Disable Dmg Verification Sierra
If you downloaded it from a website, it likely was corrupted during download, and I would suggest trying to download it again. If you downloaded it from a peer to peer network, the file may be a fake.
You maybe able to skip the check sum at your own risk:
Checksums are there to protect you.
To enable skipping of the checksum verification to speed up mounting. So use the following (in Terminal):
*defaults write com.apple.frameworks.diskimages skip-verify true*
This will turn off disk image verification system-wide, regardless of what client has requested the mount (e.g. Finder or Safari or Disk Utility or DiskImageMounter.app).

- Sep 27, 2017 Question: Q: Where can I download OSX Sierra DMG/ISO? Mac wont start! I upgraded my Macbook Pro OS to Sierra on Thursday Friday morning and its been a disaster. Crashing, not starting. So far with continuous trying over the weekend I cannot start in safe mode, restore mode. I have done boot with D and hardware check was fine.
- Mac OS X - How to disable the disk image verification You can skip disk image verification (checksum) to speed up the mounting of disk on Mac OS X (though it is not recommended). To disable this feature: Open a terminal and type the following command:% defaults write com.apple.frameworks.diskimages skip-verify YES.

Sierra(10.12.1)的确在设置『打开未知来源』时有变化。 我特地复现了题主描述的情况，请往下看： 1. 设为『允许 App Store 和认证的开发者』，打开未知来源程序，系统提示无法打开 2. Create bootable usb mavericks dmg on windows.

% defaults write com.apple.frameworks.diskimages burn-apple-supported-devices-only falsewould do?
You can use this applescript from NoName Scriptware. It also handles licensed disk images and boy is it fast.

I just Googled on the string: 'defaults write com.apple.frameworks.diskimages burn-apple-supported-devices-only false'
Looks like this question has still not been answered!
Surely someone will try someday and post the results here ..

If you install important things from Disk Images--especially if you install system updates manually instead of with Software Update--I highly recommend *not* doing this.
I got burned pretty badly by skipping checksums when I installed the 10.2.8 update from what turned out to be a slightly corrupted disk image. The install completed, but it rendered my entire system non-bootable. Only the fact that I had a second bootable partition kept it from being a total nightmare.
Why would anyone ever want to do this? Checksums are there to protect you. It's a safety mechanism to, in this case, verify the integrity of a disc image before you go making any assumptions & maybe do something destructive. How long does the checksum take -- a few seconds at most? Come on, this isn't a hint, this is an invitation to pain. Don't do this hint -- sooner or later, you'll regret it.

DO NOT LEAVE IT IS NOT REAL
Well, I keep one or two disk images of game CDs on my laptop so I don't need to carry the CDs around with me. When I want to play, I don't want to sit and wait while it checksums.
Just because a bad thing could happen doesn't mean people shouldn't have the choice or option of controlling their own computer..
I absolutely NEED this option for my children's computers. See, they play lots of kids games, and EVERY ONE of those games requires the disk in to play. Since that is not feasable for a toddler to manage - I have created disk images of all the disks, and mount them automatically at login. If I can't turn off the verify - it starts failing around disk 6, and can run for an hour before finishing sometimes, with random failures. Once I turn off the verify - they mount perfectly and work fine..
If the checksum only took a few seconds, I doubt anyone would ever wish to turn it off. However, for large images like CD images, this can take minutes to perform. The only way (previous to learning about this hint) to stop it was to click the 'Skip' button. It's precisely the length of time that causes people to want to turn it off.

oh quit your whining. suppose you regularly mount the same image over and over, it's a big waste of time! a couple of seconds? try a matter of minutes! it adds up, you could be using the data on the mounted disk, instead you're watching it verify something you know is working.
why don't you let people make up their own minds? who died and made you king that you feel you have to rain on everyone else's parade crying on a soapbox?! it's one thing to post a polite warning and another to condemn everyone who might not be as patient and lax as you.
hi,
when i write:
% defaults write com.apple.frameworks.diskimages skip-verify true
i have in the terminal the massage:
'no such job'
and the preference is not changed!
I have the system in portuguese, but i think is no because it!
any ideas to change that?
Tx
You are not supposed to type the percent sign (%), only the text starting with the word defaults.
skip the % and u should be alright.
am i correct?

Thanks Daniel Steffen! That tip is awesome. I have a couple of small kids that are quite independent with their Macs and I wanted to upgrade one of their systems to OS X. The educational software developers seem to think it is a great idea to have children manipulating discs, despite all the complaints they get from parents and teachers. Anyway I have a bunch of CDROMs mirrored to the hard drive and they all mount on startup. This little tip has to save twenty minutes or more! (P.S., works for Tiger.)
Hi, this worked perfectly. thank you. I have a quick question about it, how do I get it OFF? When I don't feel 100% confident about the source, I'd like to keep the checksum validation running. How can I put this feature back on or turn the command I entered off? Thanks in advance.
