Terminal Tip: Stop disk image verification


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.
