Sleep issues in Sonoma

[maccan]

What surprises me about this is... Apple have been making OS X for over 20 years. You'd think there would be some institutional memory that would cause engineering management to not greenlight a new thing (CSPN) that unconditionally wakes the Mac every hour, and isn't configurable in System Settings, because it would be known that that would annoy users in a bunch of scenarios.

There's currently a lack of adult supervision in the MacOS development team I guess!

The problem may be related to all the mobile devices (iPhones, iWatches etc) constantly communicating with the Mac as a central hub. If you have turned Bluetooth and WiFi on, it is difficult to precisely define when the machine should wake up and under what circumstances it should do so. On my desktop machine I'm using wired Ethernet for the main communication line as my workflow allows this. So I can comfortably switch off BT and WiFi. Together with some tweaks discussed in this forum it is possible to setup a proper sleep (as long as you wish, without a single wakeup switching on all peripherals). But of course depending on peoples workflow, this might not be an option. What Apple should implement is a simple switch, which when turned on puts the Mac to REAL sleep.

Just discovered this bug on two Mac’s of mine. Been using the app Sleep Aid to tweak and track sleep sessions. My mac is up every few seconds or minutes throughout the night. Definitely seems to be a Sonoma issue. I took my mac to the Apple Store and they wiped it and I started it fresh. Still has this issue, I doubt it’s hardware.

Often it will start up immediately after sleeping. I will have to try this solution later.

I've been battling external HD insomnia for years, now as of 14.5 the whole system (iMac i9) won't go to sleep without manual intervention. According to Terminal, BTStack and Handoff are the culprits.

^ Mac seems to be sleeping again with 14.6.1, though I don't expect a HD fix after all these years.

Yeah, the HD-Sleep-Bug has come to stay.

It's probably no coincidence that I've been having difficulty waking my external display ever since the 14.6.1 update. Mac not sleeping was a persistent problem of mine for years. Then for a few years, external screen not waking was the problem.

Every now and then I have bliss and everything works. I probably had the longest stretch of problem free sleep-waking that just got broken by 14.6.1. Now I'm back to the screen not always waking. Ugh.

Also can confirm that HDs waking up is still an issue. Disabling "Put HD to sleep when possible" yet again.
