Computer connected to a dock with monitor is a common use case for a close lid for me.
Why not crack the lid a little? No way I'm letting the display of my very expensive laptop contact the chassis while it's in operation.
Another trick is to open Activity Monitor, switch to the Energy tab, and sort by the "Preventing sleep" column. Some apps prevent macOS from sleeping. In my case, I've discovered that Devonthink (document/notes management app) is responsible. I've been meaning to file a bug report about it. I'm surprised that Apple's power management doesn't have an alert for this. Surely an app that causes my Mac to become glowing h…
I wish ios had insights (and controls) like this. So many apps have telemetry and data collection and notifications that eat up your battery and bandwidth for business (no good) reasons.

This is a macOS bug; it doesn’t need an IP address while it’s asleep. Waking up to renew a DHCP lease is crazy. Closed source OSes are such a bane.
Macs doesn't need to wake completely to renew their DHCP leases. Bluetooth and Wi-Fi radios can act independently and on their own for this low level operations. On the other hand, I don't consider my computer to wake up, take a backup, check system/app updates and my mails and handle those while I'm sleeping as a feature, not a bug.
I can see a continuously renewed DHCP lease — with nothing else - useful for reducing the time to reconnected to your network, esp maybe on old/slow networks or routers.
You can Touch ID and get back in a second, and maybe for 5-10% of users, it was resulting in initial network connection slowdowns or errors with buggy online-only apps.
Find My (your device wants to maintain a connection if you have it enabled) is another reason. It must regularly connect (perhaps a long running socket), and I want to be able to remotely lock and wipe my device at any time possible, for example.

That is pre-Apple Silicon, before together integration of software and wakeups.

My 2014 Intel MacBook Pro has Power Nap and behaves the same when it comes to radios when compared to my M1. It's not new.
> it was resulting in initial network connection slowdowns or errors with buggy online-only apps.
Just because your radio is up, connected to the AP and keeping L2 active doesn't mean your processor/OS is keeping TCP connections up, or even talked to the hardware and updated itself. It's normal.
Find My doesn't keep a connection open 24/7. It pulls the commands the moment system wakes up. I have it enabled and check my devices sometimes, and it's not extraordinary to see "15 minutes ago" or "2 hours ago" for a laptop sitting on the table, not connected to power and its lid closed.
Anyone know of a solid Windows equivalent to Sleep Aid for diagnosing and fixing these wake/sleep ghosts?
I think I might try this setting (Prevent Wake for Maintenance)

that's called "off".
i suppose we have come to expect 4 states: - off: no power, no activity - hibernate: no power, no activity session state saved to non-volatile storage - sleep: Minimal power, RAM remains powered with the session state, can be resumed quickly - on now we essentially have sleep++ and no option to set it back to vanilla sleep.
I thought this was a solved issue. How are all OSs suddenly so bad at this? I only really trust on and off anymore.
