I had OS 10.6.8 installed on a remote drive that I used frequently so that I could use programs not supported by later versions of Mac OS. That drive crashed and I couldn't repair it. Fortunately I have it backed up using Time Machine on another drive. I bought a new drive and formatted it using disk utility. I am trying to restore the OS 10.6.8 from the backup drive to the new drive but I can't figure out how to do it. Any help would be appreciated.
