-Sidecar files are named "photoname.ext.sidecar_ext".  For example, if the photo is named `IMG_1234.JPG` and the sidecar format is XMP, the sidecar would be named `IMG_1234.JPG.XMP`.  Some applications expect the sidecar in this case to be named `IMG_1234.XMP`.  You can use the `-sidecar-drop-ext` option to force osxphotos to name the sidecar files in this manner:
