    Hello folks,

    I have this weird Preview bug. I'll let this video explain it better.

    Here are some notes:

    - I have sent the same photos used on this troubled mac to another mac to test them out, and they worked perfectly on the other mac.

    - Sometimes it works, and sometimes it doesn't using the same file. I have no idea why.

    - On this same mac, I used to be able to edit photos without any problem before upgrading to Yosemite.

    Your insights will be much appreciated.

    Thank you.

    Create a new user account, reboot and login to the new user account. Does the issue still happen?

    I have the same thing happening here, since installing Yosemite.
    Preview version 7 from Mavericks still works fine.

    I thought it may have been because I'm running Yosemite on an unsupported MacPro (1,1 flashed to a 2,1), with an unsupported Nvidia card.

    I pulled a copy of Preview ver. 7 from my Mavericks Time Machine backup, and put it in my Utilities folder, then I set all .jpg files to open with version 7.

    Not the best solution but it works.

    Edit : Oh yeah, almost forgot.
    The same thing happens when I edit photos in Pixelmator too.
    The only way I can get Pixelmator to work is by editing in 16 bit per channel mode.
    Maybe that has something to do with it .

    Hopefully this helps.

    - Jay
