Sleep Aid is designed to reveal details on how a Mac sleeps. This is useful to see what’s going on, and to help troubleshoot why a Mac won’t go to sleep (even with lid closed), or why it keeps waking in the middle of the night. Sleep Aid includes many Apple sleep settings, as well as some exclusive functionality, which can help solve sleep problems, increase a Mac’s battery life, and even help to protect your Mac from sniffing devices.

Neurons (artificially coloured) in the hippocampus play a part in learning and memory.Credit: Cell Applications Inc/Science Photo Library A crucial brain signal linked to long-term memory falters in rats when they are deprived of sleep — which might help to explain why poor sleep disrupts memory formation1.

“Hello Sleep” author Jade Wu, PhD, explains why waking up at the same time every day can help you sleep better at night and feel more rested in the morning.

When macOS goes to sleep, it starts a low-power ‘smart sleep’ mode which opens a network connection to see if there’s any updates. It’ll keep this behaviour up every few minutes until you wake the Mac. This is a sleepwatcher script to make it turn off Wi-Fi power (and thus disconnect you from the internet) and tell you exactly what it’s doing (the ‘verbose’ tag), then running it again to turn Wi-Fi back on. When using IRC, this prevents all the timeout/reconnects your Mac fills a channel with when it goes to sleep.

As an alternative, check to see if LaunchAgent has been added to the newest sleepwatcher brew formula. Instead, you could try brew services start sleepwatcher and then create/edit ~/.sleep and put networksetup -setairportpower Wi-Fi off in there (and chmod +x it) then perhaps create a ~/.wake if needed.
