Sometimes applications can install extras in the form of System Preference panes. However, when you remove the app from your Mac, you might be left with extraneous System Preference panes.
To uninstall System Preference panes, just right-click (or control + click if you have a one button mouse) on the preference pane icon and select "remove x preference pane."
When you click "remove," the preference pane will be instantly moved to the OS X Trash can where you can completely remove it from your system by emptying the trash. Please note that this will only work on System Preference panes located in the "Other" section of System Preferences.
OS X's built-in dictionary has naughty words. Who knew? The following gallery will walk you through the steps it takes to censor your dictionary and prevent innocent young 'uns from looking up the proper meanings of these words. You'll need the Property List Editor, which is available as part of Apple's free Developer Tools.

Update: Parental Controls are a built-in but optional feature of OS X Tiger. They will be an even bigger built-in but optional feature of OS X Leopard. Those readers who feel that the existence of these controls are disturbing in and of themselves may want to take their concerns directly to Apple, who has built and implemented them in their operating system. Otherwise, non-native English speakers please take note that the post was written in a light hearted tone.
JHymn users might remember that iTunes 6 broke the DRM-stripping tool, and it seems that Apple's done a good job of keeping FairPlay locked down - until someone cooked up QTFairUse6 for Windows. Yes, it's a Windows app, but it can apparently strip purchases from iTMS version 6.0.4 and above of their constraining DRM. QTFairUse6 isn't pretty either - it's a python script that involves some tinkering, but this might be good news to those who believe that if you love something, you should set it free.
We're not sure how a one-sentence support document made it into Apple's support knowledgebase, but this strange doc somehow snuck past the velvet rope. It simply states: "There is no way to remove workout data from the nikeplus website", with a 'stay tuned for more info' bit at the end to finish off what is probably the shortest support document we have ever seen.
Getting to the topic, however: it seems just a bit strange that there is no way to remove workout information from this supposedly revolutionary new service/iPod accessory. It's not like we're suddenly terrified about Nike's trampling of user privacy, but we wouldn't be surprised if a few tin foil hat fashion aficionados raised at least some sort of a flag over this.
Hot on the heels of brining Universal status to their Application Enhancer, Unsanity has released UB versions of ClearDock (free) and Menu Master ($10). ClearDock, as you might glean from the name, is a one-trick pony that can strip the dock of its transparent background or allow you to adjust the background and the application triangle color to your liking. Menu Master is a slick utility for assigning, removing and rearranging shortcuts for menu items in any Mac OS X application. It also has a Menu Accelerator feature which allows you to "access menu items by name without using the mouse". Both applications have received feature additions and improvements, as well as bug fixes along with their UB updates.
ClearDock again is free, while Menu Master has a demo available, and a license will run you $10. Both require the previously mentioned Application Enhancer in order to work their magic on your Mac.
If you've ever
installed an app that can take advantage of .Mac syncing services and then stopped using it or removed it for one
reason or another, you might have noticed that its listing in the .Mac System Preferences pane still lingers. This
could be a nuisance to neat-freaks, but it could also cause complications in some cases.
Fortunately, a post
at macosxhints has done some digging into the matter and revealed a few clues to cleaning up the mess. It turns out that
Panic, makers of Transmit, offer a Terminal tip for removing
Transmit from the .Mac sync services list. This inspired the macosxhints poster to do some digging to see about other
services, so check out their
post if you're looking to do some .Mac sync services spring cleaning.
If, for one reason or another, you're interested in stripping all the album art from every track on your iPod, I've
found an applescript over at Doug's Applescripts for iTunes that's right up your alley. While you
might be able to spend a bit more time to complete this same process manually, you'll tie up iTunes and your iPod until
it finishes. The beauty of this script is that it can work in the background, allowing you to still use iTunes.
Now on the other side of the fence, Restore iPod Album Art might just be
for those of you who are suddenly panicking and need all that artwork back on the iPod. This one requires you to select
tracks on the iPod in iTunes, in which case the script will attempt to find the corresponding track in the library to
copy the album art from. I haven't gone through the readme, but Doug's listing says it's a must for using this script.
