There is a very good reason why WDC is stopping development of the desktop (macOS) support of personal storage such as the My Cloud Home on the macOS and it is iCloud. Apple is building a pretty good moat around their business and their customers are captive to their ecosystem and there is zero reason for Apple to support third party storage. Apple users could blame the third party device makers all they want but it doesn’t detract from the conclusion that this has been an Apple’s business decision.

Just for completeness, though, I did look at the documentation, and with ExifTool, do this:

exiftool -r '-DateTimeOriginal>FileModifyDate' directoryname

(Remove the -r if you don’t want recursion, and if you do that, you can also give a list of files or a wildcard instead of directoryname.) And be careful with those quotes — if you’re running this on Windows, you want " instead of '.
