Is this a known problem, perhaps associated with the Mac OS change from the HFS+ to APFS file systems? Is there a fix?<div class=""><br class=""></div><div class=""> Thanks,</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Mark Klein</div><div class=""><br class=""><div class="">
