I'm currently running OMV 4.x on my Odroid HC2. The image I downloaded from sourceforge. Everything works fine and I can use Samba to transfer file. My Odroid HC2 is connected on a Netgear 8 port gigabit switch and I can transfer large files (e.g 2GB) @ about 45~50 MB/s from my Macbook Pro 2011 (which also has Gigabit Ethernet port)
I have seen youtube video and Odroid/Hardkernel Wiki they transfer @ about 80~90 MB/s. I thought because I'm using a Mac, I should try enabling (AFP) apple filing for better transfer speed - which I did in the OMV interface and setup user and access right just like I did on Samba. On my Mac's finder I can see a network shows up but when I try to connect it doesn't accept my username/password.
I'm not sure what I did wrong? Do I need to set anything special on my Mac machine? note that I have no trouble sending files over SMB. Any hints is very much appreciated.
