I have a fresh install of Sierra on a new HD in my old 2009 iMac 27" , I used migration but only for computer and network bits, I'm copying he rest manually. Trouble is when I try and drag a network share from my Mac Pro to finder nothing happens, I get no red line, not option to drop it. I can drop a document but not the share. So I tried creating an alias of the share then dragging that, still no joy..I then tried ctrl/cmd T and it created a favourite but the share has no name just a ?.. I've searched for the past 2 hours for a solution and found many with similar problem but no solution, has anyone any ideas please? I did trash the shared preference & reboot but same problem.. Appreciate any help this is driving me crazy..
