    My iMac is going nuts since I upgraded to Yosemite. Spaces automatically lock up in between screens. I asked help from Apple Support. Did as I was told on how to reinstall using recovery method. Problem is, Yosemite won't install. And now I have deleted my whole drive. Any help? [​IMG][​IMG][​IMG]
    When using a USB DRIVE to install this comes out

    Brought it to Senco. I have a broken video card.... Which I don't understand. They are charging 30K for repair. I said forget it. I'm selling my aluminum to the junkyard

    that's unfortunate but I'm not surprised that the video card broke down.. they are charging P30k probably because it means a logicboard replacement.

    If you can still boot normally to the desktop, do so and launch the Yosemite installer app.

    If you've created a bootable Yosemite install disk, you can also use that to do a clean install.

    What I did on mine when this happened, when you have adequate time. Go try to find Mountain Lion installer, instead of Yosemite, after you have installed the Mountain Lion OS, try to upgrade to Yosemite from the Appstore. Let me know if this works for you.
