Welcome to Autodesk Forums!

Hi @Anonymous,

Can you provide more details about your problem?
- macOS version,
- AutoCAD version,
- which server are you using?
- what protocol you are using to connect to the server?

>>>>>I cannot open an xref by right click
Why?
- you don't see "Open Xref" item in right-click context menu,
- you see it, but when you select it nothing happens,
- you see it, but when you select it AutoCAD respond with some alert at the command prompt
Are you able to open Xref in another way - with a button on Xref Visor?
Are you able to open external referenced drawing with menu File -> Open?
