They should be in the Public folder, but only accessible (= only readable) by certain people. Thus I would like to create a new group that has accession rights to these files. Strangely, the group command doesn&amp;rsquo;t exist on MacOS X (chgrp does exist though). I downloaded the 
 &lt;a href="http://www.avalon.net/~tmcintos/software/UserManager/" target="_blank" rel="noopener noreferrer nofollow"&gt;User Manager&amp;nbsp;






 
 
 
 &lt;svg class="svg-inline--fa fas fa-up-right-from-square fa-2xs" fill="currentColor" aria-hidden="true" role="img" viewBox="0 0 512 512" overflow="visible"&gt;&lt;use href="#fas-up-right-from-square"&gt;&lt;/use&gt;&lt;/svg&gt;&lt;/a&gt;
 application. But the version for OS 10.2 was not really easy to use. Thus I used the NetInfo Manager. I duplicated an existing group, changed its name to &amp;ldquo;gck&amp;rdquo; and id number and added two users (if you have more than one entry, you have to add them in brackets and comma-seperated). Then I created a directory in my Public folder and changed its group to &amp;ldquo;gck&amp;rdquo;. Permissions for this directory are drwxr-x&amp;mdash;. The files inside this directory also belong all to the &amp;ldquo;gck&amp;rdquo; group and have -rwxr&amp;mdash;&amp;ndash; permissions.&lt;/p&gt;</description></item></channel></rss>
