Sure, we've all wanted to stop the pesky "Disk Image Verification" process that starts when you want to open that .iso, .dmg, or other disk image. While this process is a precaution against possibly installing/using corrupt files, sometimes it is completely unnecessary. To stop disk image verification forever, just open Terminal and type:
defaults write com.apple.frameworks.diskimages skip-verify TRUE
If you want verification enabled again, type the same command, replacing the "TRUE" with "FALSE." While verification is off, we recommend only using disk images from trusted sources.
