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…

Yet again that recommended sleep aid application is a £24.00 a year subscription. I'd have paid £35 for a one off, but alas, I'll read the comments and figure it out another way. I'm so sick of subscription everything.

It's Find My. No great solution. I turn my iPad off now when not actively using it.

Another solution is just to fully turn off Wi-Fi and Bluetooth. (Not "disable new connections" but fully turn them off). I have a Shortcut on my iPad's homescreen that does this. Just keeping Bluetooh off definitely greatly improves idle battery life. And you can use Shortcut automations to automatically turn it back on when you take certain actions. And if you don't care about Find My at all, you can disable it deep…

I've been doing this with my MBA M4 since day one: I turn off Wi-Fi and Bluetooth to prevent the network and my connected keyboard and mouse from interrupting the computer's sleep.

I configured Control+Command+S as a shortcut to put the computer to sleep. While playing a music video on YouTube, I pressed the shortcut and the music stopped. However, as soon as I moved the mouse or used the keyboard, the video started playing again, even while the computer was supposedly "asleep" (with the lid open or closed).

So, at the end of the day, the best thing for me to do is turn off Wi-Fi and Bluetooth, then use the shortcut to put the device to sleep, and finally close the lid before putting the MBA in my backpack.

> I'm surprised that Apple's power management doesn't have an alert for this. I'm more surprised that any application can prevent sleep _when you close the lid_. I can understand the utility behind something like stopping sleep via timeout so a media player can tell the system "hey, they're watching a movie don't turn off even if they don't touch you for a bit". I really can't think of many valid use cases for applic…

> I'm more surprised that any application can prevent sleep _when you close the lid_. Absolutely. If my options are 1) halt the process when the lid closes or 2) let the battery die heating up the inside of my bag and then the process halts anyway when the laptop dies then please, please let me choose #1! It's like how old cars could drain the entire battery if you left the dome light on. Why would they allow that?

Maybe you really needed the dome light. Same as in this case.

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.

Whoa, I've been battling with an issue where my new M4 Mac Mini, disconnected from all peripherals, just sips power and gets rather warm overnight. Cools itself when I wake it up. I wonder if the changes suggested in the post and the comments here will help me resolve this issue. Thanks for upvoting this.

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.

Because it's fine closed? You really think this isn't a supported way of using a Macbook Pro?

Well the keyboard does stick to the screen a bit after a while, but in theory it is.

> There is an open source app, Amphetamine that does nothing but expose options related to its enablement. What does this mean?

Amphetamine is an app that allows one to keep their device running, awake, unlocked, etc. I use Amphetamine all the time, especially with agentic coding, and it’s been an essential app for me for years for other reasons (live data processing, presentations, etc.).

‘caffeinate -i ‘ No apps required

> I keep being asked if Chrome should be allowed to find devices on my network

God in heaven, how can I say yes once and for all!?!

Recently switched to macos and ios.

There are so many of these permissions I can't seem to permanently accept!

Is this a feature or a bug?

I want a button that says yes and don't ask me again. Or, no and don't ask me again.

It's like Apple doesn't trust the user.

I've worked around this problem on each mac laptop I've owned over the years by configuring "hibernate on lid close." 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 defa…

I've had to do this to my Windows laptop recently after it started completely draining the battery when going to normal sleep. Wakes up reasonably quickly still, and no power management problems!
