Dell Unity: Files created with "hidden" attribute after updating Mac to Version 13 (macOS Ventura) (User Correctable)

Since updating their Mac clients to macOS Ventura (13.x), certain newly-created files are being created with the "hidden" attribute set.

It currently appears to mostly impact .doc and .pdf files.

The exact cause is unknown at this time, but it appears to be an incompatibility between Unity and macOS Ventura.

Fix:
While this is an Apple issue, Dell has created a fix and has included it in Unity OE version 5.4 and newer.

Workaround:
If you cannot upgrade to Unity OE version 5.4, as a workaround, you can disable SMB directory leasing, which appears to minimize this issue.  

To do this, issue the following command in a Unity command line:

svc_nas ALL -param -f cifs -m smb2.capabilities -v 95

To revert this change, issue the following command:

svc_nas ALL -param -f cifs -m smb2.capabilities -v 127

There are some reports that disabling directory leasing is not solving the issue for certain customers.  While we have not yet validated this, a second alternative workaround would be to force the max SMB dialect to 2.1.  To do this, add the following to the /etc/nsmb.conf file on the problematic Mac client:

[default]
protocol_vers_map=2

Alternatively, you could issue the following command on Unity which would force all SMB connections on that NAS server to negotiate no higher than SMB 2.1:

svc_nas [NAS_SERVER] -param -f cifs -modify smb2.maxDialect -v SMB2.1

Again, that setting is per NAS server, and takes effect immediately upon reconnecting to the share.
 
To do that, issue the following command:

svc_nas [NAS_SERVER] -param -f cifs -modify smb2.maxDialect -v ""
