This is for Carbon Copy Cloner 4 users. The software no longer runs on anything pre-Mountain Lion. My problem is that I have a bootable backup of a Tiger(10.4) drive. I have it for archival reasons. Can I use CCC 4 to backup a OS X 10.4 bootable drive on to another. Will it work? Currently I am using the CCC3.5 version for this. I use my OS 10.9 laptop, connect the 10.4 drive "source" then clone it to another HDD for "destination" . I asked in their support forums but they said its supposed to work but they never tried it and I can't risk it.
