Now that's an iMac!

Good eye there, scout. There are a few ways to update that icon. First the tricky way: Replace the file imac.icns. Find it by navigating to /System/Library/CoreServices, then Control-click CoreTypes.bundle and select Show Package Contents. In the resulting window, dig into Contents/Resources and replace iMac.icns (an administrator password is required), then restart your Mac or log out and log back in to see the results. Finding ICNS files is the real trick; we found the sexy one in the screenshot, and tons more, at Jonas Rask Design (free, www.jonas.seph.ws/portfolio/portfolio.html). If you want a nearly endless supply of icons, try CandyBar ($12.95, www.panic.com), which lets you easily change any or all of your system icons. Cooler yet, you can download oodles of free (free for personal use, anyway) CandyBar-friendly icon sets at the Iconfactory (www.iconfactory.com).
