How copy "Modified date" to "Created date"?
For some reason, all my photos have had their "Created date" changed to a date in 2015? I do not have a back-up I can restore (have over 30,000 pictures), but both the "Modified date" and the "Last opened" date remain as the original "Created date".
Is there ANY way to copy either the "Modified date" or the "Last opened" to replace the "Created date"?
ANY suggestions very much appreciated.
Thank you and happy new year,
Kenneth
I am using a MacBook Air with latest Photos and OS installed.
