LibreElec new install Samba not working

I have a raspberry pi 3 with LibreElec 8.0.1, I cannot get an samba share added to Kodi.
The share is an external drive on a Mac mini, I receive a broken pipe error.
I am mainly trying to add it as a new network location using the IP address of the Mac mini.
I see the Mac mini using zero config but it is not accessible.
Sharing (Smb) is setup on the mac and accessible from other devices. Guest account has privileges, firewall is off,
I have read of some having issues but looked to be related to android.
Can someone point me in the right direction.
