Please take this gently, but I did not really walk away from this post having gained anything. I don't have any problems with the post in isolation but I just don't feel it really offers enough weight to be here if that makes sense.

I read a few of your other posts and your writing style is direct and pleasant in a way I appreciate. Thank you for actually writing things.

Then my comment won't help you much: since I swapped my MacBook Air M1's 27" monitor for a 34" one from the same brand, it's only been the exact clusterfuck of unreliable "wake up not working properly anymore" for no friggin' reason. Except in my case it was working fine, and now it's not anymore.

The author does not call it out, but I think the point is that it's not only the dock. I've been struggling with MBP wakeup issues for a while. We have a whole zoo of various apple devices attached to a number of docks. All of the monitors are Odyssey Neo G9. TL:DR an issue with MBP port, MBP to Dock link, Dock, Dock to Monitor link, or the monitor itself could cause the unplugging dance.

In addition, it takes some time for Apple to squash bugs after releasing new hardware or software. M5s used to be unreliable with Anker TB4 until 1-2 months ago.

Us old people have the idea of peripherals as input (keyboard, mouse) or output (monitor, printer) - but they've all been input/output for two decades or more; and Thunderbolt and friends are much more like an Ethernet network (reliability of Wake on LAN, anyone?) than they are simple point-to-point connections.

Meaning - anything could be the device preventing what you expect to happen, even if it looks like it should be impossible and have nothing to do with it.

HDMI CEC is the bane of my (home theater) existence.

Which device just woke every other device up at 4am?

Which device just shut everything down while I was in the middle of a movie?

And are they the same device?

A Raspberry Pi can help debug and fix HDMI CEC flakiness, with the right cable - https://johnlian.net/posts/hdmi-cec/

CEC and eARC piss me off to no end - it was all working perfectly for over a year and now the receiver refuses to cooperate (or maybe it's the TV, who knows) and you have to cycle things by hand like a meanderthal.

I struggled with a dock and a MBP and connecting consistently to a monitor. It was a high-quality USB-C to HDMI cable. I was sure it wasn't that.

Turns out it was that.

I’m hoping the comments will have a better insight into what’s happening

No idea how this made it to the front page. HN is not tech support.
