Ok, So I've been forced to get a Mac due to the number of Apple machines I'm working on these days, and I've come across a little issue... How the hell do you get OS X El Captian 10.11.4 to connect to a Ubuntu 16.04 Samba share! I go CMD+k, type cifs://192.168.0.13 in the server address field, hit connect, the Mac finds the server, I enter my username and password and immediately get a 'There was a problem connecting to the server 192.168.0.13' error. I know this is defiantly my username and password, but the Mac will not authenticate the machine! I know the Samba share is working fine as it is shared with every other device in the house, namely 2 x Windows PC's, 2 x Nexus 9's, 2 x Nexus 5's and a WDTV but for the life of me I simply cannot get my main Ubuntu Mate 16.04 machine to authenticate on the Mac! Any ideas?
