Excessive Insomnia
What is it
Excessive Insomnia occurs when the Mac wakes up an unusually high number of times an hour or even a minute, to do a little task and then go back to sleep. Intel Macs wake around once an hour, while M1 Macs will normally wake 3 times an hour.
We've only seen this problem with Apple's M1 Macs, but it may also occur with Apple's Intel based Macs.
Causes
- "Wake for Maintenance" is disabled on a M1 Mac.
- High volume of network activity is causing the Mac to wake up frequently.
- Apple AirTags appear to cause "Bluetooth Ache" with some M1 Macs.
Solutions
- Ensure "Wake for Maintenance" is selected in the "Sleep Settings" window of Sleep Aid.
- Deselect "Keep network connections alive" in the "Sleep Settings" window of Sleep Aid.
- Deselect "Wake for network access" in the "Sleep Settings" window of Sleep Aid.
- Select "Disable Wi-Fi during sleep" from the "Sleep Settings" window of Sleep Aid.
- Select "Disable Bluetooth during sleep" from the "Sleep Settings" window of Sleep Aid.
