iCloud downloads change EXIF data, Airdrop doesn't
The correct metadata is available for all images stored on iCloud, hence the accurate organisation in the iCloud database.
When downloading from iCloud on Mac, the EXIF data is sometimes kept for the Content creation Date, and sometimes changed to the date of the download, even when requesting to download the unmodified originals.
The same image that repeatedly downloads with changed EXIF data will download correctly via Airdrop. The process is however slower.
Any good reason why this is happening? It has been the same situation for several years now and one would have hoped it was possible for Apple to correct, at least within the ecosystem.
The problem is within iCloud as it is browser agnostic at least on the Mac.
Below is the metadata for the same image downloaded and airdropped.
