SD reader el capitan
I have a late 2009 iMac and just upgraded to El Capitan. The SC card reader no longer works. The rider is not seen in Disk Utility and when I insert an SD card from my Nikon Camer, it does not mount nor does it who's up in disk Utility. I would like to understand if this is an upgrade issue and if so, when a fix will be distributed.
