Bridge & your devices · Collab Sync
How do I accept a Collab Sync request from another Mac?
Short answer: Open the “‹their Mac› wants to sync a folder with you” request, choose where on your Mac to keep the folder, and tap Grant — or Decline. Nothing is created on your Mac until you grant it.
When another Mac asks, Collab Sync shows “‹their Mac› wants to sync a folder with you”, with the folder's name, size and file count. Choose where on your Mac to keep it, then tap Grant — or Decline.
Nothing is created on your Mac until you grant it, and you always pick the location yourself.
