Set file creation date before 12/31/1969
I have files of photos and other documents on my Mac which I want to "date" earlier that 12/31/1969 so that they sort in the correct date order. However, while I can reset the date with the Terminal line command "touch -t YYYYMMDDHHMM filename", this date reverts to 12/31/1969 when I reboot.
How do I get these dates to be permanent?
iMac (Retina 5K, 27-inch, Late 2014), OS X Yosemite (10.10.5)
