When connecting an external drive/SD card/USB thumb drive, the dialog box asking to trust connection pops up for a very quick flash then disappears preventing the drives from being mounted.
Is there any way to fix this, or to disable the security step and have all drives mount without approval?
Thanks

I agree P. Phillips' responses were less than helpful, however, the link does give a hint to a solution that worked for me.
I too was having the issue where it would flash for a second and then disappear. While I'm not sure how to fix that issue, I was able to workaround the issue and access the drive by going to System Settings -> Privacy and changing the "Allow Accessories to Connect" from "Ask For New Accessories" (which I think is the default) to "Automatically When Unlocked". This did allow my SD card to mount so I could access it. You could always revert back if you're concerned with security.
Hope this helps Mike and Lewis!
But is there a reason why the screen is automatically disappearing/submitting? What if I actually want to choose which items to approve or disapprove?
Exactly, when is this bug going to be fixed?
I have the same issue. Reported it as a bug via apple.com/feedback.
This worked for me, to the point where the drive was mounted on the "other" account and not on "main".
Just wanted to say thanks for this suggestion!
The problem for me was having more than one user logged in. Lately I started using Fast User Switching to keep my private life separate from my work life using two user accounts and just fast switching between them (so I don't have to lose my place in apps when I switch users).
This seems to have a negative effect on system level popups like this accessory attachment permission question. Apple should fix this, since fast user switching is a first class and great feature. But it does break these popups, preventing new drives from being connected.
The solution for me was to log my other account out and switch back to my main one, then attach the drive and answer the popup.
