• Live Verification only works on (HFS+J) volumes. If you try to verify a non-journaled disk, Disk Utility will display this message: 'ERROR: could not freeze volume (Operation not supported).' • During a Live Verification, the Disk Utility progress indicator may stop advancing, open applications may act slow or become unresponsive, the progress pointer (it looks like a spinning pinwheel) may appear, or your computer could appear to stop responding ('freeze'). • Once you start a Live Verification, you may not be able to cancel it, depending on how far along it has progressed.
Disk image files on the Mac OS X are DMG files. They are like virtual images of disks that come with software that is downloaded from the Internet. They contain a copy of the application you downloaded and after they mount on your Desktop, you can remove the application inside by dragging and dropping it in your Applications folder. I am trying to download the trial version of Photoshop Elements 6 from the Adobe website onto my iMac. However, it keeps failing because I don't have the diskimagemounter.app. Adobe help was anything but helpful. Hopefully someone here can help me. Please describe in detail the exact actions.

Newbie questions. • You may experience some issues if you try to verify or repair any unmountable, non-startup disk. • If you see any 'Incorrect size for file temp' alerts, you can safely ignore them. Disk Utility may stop responding without displaying an error message, or stall your computer for several seconds, when trying to verify or repair some non-startup volumes that can't be unmounted. If you try to verify a volume that is not your startup disk but for some reason Disk Utility can't unmount the volume (for example, the disk may have open files), the verification will appear to start but then stop without displaying any alert message.
