I have a custom app running on a Mac Studio with Ventura that grabs a snapshot image from a network camera. It then adds some extra information into the EXIF "MakerNote" field. However the metadata cannot be read back out of the image when running Ventrua, it can however be read out of the same image file on a Mac that is not running Ventura.
It would appear Apple has removed support for reading MakerNote in Ventura but still supports writing MakerNote in Ventura.
This code is about 7 years old and written in ObjC and has worked with no issue until Ventura came along.
Calls used
CGImageDestinationAddImageFromSource(); // used to write the image to disk with the extra metadata - Works on Ventura
CGImageSourceCopyPropertiesAtIndex(); // used to read the meta data from an image - does not return "MakeNote" data
Is there a new way to read EXIF "MakeNote" data from image files that was introduced with Ventura?
