I'm trying to find a tool which will allow me to change a file's creation date ansd from what I've read, using the "touch" terminal command you can change both creation and modification dates as long as it's changed to something earlier than the current modification date, but I haven't gotten this to work. In theory the following two steps should handle it (with 2012-09-14, 10.01 am as the creation/modification dates): $ touch FILENAME.PNG $ touch -t 201209141001 FILENAME.PNG ... but no matter what I do it only changes the modification date. From what I've read it used to be possible to change the creation date without any restriction, but with OSX 10.9 Mavericks the above restriction should apply. Have I misunderstood, and it's actually no longer possible to change the creation date with "touch"? I'm on OSX 10.9.5.
