# What happens to Collab Sync while the other Mac is asleep or offline?

Nothing piles up. Collab Sync waits, and the moment the other Mac is reachable again — on the same Wi-Fi or across the internet — the two folders do one catch-up pass and they're back in step.

A file you changed several times while disconnected is sent once, with its final contents. Meanwhile the folder shows **Waiting for ‹the other Mac›**.
