Terminal Tip: Stop disk image verification

defaults write com.apple.frameworks.diskimages skip-verify TRUEIf 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.

This can be set from the preferences in Disk Utility also. Actually better from there because you can set two different options for when to check.

Instead of using the defaults command in a Terminal session, you can just launch Disk Utility and change the setting in its preferences.

"…sometimes [this process] is completely unnecessary. To stop disk image verification forever…"
Wait, what? Wouldn't the skip button be better for those times that the process is unnecessary? Babies and bathwater spring to mind...

Exactly. I would rather leave this enabled because unless the image is really large, it doesn't take a long time to complete. And, quite frankly, those extra few seconds make me feel better about the contents that I'm copying out of the newly mounted volume.

What about the "The disk image you are opening may be damaged and could damage your system. Are you sure you want to open this disk image?" prompt - I make DMG images in Disk Utility for my kids' games so I don't have to insert each disc for them and have them load on startup, but I get 10 prompts at every bootup. What am I doing wrong?

this happens to me too. same scenario with the kids' programs. i dont know what causes it... i think it might have happened after a security update, or maybe after upgrading from 10.3 to 10.4? don't remember.

The problem is you can no longer skip verification after creating an image as of 10.5, this fixes that.

Actually, this may not do what I'm talking about, I'd really like to be able to do that.

Now if only there was a way to cancel out of the "verifying..." time it takes after burning any kind of CD or DVD...

Nice! I'm tired of click the skip button.

Just repair the disk image in Disk Utility. You may first have to convert it to read/write if you imaged it as read-only.
