  One of my early mentors worked on it. They mentioned the pulsation for the sleep indicator was modeled not just on the human respiratory rate, but specifically that of a sleeping adult. It came up when we were playing around with on/off dimming curves for a room based video conferencing product and discussing physical analogies we could model a curve on. Fun afternoon exploration, but in the end we just stuck with ease-in/out. I miss when you didn’t need to overly justify taking an afternoon detour to explore whether something could be improved.

  It could absolutely be false nostalgia since I was a Mac fan from about 2005 to 2009 with an MBP that had the breathing feature but this really felt like a high point for computer hardware. It felt slick and performant but still serviceable.Ironically, after a series of uninspiring Windows machines the next laptop that made me feel any level of enthusiasm like that Mac is my current Framework 13 running COSMIC on NixOS. Quite an about face!

  That light was a big deal - I remember when I got into Arduino years ago this was one of the common projects people would do to add a breathing LED to everything, including a pumpkin:https://www.evilmadscientist.com/2010/a-pumpkin-that-sleeps-...

  This someone jogged a memory of an all-time favorite line from a 2005 laptop review (well, more of a rant than a review): https://web.archive.org/web/20090709072628/https://arstechni...> [The power] light informs the user that the X41 is on—no, really. There should be an ontological indicator next to it to let the user know the computer really exists.

  Not specifically for the Mac light, but nowadays I find it very annoying that everything as a small led light for sleep or just indicate power, or power plugged.At night it is very hard to have a dark room to sleep in small apartments or bedrooms when you have so many of them. Tv sleep lights, set top box, computers sleep and power plugged lights, small electronic devices and appliances like the one displaying time. Power multipliers that often have a safety power on light, ...

  I think the sleep light on the white plastic iBook was the first product feature I truly loved. My greatest hope is that I should be so lucky as to invent a single thing as great over the course of my lifetime.

  While I generally like physical such hardware details and lament their decline, a pulsating sleep indicator in my field of view would drive me mad.

  The dot in the "i" in "Thinkpad" on my laptop's lid does this, copying the mac, I expect. It's red, mimicking the trackpoint.

  This is a neat article.I don’t think I ever thought much about that light but now after reading this article…it really was a pretty cool and useful detail.The info about how the light’s rhythm was meant to be similar to human breathing is cool too.

  That last ~gif~ mov really looks like a sleeping robot from a Pixar movie.I think all my laptops' LEDs first blink wildly when I close them, then change to a slower rhythm, that's not an Apple feature.

  The Macbook battery indicator that's mentioned in the article, was so very good.

  The sleeping light - because what all hardware requires is blindingly bright LEDs that are always on. Even when that hardware is asleep

  In the Choose Your Own Adventure novel Supercomputer, you receive as the grand prize in a contest an AGI-capable computer and go on various adventures with its advanced thinking capabilities. One of its features is said to be a "smile light" which illuminates in a pleasing greenish color when the machine is happy. The breathing light always reminded me of Conrad's "smile light" and just went to show that Apple engineers were reading the right type of science fiction novel.

  Interesting. I grew up kinda rural seeing red "breathing lights" on radio antenna masts at night all the time way before Apple did this.Didn't seem like anything special and I always just assumed it was inspired by something like that since it's another type of indicator.
