    Ciao everybody, I'm new in this forum.
    Yesterday I updated the new OSX, but something does not work, and I would like to return to my previous system. I had done the BU with TimeMachine, but Meverick does not recognize the old BU. How can I do? I strongly hope that it's still possible.
    Thanks for any help!

    Please explain this a little more. It may be possible to fix this something, rather than the drastic option of downgrading.

    Assuming your Time Machine backup was with Lion 10.7.2 or later and to a USB or Firewire external drive, you should be able to option key boot to the Time Machine drive and restore to the old OS. Of course an new data you acquired while in Mavericks will be gone.
