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.

Watch Out, QuickTime

Send Article to a Friend

Apple pushers who have enjoyed a few months of uninterrupted multimedia advantage thanks to QuickTime are now a bit more concerned about what the other side has been up to. IBM reps are now showing stunning full-screen, full-motion video and sound on the PS/2 Ultimedia Model M57 SLC... and they are understandably enthusiastic about what they're showing.

The multimedia-oriented workstation is designed around a custom 386 SLC processor, essentially an enhanced 20 MHz 386 SX. It includes a color touch-sensitive display, CD-ROM drive, and high-quality audio, as well as IBM's XGA graphics standard. An upcoming enhancement will be a 40 MHz 486 CPU upgrade for the existing machine.

What impressed me at a recent computer show at which both IBM and Apple were showing multimedia solutions was that, while Apple's QuickTime technology is capable of showing full-motion video on a fast machine in a small window, IBM's technology can actually fill the screen with VCR-quality 30-frame-per-second video for several minutes at a stretch, reading the video and sound from the hard disk and decompressing on the fly.

This isn't to say that QuickTime is not a stunning technology; it is. It has a tremendous potential for providing multimedia at all levels, from the casual user on an LC II to the power user on a Quadra 950. My point is simply that Apple can't rest on its QuickTime laurels. The technology must move forward, because IBM's Ultimedia technology is at QuickTime's heels.
