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

  1. "Wake for Maintenance" is disabled on a M1 Mac.
  2. High volume of network activity is causing the Mac to wake up frequently.
  3. Apple AirTags appear to cause "Bluetooth Ache" with some M1 Macs.

Solutions

  1. Ensure "Wake for Maintenance" is selected in the "Sleep Settings" window of Sleep Aid.
  2. Deselect "Keep network connections alive" in the "Sleep Settings" window of Sleep Aid.
  3. Deselect "Wake for network access" in the "Sleep Settings" window of Sleep Aid.
  4. Select "Disable Wi-Fi during sleep" from the "Sleep Settings" window of Sleep Aid.
  5. Select "Disable Bluetooth during sleep" from the "Sleep Settings" window of Sleep Aid.
