When I open the lid of the mac it takes maybe 20-30 seconds to resume. I consider this a small price to pay in exchange for reliable sleep and less battery drain with the lid closed.
If you want to try this, run in the terminal:
sudo pmset -a hibernatemode 25
If you don't like it, you can restore defaults with:
sudo pmset -a hibernatemode 3

Edit 2: My bad, I assumed power nap == "wake for network access". This no longer seems to be an option in macOS 26. Mine's set to "Only on Power Adapter", which makes sense. Edit: On an M4 MacBook Air running macOS 26 DB
> sudo pmset -a powernap 1
-a is an option to set it for battery and plugged-in. If you want only either you can do -b for battery, -c for charger
You can also check the settings with:
> pmset -g
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…
Turn off WiFi when going to sleep, turn it back on on wake.
I don't need my laptop to be doing things when it's in my bag. It's not a phone, unlike what Apple seems to think...
Apple's power management isn't as great as everyone claims. I've an older MacBook Air with a severe battery drain problem. The battery will last maybe a day or two when SHUT DOWN (not sleep) before being fully drained and refuses to power on. It's done this since day one. I tried resetting everything possible which could be reset and nothing helped. Allegedly the problem is related to a Bluetooth radio which does not…
I haven't used a MacBook in years but when I did, their power management was actually the worst thing about them - this was before they moved to ARM, so I assume it has improved, but it was common for a MacBook pro to turn into a screaming hot chunk of aluminum which would burn your legs on contact and misrepresent the actual battery life available to it.
could they have used larger fans to reduce that noise? yes, definitely, and probably should have. but it's hard to beat using the whole device as a radiator.

Like, "Intel older"? Those had terrible thermal management for a laptop. An "older" laptop with a dead battery or one misreporting is not uncommon and has no bearing on how modern laptops, be they from Dell, HP, or Apple, perform. You could have 500+ cycles on any laptop and see the behavior you're claiming is terrible power management. https://support.apple.com/en-us/102888 Get a semi-new Apple laptop and then let u…
So your solution to Apple's terrible power management is to give them even more of my money?
As I said, it did this since it was brand new. Battery cycles have nothing to do with it. It's a macOS or hardware problem in the SMC.

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.
> 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. It's actually not. As a user I'd expect the device to wake up and still have the same IP address via a continuation of the lease. Yes, the correct way would be a longer lived DHCP lease, but el-cheapo ISP routers often lock down such settings.

Interesting, as a different user, I'd expect the opposite: If my computer is "asleep" I don't expect it to do anything, and it shouldn't be able to wake itself up.
