Thank you . I have been trying for hours now and I can’t access the network folder still. I think this is a problem on my Mac. Is there any other possibility to send my MKV files from my Mac to the Raspberry, that is easy to use? Like AirPlay only compatible with MKV? That would be fine.
I made the things you told me, but it is not working. I solved this problem by buying AirParrot 2, which is allowing me to stream mov files via AirPlay. But isn’t it a little bit strange, that a software, which is made to be a media center isn’t supporting File Sharing in a LAN Network? I am still interested in, how it could work, but now I have AirParrot as a interim solution until someone can make a Step-by-Step solution, which (I believe) isn’t only interesting for me, but for other OS X users too.
