I was ready to fully embrace BitTorrent Sync (2.2), but have come across permission errors. Folders that are server shares are not able to be synced, even if they are physically attached to the computer and not shared via network. It complains that it doesnt have write permissions, which is understandable, as read&write permissions are only set to group and using ACLs (Access Control Lists). BTSync could very easily be able to write to those folders, by authorizing itself to do so by entering the user/admin password in OS X. That is how all other software gets to write to places which need higher permissions like system folders. If BTSync does not have hightened permissions than its useless in an environment where permissions are set properly. That would be a real shame and I dont see any reason why it shouldn't. ANY other software has permissions to write to those folders, so why would BTSync not be able to have permissions? Thanks for considering, Armin.
