Use `mdfind` for a date range on OS X
To simplify and broaden the search you may use operands like >, &lt;, >=, &lt;= or line up several attribute values with &amp;&amp;.

To solve the above mentioned example you can use two different creation times and an item kind:

mdfind 'kMDItemFSCreationDate &lt; $time.iso(2008-03-15T23:59:59) &amp;&amp; kMDItemFSCreationDate &gt; $time.iso(2008-03-10T00:00:00) &amp;&amp; kMDItemKind = *image'
