Keyboard or mouse light up during the night
What is it
When the Mac wakes to perform maintenance, it also wakes up accessories such as keyboards and mice (sometimes even displays). With M1 Macs, they typically wake 3 times an hour during the night, which can cause sleep interruptions if they're in the same room as a light sleeper.
Causes
- Apple's "PowerNap" functionality which periodically wakes Macs to perform maintenance.
- Various Networking reasons, periodically wake the Mac for maintenance and network activity.
Solutions
- Deselect "Wake for Maintenance" in "Sleep Settings" window of Sleep Aid.
If this Mac is a M1 Mac, please ensure that "Disable Wi-Fi during sleep" is selected, otherwise this can cause the Mac to have Excessive Insomnia, which will cause it to wake up every 5 seconds.
- Deselect "Wake for Network access" in the "Sleep Settings" window of Sleep Aid.
- Deselect "Wake for Watch unlocking" in the "Sleep Settings" window of Sleep Aid.
- Deselect "Keep network connections alive" in the "Sleep Settings" window of Sleep Aid.
- Select "Disable Wi-Fi during sleep" from the "Sleep Settings" window of Sleep Aid.
