Skip "Verifying [file name]" in High Sierra?

I am having this problem with ALL files, seriously slowing my iMac with 24GB of Ram - so it's not the system it's the bug. Any idea when Apple is going to fix this? I have clients that are basically freezing because of this Verify problem as well.

I found this:

Run the following command in terminal window:

defaults write com.apple.LaunchServices LSQuarantine -bool NO

then restart computer.

worked for me.

Happens to everybody except Apple testers because they don't have large enough files to notice the message.

@da250 but this is bad. It turns off this security feature system wide which is there to protect you against downloaded malware. It's better to wait Apple to fix this on the next updates.

Nope - changing this didn't work for me. Very annoying indeed.

Have the same problem. 4GB mp4 file on my timecapsule with vlc, stopped trying after 20 mins. My god so annoying.

This worked for me as well. Thank you.

here are the parameters to remove that attribute on an entire directory of files all at once:

find /path/to/my/directory -type f -exec xattr -d com.apple.quarantine {} \;

i hope this helps someone.

I guess with the newest update 10.13.1 this "verifying..." went away. I just tried opening .mp4, .mkv files and no more waiting.

The newest update 10.13.1 as of last night seems to have rectified this issue. Man that was annoying. I was just about to revert to Sierra.

Thank you so much. I just disable real time scanning before I want to use media files and all is well. Then re-enable again after. Hope they come up with an update solution soon.

It clearly is not another program causing the problem it is High Sierra bug - it MAY be conflicting with other programs, but it is not a single program that is causing this.
