The problem
Large file transfers over AirDrop, network shares, or FTP can fail when your Mac sleeps. The transfer pauses or the connection drops entirely.
Why it happens
File transfer apps rarely request sleep prevention. macOS treats them like any other app, and when the idle timer expires, the system sleeps and the network connection drops.
The fix: Shake It On
Shake It On keeps your Mac awake by moving the mouse slightly at regular intervals. macOS sees real user activity and resets the idle timer. Set it up with the right conditions and it only runs when you're actually file transfers.
Recommended conditions for file transfers:
- Only Shake If Wi-Fi is connected (with optional SSID match for trusted networks)
- Only Shake If a USB device is connected (when transferring to/from a specific drive)
- Paused When on battery
Shake It On keeps your Mac awake during file transfers with smart conditions. $9.99 one-time.
Keep your Mac awake the easy way.
Shake It On lives in your menu bar and uses organic mouse movement to prevent sleep. Set it once and forget it.
