That would let me run a 60-90 minute video conference without troubles.
The only redeeming feature of these machines is that they could emulate old x86 hardware at speed. That allowed me to run old apps on old OSes without having to keep old hardware running.
they're doing what to my CPU????
All their spec sheets say they support up to x% _non-condensing_ humidity, which I’m guessing is about the dew point?
yes yes(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.)
Also, pour one for the death of the analog speedo. Peg the needle, no more!
My M3 Macbook Pro's palm rests get uncomfortably warm during regular IDE use. It doesn't get hot enough to spin up a fan, but it is enough to be distracting.
If 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.
yes > /dev/null&Found a web based benchmark tool that will run your CPU and GPU at 100% each. While temperatures went up to 90 degrees science... still no fans. Ended up installing a different utility to manually set the fan speed to confirm they worked.
I don't know what they did but it's good.

You’ve been there - after putting your backpack in a frigid car, walking against the Wisconsin wind, or biking across the frozen lake, you arrive at work. You rest your palms on the keyboard to begin typing your password, and recoil in pain from the sudden cold of the metal sucking the heat from your skin.
How do you quickly warm up a laptop? Make it do a lot of work.
Here’s a one-line, built-in command that will peg your CPU to 100%:
yes > /dev/null
Run that from a Terminal, and don’t forget about it heh. What the command does is repeatedly send the word yes over and over to the null device, using 100% CPU.
If you want to stress your Mac more quickly and get your CPU hotter, try the stress utility:
brew install stress
stress -c 6 -m 2 -t 300
This will start 6 threads that each peg your CPU to 100% and 2 thread that do memory malloc/free. It has a 300-second timeout (5 mins) in case you walk away from your computer so it doesn’t overheat.
Bonus points, you can add an alias to your ~/.bash-profile to automate these options:
alias warm='stress -c 6 -m 2 -t 300'
fred: bash$ warm
stress: info: [65121] dispatching hogs: 6 cpu, 0 io, 2 vm, 0 hdd
Happy winter!
This applies to any computer, Apple, Windows or Linux. Desktop or laptop.
If your typing on any computer is dependent on you resting your wrists whilst typing then it is indicative of poor typing technique and/or posture.
And ironically the very thing you think you're trying to prevent by resting your wrists (carpel tunnel and/or strain) is likely to be aggravated by over-reliance on wrist wrests due to the added pressure on the wrist.
My i9 2019 MBP with discrete graphics was probably the worst laptop purchase I ever made. Docking it to an external monitor would enable the GPU, so even when idling it would run the fans and drain the battery.
I’d read cautionary tales about Windows laptops being pulled out of backpacks scorching hot as they failed to shut down. But that happened to my Mac all the time, too.
The M series though is incredible. I can’t imagine buying a Windows laptop now.
Installed Linux mint Xfce Edition for lightness, installed ollama, start to test different models. Gemma4 e4b runs perfectly fine, exposed it to the network, connected to it with my current notebook and use vs code codex to start to run inference.
For about 30 minutes of bliss, this setup work at a reasonable speed... then the MBP shut it self down. It was so hot that it trigger the safety mechanism, the fans sounded like the laptop was about to take off.
I though on leaving it on inside the fridge, but then the WIFI wouldn't reach.
On the other hand, my wife saw all this and offer to buy me an M5... the experiment didn't work as intended, but it did work.

I think the real question is what IDE we're talking about.
It's not hot, but with 22C ambient it is enough of a rise to be annoying.
Electrolytic capacitors can freeze up but again, you'd need a Yakutia-like environment for it to actually pose a concern.
Lastly I've heard of circuit boards warping from going from really cold to really hot, but those were power components.
So overall it’s not something I’d worry about.
So every time you do HTTP calls? Nothing there should spin up your fans, unless you use an agent with an horribly broken TUI, I've heard there is a few of those out there. But remotely calling LLM APIs really shouldn't be taxing on your local device, something somewhere is wrong/bad if that's what you're seeing.
Intel really made themselves unpopular with Apple during that period.
The other issue is that unless the battery has been replaced relatively recently its charging efficiency may not be that great and the high load being placed on it might be causing it to get hotter than it would have done when new.
I had (and still have) a 4k external monitor. Naturally I wanted the MBP to drive the monitor with a resolution that took advantage of all the pixels. Unfortunately with most monitor settings the GPU power consumption would produce enough heat to run the fans even if the rest of the system was completely idle! If I set the output to full HD the GPU would cool down and the fans would turn off. But full HD on a 4k monitor is a waste.
It was very strange. I could drive the monitor at 4k but with the image upside down, and the power consumption would be low. But flip the image right side up and it would run hot and turn on the fans.
It took a couple weeks of fiddling, but I finally found a combination of refresh rate, resolution, image orientation (right side up!), and cabling that let me drive the monitor at high resolution without running the fans. What a pain.
(I used iStat menus to monitor GPU power consumption. At “good” settings it consumed about 5w. At “bad” settings it would consume 17w. At a bad setting you could immediately see the various temperatures go up and the fans spinning up to compensate.)
Hold my beer. I'm going to run Qwen on this 3rd-generation iPod... somewhere my partner can see
hahaha
You can't tell me that this wasn't known by Apple before shipping the product. Why did they not provide adequate cooling for the CPU?
Intel just reenacted IBM's history with Apple, particularly the G5 era. That CPU was instantly a no-go for anything mobile. In workstations it was cranked ever higher with very poor power-frequency scaling, needing water cooling for the beastly 200W idle power consumption and close to 1kW full throttle.
That went well so was a perfect role model for Intel's i9.
I presume Apple knew perfectly well but wanted the halo product to sell to those people who will always pay extra for the perceived “top of the line” product. Once Intel branding had created an i9 that was a bigger number than an i7, then Apple was going to sell it.
It was faster than the i7 after all: just not for very long!
My entirely speculative theory is that the poor thermal characteristics of that era of Intel CPUs didn’t really become apparent until quite late in the development process & by that point Apple had probably committed to buying a fair chunk of Intel’s output.
I spend 95% of the time with just PHPStorm and other stuff like the terminal, slack and ticketing open. And the browser of course (safari). Xcode and Android Studio are rarely opened. Mostly when I want to test out something in the apps that isn't on testflight / firebase yet.
