How do you set an Burst ID using exiftools on MacOS?
MakerNotes

To add BurstUUID for non-iPhone taken photos, you need to copy in MakerNotes from an iPhone created image. See Re: Help with MakerApple metadata for a related discussion and example:

exiftool -v -overwrite_original -m -P "-burstuuid=$UUID" -tagsfromfile IMG_0178.jpg G0232134.JPG


Phil Harvey, the creator of ExifTool, says this about MakerNotes in relation to BurstUUID:


  No.  Makernote tags may not be created individually. They may only be changed if they already exist.  The only way to create them is to copy the entire makernotes as a block.  I suggest maybe creating a user-defined XMP tag instead, and writing this to your GoPro images.
