Copy Disk Image as Folder

When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.

QuickTime 7.4 Improves Security, but Not Enough

Apple updated its media workhorse QuickTime to version 7.4 last week, fixing bugs and adding support for new iTunes features such as downloadable movie rentals. But the more important news is that this version squashes a handful of security holes that could allow remote attacks. However, a serious vulnerability discovered shortly before Macworld Expo demonstrates that Apple's engineers need to remain hard at work.

The QuickTime 7.4 update is available for Leopard (a 55 MB download), Tiger (a 51 MB download), Panther (a 50 MB download), and Windows (both XP and Vista, a 22 MB download).

The most recent exploit, not addressed in QuickTime 7.4, takes advantage of a hole in QuickTime's RTSP (Real Time Streaming Protocol) that could open a computer to a denial-of-service attack or possible remote code execution. (RTSP is not a new target; see "Protect Yourself from the QuickTime RTSP Vulnerability," 2007-09-07.) Because QuickTime is the underlying technology of iTunes, Macs and Windows computers running QuickTime are vulnerable. Anyone who uses iTunes or owns an iPod should update.
