Does SAP GUI for Mac 7.50 rev 8 support network location for SAPUILandscape file?

We have the SAPUILandscape file available for our windows clients on a network share which teh GUI accesses using a path //abc.com/aabbbcc/SAPUILandscape.xml

However, for the mac users, we have been unable to configure it using smb://abc.com/aabbbcc/SAPUILandscape.xml

Macs in question can access network shares using smb without the need to input passwords, so, SSO is working for sure, however, network access of that file does not work on Macs.

Any help in this regard will be appreciated.
