    I recently purchased an iMac. When using Quick Look on videos, it works...for a while.
    Maybe for a few days. Then I get the message: "An error occurred with the preview of this document". It will work if I reboot the computer. This is happening over and over again. I've tried deleting/rebuilding the cache, but it doesn't help. Any idea(s)? Thank you.

    Never heard of that problem.

    I've never had a problem like that from Quick Look from all my years of using it.

    Are you running off an HDD?

    I've tried it on files running off both externals and local drives.

    I've tried running a permissions repair and have run that command as well, but it still happens.
