## NAME
    [Image::ExifTool::MacOS](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool%3A%3AMacOS/markdown) - Read/write MacOS system tags

## SYNOPSIS
    This module is used by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown)

## DESCRIPTION
    This module contains definitions required by [Image::ExifTool](https://www.chedong.com/phpMan.php/perldoc/Image%3A%3AExifTool/markdown) to extract MDItem* and XAttr* tags
    on MacOS systems using the "mdls" and "xattr" utilities respectively. It also reads metadata
    directly from the MacOS "_." sidecar files that are used on some filesystems to store file
    attributes. Writable tags use "xattr", "setfile" or "osascript" for writing.
