OSX 10.12.4 Beta - Verifying dialog on opening any movie/zip files?

[victorhooi]

Hi,

I recently upgraded to the OSX 10.12.4 public beta.

However, I've noticed whenever I try to open a video file or zip file - it gives me a verifying dialog, which seems to hang for a while:

Is anybody else seeing this issue?

Thanks,
Victor

zip files seem ok here (i don't have any video files to test)...

Is that MP4 an actual video or a DMG file renamed to MP4? As far as I'm concerned only my DMG, XIP, and PKG files have ever given the verification dialog.
Perhaps it's a signed file?

It's an MP4 file. Output from file:

foobar.mp4: ISO Media, MP4 Base Media v1 [IS0 14496-12:2003]

I can do some tests with some other files later - just wondering if anybody else has hit this before.

If it makes a difference, I'm using mpv as my video player.

I do recall seeing a similar issue (Verifying dialog on video files) in older OSX betas (i.e. before Safari) - so not sure if this is just a temporary bug.

Getting the exact same thing when opening any video files in VLC 10.12.4 beta.

The bigger the file, the longer it takes.

Can anyone expand more on this?

Yup. Doesn't matter if opening with Quicktime or 5K Player or VLC. Every video file experiencing the same issue.

10.12.4 is still on public beta 1...

i know but im on beta 2 dev, and its even worse than beta 1 now takes longer to open

Hmm? Is there anything to do with validating media player apps? Just a guess.

I did see archive files being verified before but the file size was small. (Around 10 MB) This happens in another version of Mac OS X.

ugh... maybe we're all supposed to only watch QT videos, or itunes video...

try use :
xattr -d com.apple.quarantine "foobar.mp4"

add -r if you want it become recursive

It works for me, thank you. How to execute this for all files in a folder?

This is my first message here. Hi to everyone!

Try this:
open up terminal.app and run this:
defaults write com.apple.LaunchServices LSQuarantine -bool NO

Please Note: Restart is required to make it work.

I got 'verifying' happening with time I opened a .mp4 file (VLC Player default - but it would always then start the file), but with recent MacOS update (10.13.3), I might not even get the 'verifying' check, and VLC Player (also updated) would just not start file and then freeze up.

Some talk elsewhere of changing file from .mp4 to .m4v resolves the verifying issue - but I tried that and I still got the verifying issue. On the plus side, once done, VLC played the file, where it wouldn't before. On the other hand, am I really ready to manually swap out the file type for this?

Also some talk of Avira AV being an issue - turning off 'real-time protection' seemingly disabling the verifying and VLC immediately opening the file. So that may be something you want to try?

Something has gone seriously squiffy somewhere.

I solved it by running on Terminal de following:


xattr -d -r com.apple.quarantine ~/Downloads

I had a .rar file I could not open without the Verifying message. I drop this .rar file in the Downloads folder, I tried to open it, and it worked!. Hope this helps.
