: burn a CD. Nothing fancy, I just had a 200 meg file that I needed to give someone and there wasn't a USB drive to be found, so a CD it was. I inserted my blank CD into my MacBook Pro and nothing happened.

I thought, perhaps, I had a bum CD so I tried a few more (5 to be exact). Each time I got the same result: nothing. I double checked my prefs to make sure I had 'Ask me what to do,' when inserting a blank CD, and I did.

What the heck was going on?

I was running Parallels, and it was being helpful by taking over the CD burner of my Mac, just in case I wanted to burn a CD from Windows. That's why it wasn't showing up in OS X! Luckily, this is a simple thing to fix. If you go to the lower right hand corner of your Parallels window you'll see a little CD icon. Click on it and the menu pictured at the top of this post comes up. Click 'Disconnect.' Boom, OS X sees your blank CD and asks for instructions.

TUAW-lover Andrew accidentally discovered that if you select a file in the Finder and press Apple + Shift + B (aka Command+Shift+B), it brings up the Bluetooth File Exchange application and prompts you for which device you want to send the selected file(s) to.

I love keyboard shortcuts and I know an awful lot of them but this is one that I either never knew or once knew but quickly forgot. Incredibly handy!

Thanks, Andrew!

As I was working on an AppleScript-related post this morning, I couldn't seem to find any TUAW Tips in our vast archives that explained how to enable that AppleScript menubar item (pictured) that is mentioned so often in Mac software circles. This, of course, called for just such a tip.

So: the AppleScript menubar item. It's a very handy tool for accessing all those AppleScripts you hear about that automate this or toggle that. As long as you save those scripts in ~/Library/Scripts (where ~ is your Home folder), they'll appear in this AppleScript menu - once you've enabled it. I personally think this menu item should be included in the default set of every Mac, but I'd wager that Apple sees this as a little too nerdy of a feature to drop on brand new users. Fair enough.

To enable this menu (nerd) in Tiger, go to /Applications/Applescript and open the AppleScript Utility. It offers a few options for handling AppleScripts, including turning on this menu and the order in which the menu displays scripts from both the default system level /Library/Scripts (in your main hard drive) and your personal ~/Library/Scripts folder. If you're on 10.3 (Panther), I *think* you have an /Applications/AppleScript folder, but instead of a full-blown AppleScript Utility app, it's an AppleScript called 'Install Menu' or something similar. Back on Tiger in the AppleScript Utility - you don't worry about the GUI Scripting option unless you come across a script that specifically needs it, though I don't think enabling this for simplicity's sake can harm anything either.

If this process went according to plan, you should now have your very own AppleScript menubar item like I have in the screenshot here. clicking it will offer a simple menu of all the scripts you have between the two directories you chose to display. As long as you enabled your personal Home script directory, any scripts you save there should appear in this menu immediately after saving, ready to carry out your bidding.

With that said, why not check out some of our past AppleScript posts, such as one of my personal favorites: an AppleScript from Fraser Speirs that opens iSync, syncs all your devices (such as a phone or PDA), then quits iSync. If you use an application launcher such as Quicksilver, you can tie handy scripts like these to Triggers (system-wide keyboard shortcuts) for even more convenience.
