Disable DMG Verification in El Capitan GM

[jer2eydevil88]

Apple took it upon themselves to break the Disk Utility in every conceivable manner. Including the preferences section that has allowed me to disable verifying the checksum of every DMG file I open. It's a pet peeve of mine to have to wait for that to complete before it opens a DMG file for an installer.

Can anyone tell me an alternative way to disable it? My Google Fu is weak on this one.

Damn, didn't even know you could do this!

At least to me, it is really starting to look like Apple's only offer to the public is going to be a glued together case with all soldered components and few if any software configuration options.
Amazing how attitudes change once you become "King of the Hill"

Sorry for the thread hi-jack.

Have you tried this?

sudo defaults write com.apple.frameworks.diskimages skip-verify true

Have you tried this?

sudo defaults write com.apple.frameworks.diskimages skip-verify true

Seems to work, but you don’t need to use sudo for this.

sudo defaults write com.apple.frameworks.diskimages skip-verify true

This worked for me! Thank you!

what i miss...i had a hack a few years ago that, when i sent a dmg to the trash, ejected the disk image automatically. anyone know how to do that? always seemed like an unnecessary extra step...

I just tried this : sudo defaults write com.apple.frameworks.diskimages skip-verify true

But get a new error: no mountable file systems? Is there any trick to fix the second error?

Cheers

This error only occurred after you changed the setting? This normally suggests that something is wrong with the DMG file.

By the way, the correct command is:

defaults write com.apple.frameworks.diskimages skip-verify -bool true

As of OS X 10.11.3 this fix no longer seems to work. The disk verification is no longer disabled and re-applying it doesn't have the same effect.

I ran into this problem with Sibelius, but I found out another workaround.

If you Navigate to System/Library/CoreServices and then launch the Installer app, it will then ask you to find and open a .pkg. Navigate to where you have your disk image saved, and select it. It'll bypass the verify and go straight to installing.

Will that stop verifying all apps ( that aren't from the store or verified) or just the one that I have selected ?

Thank you this worked perfect!
