Hi Guys, I've tried to add File Provider Extension target for macOS but not successful. This option is still not visible on Xcode 12.3 (12C33) and macOS 11.2 Beta (20D5029f). I really hope we can start using this API to build on-demand feature for our product, it'll be really usful. Does anyone know when this API will be available for public access? Thanks. Chih

Hi @clenart , Thanks for the replay! I know that addDomain needs a valid displayName, but my problem is a little different. While I create NSFileProviderManager object (using above snippet code), sometimes it'll change displayname of a already added domain. I found more detail log today. It seems that fileproviderd detect displayname changed and did change the domain info and physical directory path. 2022-11-30 17:29:14.657796+0800 0x6c5f Default 0x0 1332 0 fileproviderd: (FileProviderDaemon) [com.apple.FileProvider:default] [NOTICE] need a new domain for <private> because display name changed Can you help to reach developer team and check whether this is an bug?

This forum will eat me comment... so I use replay here. I'm not sure which code I need to provide here, there are a lot of them, but I did use disconnect before program exit and reconnect after program start! This problem did happen frequently when program exit and/or start. Maybe this can provide some insight. thanks :)
