    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

    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.

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

    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.

    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.
