+
+After upgrading to macOS Monterey, my screen kept lighting up in the middle of the night for no apparent reason. It had
+happened before, but only when notifications came in. Now the screen lights up on its own with no trigger — same
+hardware, so it must be a software issue.
+
+After searching online, I first
+found [Apple's official guide](https://support.apple.com/en-gb/guide/mac-help/mchlp2995/mac). It's very detailed, but
+clearly of no help whatsoever.
+
+Digging deeper, I found the root cause. Run **`pmset -g log | grep DarkWake`** and you'll see your Mac hasn't been
+resting while you slept...
+
+Several typical patterns appear, most with a DarkWake immediately followed by a Wake. The issue: DarkWake is meant to
+wake the computer in the background to update data, but somehow a peripheral gets triggered, causing a full system wake.
+
+In any case, I don't want this feature — Power Nap. For me, I'd rather it save as much power as possible. The fix path:
+disable network access wake, disable Power Nap... But here's the catch — on M1 devices, there is no Power Nap option in
+settings. (Clearly, Apple is confident in their battery life but overlooked the power of bugs.)
+
+So for Power Nap, we have to go through the command line. First, check the current status with **`pmset -g`**. Find the
+**`powernap`** value — if it isn't 0, it's enabled. Disable it with **`sudo pmset -a powernap 0`**.
+
+Also check **`tcpkeepalive`** — it likely isn't 0 either and should also be turned off. It controls whether your Mac
+maintains TCP connections while sleeping. Run **`sudo pmset -a tcpkeepalive 0`** — you'll see a terminal warning:
+***Warning: This option disables TCP Keep Alive mechanism when system is sleeping. This will result in some critical
+features like 'Find My Mac' not to function properly.***
+
+Essentially, turning it off limits some features — the system simply won't connect to the network while asleep. I'm
+fairly confident that if someone actually steals your Mac, they won't be getting it online anyway.
