Time Machine didn't copy all files to new Mac
I just bought a new Mac and when I set it up, I copied all data from my external hd (time machine). But then realised, that lots of files were missing on my new machine. Mainly InDesign files. I've already contacted apple (they blamed InDesign). And I just contacted Adobe (they said its time machine). Now what? I don't know how much data is missing and why?! Lucky I can still access them on an older backup, but its still scary and should not be?! Anyone had the same problem?
