<h2 class=top>MacOS Tags</h2>
<p>
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.</p>
<p>The tables below list some of the tags that may be extracted, but ExifTool
will extract all available information even for tags not listed.</p>
<p>Tags in these tables are referred to as "pseudo" tags because their
information is not stored in the file itself. As such, <b>Writable</b> tags in
these tables may be changed without having to rewrite the file.
</p>
<h2><a name='MDItem'>MacOS MDItem Tags</a></h2>
<p>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 <a href="../ExifTool.html#MDItemTags">MDItemTags API option</a> to 1 or the <a href="../ExifTool.html#RequestAll">RequestAll API option</a> to 2 or
higher.</p>
