    I was wondering if anybody knows if its possible to restore a mac from Yosemite back to Mavericks using Time Machine via one of these methods:

    -Clean install of the OS and use Migration Assistant.
    -Restore from Recovery HD using "Restore from Time Machine Backup".

    Thanks for your help!

    I just did that last night on my MacBook Air:
    • It took a few hours and the display went into sleep mode. Pressing a button turned the screen back on but it did not display anything (it stayed black). But the process was still going on and this morning it was finished.
    • After restoring my 10.9 backup I had to reenter my Dropbox and my Apple ID passwords. Also had to "import" all my old mails but it did not store them twice or something like that.
    • The App Store downloaded a "Mavericks Developer Preview Recovery Update". With Yosemite the Recovery HD had been updated and this seems to revert that change.

    The black screen during the restore process may have been be a bug in the new Yosemite Recovery HD but the process still worked. :D

    Ok- can you restore a backup made in Yosemite? Or does the backup have to be from in Mavericks?

    Also, I'm curious - why did you have to downgrade?

    Thanks again!
