So, I've finally bit the bullet and gone from good old realiable snow leopard to mavericks. After the update, my connection to my NAS (plextor unit, supports afp) no longer works. I've been trying out the various help guides online, but still no joy (finder has the "version of the server you are trying to connect to is not supported" dialogue). Following the official apple guide at http://support.apple.com/kb/HT200160?viewlocale=en_US, craps out at step 4. basically i just cant seem to connect at all. Using the NAS's web interface I've created a test ID to try to eliminate that, but thats still the same issue. Does anyone have a solution for connecting to AFP (please dont do the 'use a different protocol' reply).
