CF Card Change Metadata Attributes

I purchased a used canon camera and it came with some CF cards. the previous owner name appears in the raw files under the “author” metadata field. The seller told me he added his name using window XP, which i do no have. I have access to windows 10 and apple ox s catalina.

My question is how i change the default attribute for the author under my name by using a newer operating system.

You can modify it in Canon EOS Utility (or similar for MAC, which is placed on the original Canon CD ROM, bundled with the body).
