I don't believe there is anything special about the volumes that I'm mounting. I'm in a similar position as @vnijs, where everything works fine for version 1.1., but not version 1.2.. Additionally, on windows this doesn't cause a problem. That is, I'm able to run version 1.2.* just fine on a window machine, mounting to the same network drives.
On my Mac, I'm connecting to the /Volumes/aai_general/ server using an smb mount (i.e., Finder > Go > Network > smb://path_to_network_drive).
The other network drive (called mount-acf), is my connection to a high performance computing cluster. For that, I connect using sshfs. In the terminal:
$ sshfs username@network.address.org: ~/mount-acf -ovolname=mount-acf
