In order to  partition my "vintage" MacBook Pro to run Bootcamp, I've had to go back to the previous OS (Mountain Lion), and before erasing my hard drive I did a full backup to Time Machine.   Once I connected the external HD to the "mountain lion" laptop and I went to the Time machine, and was prompted to start it up.  After a backup process I looked at my time machine disks and see the backup, but the times prior to this last backup are greyed out.  If I go to each prior backup session I can see the files and even copy them to my laptop, but they won't open.  I receive a prompt to install them from the original disks.

I don't seem to be able to recover files from the Lion Time Machine backup to the Mountain Lion.  

Is there a "trick" or workaround. 


MacBook Pro, Mac OS X (10.6.8), vintage model

    I'm a little confused.  You say the previous OS was Mountain Lion, but Mountain Lion is the most recent there is.


    Then you say you're unable to recover files from the Lion backup.


    Please clarify exactly what you have, and what you're trying to do. 


    If you want to restore your entire OSX partition, including OSX, apps, user accounts, settings, and data, you can do that from any backup, but not via the Time Machine browser (the "Star Wars" display).  Instead, you do a full system restore, per Time Machine - Frequently Asked Question #14.

    Reverting from Lion to Snow Leopard is a problem.  Some apps, especially Apple apps such as Mail, aren't going to work with the Lion file/folder setup.


    When you erase a disk, it's treated as a different one for some purposes, so most likely, that's why the earlier backups are grayed-out.  You'll need the procedure in the green box of #E3 in Time Machine - Troubleshooting to see and restore from them.


    You might also have a problem with permissions, if the user account you're now using isn't recognized as the one that was backed-up.  You'll see the small red "no entry" icons.  If so, try a different user account (create one if necessary).
