verifying progress bar on every file.

Hello, I was able to get rid of this annoyance. 🙂

Just launch this command in a Terminal opened in the folder that contains the involved files:

xattr -d com.apple.quarantine *

It will delete the quarantine flag from file's extended attributes and the verification won't appear. Replace the * with a filename/pattern if don't want it to affect every file.

Hope it helps.

Actually, Apple has to determine source of the problem, not user. Not only that, they even have to find the problem during testing phase. Anyway, thanks for checking out that on your system there is no problem.

Now there is another update - by doing a clean install (wiping the drive and reinstalling from internet recovery) I have managed to "fix" the verifying problem on 2 separate machines.

Turns out that Apple support were just telling lies to me, or maybe those were not lies but their creative thoughts. Quite disappointed, because had they told me that there should be no "verifying", could have had a working Mac way sooner.

i've had same problem but i solved. in my case the reason is "Avira". After truing off real time protection of Avira, it was just solved. all file is opened immediately.

turning the quarantine off completely seems to solve the problem

run this and reboot:

defaults write com.apple.LaunchServices LSQuarantine -bool NO

I found this:

Run the following command in terminal window:

defaults write com.apple.LaunchServices LSQuarantine -bool NO

then restart computer.

worked for me, good luck!

Looks like the issue is fixed. I have two machines, my primary Mac I've held off updating. My wife's computer had the issue and just installed 10.13.1 and appears to resolve the issue on the limited large video files I've tested. I'm planning to update to 10.13.1 on my primary machine and will update if I have further problems.

Whereas for me it was a simple delete of an application "Avira" and everything was back to normal...media files open without delay or any verifying process nothing whereas you had to do a complete re-install. I take it Apple Support didn't suggest to you to delete any anti-virus software or turn off FileVault?

After trying a few things out while on the phone to Apple Support, we went for an erase of the hard drive and complete reinstall of the OS, which solved the problem.

Update on this issue:

According to Apple Support, this "verifying" is an "expected behaviour of the system". They are using some "completely new file type" and everything that is not this "completely new file type", needs to be verified.

However, Apple recognises that waiting 5 minutes for this verifying is not exactly how OS should behave and they are "working on it".

Finally, as this "behaviour" is known already since Beta, I wouldn't hope for any quick success. Obviously, developers do not have large files to handle.

Unfortunately, after talking with Apple again, it looks like fix is not coming.

Apparently they now understand what is going on with their OS, and it's "intended". When asked who "intended" such a strange behaviour of the OS, they explained that it's "executives" and they are not challenging executive's decisions. Even they said they were "very sorry" for my lost workflow. Go figure.

After that, I was told that they have explained my "options" (to use as it is, or to roll back to El Capitan) and advised me to deal with it. Great advice, I would guess.

Had to recovery mode. Command option r on start up. Then deleted internal HD. Formatted to AFPS. started as new mac. Then had to drag and drop files from time machine backups to new user. It worked out pretty good. All I lost was previous settings. Hope this helps. Kind of a pain.

Hey!

I HAVE A SOLUTION (don't know if temporary or permanent).

I changed my samba share connection script from:

smb://<share name>

to

cifs://<share name>

and now it is working as before!!

Let me know your experience on this.

I have the same issue on 2 separate machines and I suspect that everybody has it.

It apparently is XprotectService scanning the file. On local SSD 5.5GB file is scanned in few seconds, so smaller file may not even display the progress bar. But on NAS, the same file takes up to 5 minutes to scan.

SO, it just requires fixing. Checking can be done in Apple offices too, not only users need to test software.

Thanks.
