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.

The Dock's Stacks feature lets Leopard users view a folder's worth of stuff with one click. You'll either love it or hate it, use it or not. If you do use it, here's a little tip that improves it slightly (in my opinion).

When you've got a bunch of files from a Stack displayed in Grid View, it can be hard to spot the particular one you're looking for, especially if many of them look identical (such a collection of text files or word processor documents).

Luckily, there's a highlight you can switch on, that puts a whiter background around the file you're mousing over. It makes it slightly easier to ensure you click on the correct file.

The highlight appears normally if you use the arrow keys to move around a Grid, or if you type Command and the first letter of one of the files displayed. But this trick switches it on permanently, so that it is always in action whether or not you use these keyboard shortcuts.

Read on for all the commands.

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.

Think getting music from the WiFi store on your iPhone would be cool, but frustrated that they haven't implemented it yet? Justin sent along a simple little tip that makes it easy to grab all the music you want off of Myspace band pages, even without Jobs' Starbucks integration.

Lots of Myspace band pages offer little Flash-based widgets that will play music for you, but without Flash, MobileSafari won't let you at them. But with a web application like file2HD, getting at those music files is easy-- plug in the Myspace URL, choose Audio, agree to the Terms of Service, and boom, you get a list of URLs, that, like any other Quicktime-playable media online, will stream directly into the iPod's music player.

There is, of course, a catch. According to the Terms of Service for file2HD (or any other service like it, I'd imagine), you can only access your own pages. Myspace, obviously, wants you visiting their page to hear that music. Listening to it on your iPhone will definitely violate the ToS that you agree to. Not that anyone should care-- most bands put this music on their Myspace page to promote themselves, and so it's likely that they want you listening to the music no matter how you hear it. So as long as you can justify your way past that little conundrum, you're home free. Listen on (at least until the iTMS WiFi store lets you get music cleanly and legally from wherever you are).

Thanks, Justin!

Brandon sent us a great tip that I should have known was in Safari, but that I hadn't found yet. For you paranoids out there, the Safari 3 beta offers an easy way to clean up every single thing you've ever done, including the history, passwords, cookies, and even favicons and Autofill text. Under the Edit menu, there's a "Reset Safari" option which reveals a checklist that lets you hit the reset button on your browser. Firefox users like myself will notice that this was "gently lifted" from the Clear Private Data function under FF's Tools menu.

And it's not just for paranoid browsers out there-- the blogging engine here at TUAW, Blogsmith, is a great program but sometimes hiccups when the cache gets overwritten or pushed out of sync. When it does, the Reset options let me flush the cache in just a few clicks without losing any of my browser windows. If you ever run across a browser-based application that's not doing what you want, this is definitely an alternative to try before actually restarting the browser.

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.

I don't know whether it's just me, but the one thing that I've always felt was lacking from Spotlight was the ability to quickly and easily reveal the enclosing folder for search results. It was never a major problem, but on the rare occasion when I do use Spotlight, I often seem to need to see the search result's containing folder. Earlier I was looking up a rogue "mds" process which was hogging 60% of my MacBook's CPU when I came across an article on Macintouch, with this little tidbit at the end from Chong-Yee.

"Apple's "Spotlight Tips" page is good, but doesn't include the following tip I discovered. If you want to reveal a file in its enclosing folder from the drop down Spotlight results list, hold down the Command key and click the result."

This is probably something I should have discovered on my own anyway (holding down Command during any action in OS X usually reveals some kind of useful alternative action), but because the problem wasn't so annoying that I felt the need to research it (hence my accidental discovery) I never thought to try. Usually I'd click "show all", and then right click the item and press "reveal in Finder". That usually took a few seconds -- now the process takes less than a single second.

This personal example reminds me of Steve Garfield's entertaining interview with David Pogue (seriously, check out the bit at the end where David sings and plays the piano) where he talks about cool shortcuts that developers put into their work which, for whatever reason, don't make their way in the official documentation.
