For those without spacebar heating?

They broke that workflow in a recent update. Software these days is horrendous

How big is the risk of condensation when you bring a cold laptop inside?
replyAll their spec sheets say they support up to x% _non-condensing_ humidity, which I’m guessing is about the dew point?

The uncomfortable fact about the mentioned Wisconsin winters is that inside dew point tends to be quite low.

For years at work I've been just using Cinebench as a hand warmer on various Macbooks.

I think my last Macbook was Wisconsin-locale instead of California. Closing the lid and putting it to sleep actually caused it to heat up (until the battery died).

Alternatively, you could try compiling an Xcode project. That should do the trick as well.

Or you could get a laptop that doesn't have an metal shell, like a thinkpad.

Needs 2019 in title, this is Intel MacBooks not Apple Silicon.

I've found that Baldur's Gate 3 will warm up my apple silicon (everyday tasks do not).

Is that running on Rosetta 2? Rosetta 2 does (or did, maybe it's removed now) a fine job running x86 code on Apple Silicon, but boy was it cycle-hungry to do it.

Apple Silicon is not really the simultaneously silent and quiet and cool system it was in the M1 days.
replyIf you get a MacBook Air it will get quite toasty at throttling limits. After all, it has no fan.
MacBook Pro models and Apple computers in general tend to favor quiet operation over keeping the laptop surface cool.
Many PC gaming laptops go out of their way to keep warm air off the keyboard deck with a high willingness to use fan noise to accomplish that since the assumption is that you’re resting your hands on the computer for an extended period and you have headphones on for your game anyway.

From what I've seen in a couple of videos the newest Neo crap can get to 100 degrees Celsius.
replyrogerrogerr 4 hours ago
The target market of the "Neo crap" doesn't care and/or isn't pushing workloads that come anywhere near saturating it. It's a laptop that doesn't bend, has a decent screen, has a decent battery, and isn't full of adware.

The article was about warming up a laptop. Neo can do it too.
replyrogerrogerr 3 hours ago
And your comment was calling it crap for some reason. We wouldn’t be having this conversation if you’d left that apparently superfluous word out of your comment.

How does the Neo getting to 100°C make it crap? By that logic, aren't all older Intel/x86 chips crap? If anything, I find it impressive that a small laptop CPU can do 100°C without a problem...my i7-7700T M710qs hit 75°C and throttle within a minute if I use a tool like y-cruncher or stress-ng. To be fair, totally different purpose.

Won't work on M processors, (un)fortunately.

I left my Mac Studio running at 100% CPU on all cores for 14 hours, and the case ended up noticeably warm to the touch. It is possible!

I recently installed an app to manually activate the fans on my MacBook Pro M1 Pro as I've never been able to trigger them over the past 4+ years. Just to check whether the fans even work (they do).

You must be using only lame languages like C or Go or Python that aren’t optimized for laptop warming during compilation. Try using a Real Language with a Real Compiler, like C++ or Rust or Swift, and build decent-sized projects using all cores.
reply(All joking aside, this is why I have a MacBook Pro. Compilation easily hits the Air’s thermal limits and the performance boost on the Pro with its fan is impressive.)

You could also build Chromium from source. It makes my M1 Max's fans sing.

Honestly m1 was very cool no matter what workload you threw at it but at this point m4 max does get pretty hot even with just web browsing.
replygpm 5 hours ago
I've definitely had my m1 air get uncomfortably hot to touch - particularly right above the keyboard. (While doing developery things)
replyinventor7777 2 hours ago
Can't say I've ever thought of a word like "developery", but now that I've seen it I like it a lot :-)
