Apple Photos has changed the exif date of 30+ photos to 9999, how to change them?

[blackxacto]

19,1 iMac w Sonoma 14: Once upon a time, I had an issue w Apple Photos. Somehow I accidentally changed the exif dates to 9999 on maybe 30+ photos. This has completely screwed up their storage in Photos. They either appear in the front of the photos stored or they appear at the end. Don't ask me why. So I want to change these files exif dates and maybe more. No matter what I do to them they retain the exif dates. Does anyone know of an application that actually works to change exif data. I have purchased some in past, but they don't work. I again am tired of seeing these weird photos showing up anywhere.

If you're comfortable with the command line (or don't mind getting comfortable with the command line), I'm the author of the free open source tool osxphotos tool which can do this. See install instructions here. osxphotos contains several utilities, one of which is `osxphotos timewarp`, a command to bulk change date/time/timezone/date added, etc. See help for timewarp here.

How did you change the date? Photos.app *never* changes the EXIF in the original data -- it only changes the data stored in the Photos library database. So if the data in the original file is correct and you changed the date in Photos, this would work. Select the affected photos in. Photos then run this:

osxphotos timewarp --pull-exif

The timewarp command has many other options described in the docs.

One caveat: for the `--pull-exif` to work, the original file must be on disk which means you must have set the "Download Originals to this Mac" option in `Photos > Settings`.
