    Hi everyone so I used my mounatin lion backup from newer macbook air and used migration assistant to transfer everything onto my "refurbished" black macbook 2007 that runs Lion.. Everything works fine but the gives an error saying this version of os x not compatible. How do i delete and reinstall the .Mail app?
    oh and i dont have any install disks just fyi.

    thank you!

    It sounds like migration assistant pulled off Mountain Lion version of applications bundled with OS X to the Lion system. The only real way to recover is to install Lion again on the system to make sure all the applications are the right version.
