    Restart the computer and empty the trash.

  • 15 "MacBook Pro early 2011 screen and use failure, horizontal lines, edges off the coast of the center of the screen

    Hi there-

    recently worked when all of a sudden my screen turned to a variety of 'snow '. After about 2 seconds, he stopped, but the screen was seriously messed up. Horizontal lines apart a few millimeters, but the lines look as if they were moving a little. In addition, the edge of the screen is now near the Center, rather than on the edge of the physical screen. So, there is a black bar halfway in the screen which cut into 2.

    It froze the computer as well, if I pressed the power to restart. It loaded very well through the screen of apple, but as soon as he hit the login screen, he returned to no usable lines. Cannot get back in.

    Anyone that prior experience, or know what I can do to get out of trouble? Looks different from most other 'horizontal' issues I found in searching.

    Photo attached.

    Thanks and best,

    Curt

    You cannot use COLLECT LOOSE on scalar variables. The variables must be defined as a TYPE of COLLECTION to make in bulk to collect.

  • How can I get the videos and stills to appear in the order early in the timeline, and not all images so all the videos. I chose the oldest Date

    Hi I have a mix of photos and video clips loaded into my Mac Adobe organizer of the external drive, where they show (on PC) in the correct order as, still images and videos mixed. After loading in the Organizer, and chronology in first 12 items, I select more "old first". But in the timeline, stills appear first in the correct order, then after that video clips, in the correct order in themselves. Is it possible to actually load everything in the right order, IE pictures and videos mixed. Thanks Chris

    Chris

    Thanks for the follow-up.

    Be strictly one of the Windows elements, I can not give you a 100% guarantee for the use of the organizing elements Mac Albums to get your first items editor Timeline ordering media, but what I've read, the chances are good for working on the item Organizer organizing Mac as well as windows.

    We will review your progress as your schedule allows.

    I think the best would be a new installation of El Capitan on the new HD and reinstall the applications on the new HD, and then migrate the data and setting for the previous version of OSX. In this way the least unused stuff enters the new OSX version
