I wonder what
% defaults write com.apple.frameworks.diskimages burn-apple-supported-devices-only false
would do?

2019-9-28  Whenever I open a.dmg, my computer says that it is Verifying for a moment. I'm just curious as to what it is doing at this time. Is it running a checksum, checking if it is the same as the online. THIS TUTORIAL WILL GUIDE YOU HOW TO FIX APPLICATION THAT GETS STUCK ON “VERIFYING” IN MAC OS - IN THIS VIDEO: Batch code: xattr -d com.apple.quarantine Note that there should be a “space. This verification ensures that the application is not tampered with, so I would consider re-downloading and re-installing any app that fails to verify. If you have an installer package and you're sure it validates by checking the checksum or you have a backup and no data that would be sensitive if it's compromised - you can force the installer.

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 ..

hehehe. thank goodness for this hint!!!!!! i've been wondering how to skip it automatically since panther did away with disk copy and its preference screen!

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.

You could get seriosly hurt if you leave your house - so instead of giving you the option to leave, I'm going to come over and nail your doors shut.
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. /download-handbrake-mac.html. 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.

Mac Skip Verifying Dmg

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?

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?

I use this hint. Mounts simple DMG's fast. If there's a DMG with a license agreement, I have to use DiskCopy, though. Has anyone tried this defaults write.. hint in Jaguar to see if it work there, too?

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.

The data in a disk image can be corrupted if a problem occurs while it’s being copied or if someone modifies it. You can see whether a disk image’s data has been corrupted by verifying its checksum, which is a calculation of all of its data. When a disk image is created, a checksum is computed and stored with the image. When you open the disk image, a checksum can be computed again and checked against the stored checksum. If the two checksums match, the disk image’s data hasn’t been corrupted.

You can choose when to compute and verify checksums. Be aware that doing so can take a long time.

  1. In the Disk Utility app on your Mac, choose Images > Verify, then select the disk image that you want to verify.

  2. Click Verify, then click Done.
