Sometimes you have to mount a whole lot of disk images (like a script that fires up 9,999 and proceeds to sing the bottles of beer on the wall song but instead transposes those lyrics with “disks images to verify” and we can all understand how excruciating it would be to get down to 0) and just don’t want the Mac to verify each one. To disable that, send skip-verify key with a value of true(so a Boole) into com.apple.frameworks.diskimages as follows:
defaults write com.apple.frameworks.diskimages skip-verify -bool true
Or course, interacting with corrupt objects is bad if any corruption occurs so run it again with a false to disable that unholy of operations which was just perfumed after the project:
defaults write com.apple.frameworks.diskimages skip-verify -bool false
