Every time I go to Finder and I select a shared folder in other macs on the same lan I notice that there is a long delay before the content of that folder is displayed.
The network monitor of Little Snitch shows me that uploads and downloads are performed to icloud.com. When these uploads and downloads stop, the content of the shared folder is finally shown in Finder.
How can I stop these downloads and uploads to icloud.com happening when I select with Finder a shared folder in other macs on my same LAN?
Please notice that all my macs are on mac os x 10.12.6 Sierra.
