I use iCloud file sync behind the scenes to keep instances of my Mac application in sync so I have the entitlement set for that. Unfortunately, this means that iCloud also appears as a possible save location when I invoke NSSavePanel.
Because my app does not generate files that are intended to be reused or reimported back into my app, I have no iCloud open panel. However my app does allow the user to export simple HTML or CSV reports. I don't expect a reasonable user to choose iCloud as their save destination when exporting reports in my app, but Apple has now flagged this as a reason to reject the app since they conceivably could do that and then those files are effectively stranded in the cloud.
How can I suppress iCloud from the potential options when the user goes to save a file?
