MacOS Tags

On MacOS systems, there are a number of additional tags with names beginning with "MDItem" and "XAttr" that may be extracted. These tags are not extracted by default -- they must be specifically requested or enabled via an API option.

The tables below list some of the tags that may be extracted, but ExifTool will extract all available information even for tags not listed.

Tags in these tables are referred to as "pseudo" tags because their information is not stored in the file itself. As such, Writable tags in these tables may be changed without having to rewrite the file.

MacOS MDItem Tags

MDItem tags are extracted using the "mdls" utility. They are extracted if any "MDItem*" tag or the MacOS group is specifically requested, or by setting the MDItemTags API option to 1 or the RequestAll API option to 2 or higher.
