I have been using Resilio Sync v2. 7 on My Cloud OS 3 with clients on Windows, Mac and a Drobo NAS.
It seems that Resilio Sync is no longer “built in” and the downloaded binary MyCloudPR4100_ResilioSync_2.7.2.1375.bin does not install (PR4100 claims it is incomplete)
When will WD add in this support again?
