I've seen several posts in this forum that imply that Bittorrent Sync does not function if either of two peers is "sleeping." This topic is not addressed in the FAQ or (rather thin) "User Guider," "Desktop Manual," etc. So to be clear: Can anyone state authoritatively if both of two personal computers need to be "awake" in order to Sync? (If OS matters, I'm asking about OS X 10.9.1.) If so, this should be stated somewhere in the docs, as it is common to want to sync a home computer to a work computer. Typically, one of the two machines will be asleep. It's not rocket science to prevent my home Macbook from sleeping but it never occurred to me this might be preventing sync. This would also be surprising. My BitTorrent client (Transmission) functions fine during sleep, for both uploading and downloading, as do two other file transfer systems, CrashPlan and Dropbox. Thanks for any guidance.
