What can I say as a person somewhat close to electronics engineering: Look at that single skinny heat pipe, it will get saturated very fast. Second to that, look at those tiny radiators, they are clearly not capable to discharge the full heat flux. I simply don't see any signs of proper thermal engineering there. Apple says "we are listening now, and here is a new cooling design," then it comes out to be even less ad…

> Apple says "we are listening now, and here is a new cooling design," They also keep at "oh, look how thin it is" even though the vast majority of people stopped caring 5-7 years ago. Make it thicker, but with better cooling, better storage, better GPUs etc. Worse still, they do it across the line. "We painted ourselves into a thermal corner with MacPro" says Apple and keeps releasing iMacs (and iMacs Pro) with seal…

They literally did all of that in 16 inch.

If I had to guess they know what they're doing engineering wise, but they're taking a calculated (and poorly thought out, in my opinion) risk that a small percent of people will regularly peg the cpu at 100% usage, and they're further relying upon clock rate throttling and the cpu die thermal sensor to keep things from melting down. Or the management/product design group has overridden the input of the people who act…

That's why I buy gaming laptops for my work needs even though I don't play games. Their heatsinks are generously sized resulting in good thermals and acoustics.

I use a similar trick: I try to find a laptop that comes in both discrete-GPU and integrated-GPU configurations, and both version must share the identical chassis.

This way, when I buy the integrated version, I know the chassis has been designed with the heavier airflow of the discrete-GPU version in mind. If I'm lucky, my integrated-GPU config might even use the identical size heat-sinks as the discrete-GPU version.

I was planning to buy MacBook 16-inch as I am still on 2014 edition which in my view were one of the best MacBooks. I simply hate that unnecessary Touch Bar, was hoping Apple will remove it but didn’t. Thought then of getting 16-inch as they have an esc key. Waiting for this kind of review, I will put on hold purchasing it until get a clarity on fan noise. My current old MacBook fan do make some noise but only under…

I've got a new MBP (from work) and an x1 yoga personally. The X1's running Linux and frankly works beautifully. The mac's "quirks" aren't counterbalanaced anymore by being the only reasonable unix laptop solution. They're just an annoying PITA.

The Yoga is nice, I have one too, but there was no option to add a dedicated video card, and this issue with the MBP always seems to stem from the dedicated cards.

The thermal design of Macbook pros just isn't adequate for >4 core high clock speed CPUs, especially with a discrete GPU thrown in the mix too. I had one of those i9 2018 MBPros and it was always super hot. Much happier now with a 13" 4 core MBpro, it runs quite cool and without any fan noise most of the time. Built a separate AMD 3900x PC with an Nvidia GPU for heavy lifting, and can use that remotely with the MBpro…

These problems are not new or only affecting MacBooks. I had a 27" iMac for work and it cooked the display panel, HDD and the discrete graphics card. I did drive the system, including the GPU, reasonably hard, but nothing exceptional. To Apple's credit, they did replace the HDD and the display panel for free, but when the graphics card died I just gave up on it.

It seems like the combination of the form factor, components and thermal solutions that Apple uses just don't add up.

I wish someone would publish a guide for MacBooks based on palm rest idle temperature, having a hot sweaty palmrest (especially in warmer climates) bugs me more than having a bit of fan noise and if it was clear and transparent maybe Apple would design better thermal solutions.

I have MBP 16" with the 8-core i9, palm rest sensors show they are at 32C and 30C at my regular usage (browser, IDE, slack and other apps). However i don't use external screen.

I waited multiple years to upgrade from a MacBook Pro 2014, but was disappointed year after year, because I read about heating issues, the bad butterfly keyboard or the useless touch-bar.

In 2019 I felt like things are not going to get any better, so I bought a MacBook Pro 2019. Was quite unhappy that I didn’t wait a bit longer after I saw the 16inch version coming out a few months later, because it had an escape key (which I really miss on mine), but now I am kind of happy that I have the 2019 15 inch version where the heating problem does not appear.

The touch-bar really is completely useless, I find myself tapping the wrong "keys" all the time. Changing volume was so easy before, now it became really hard. But most of all I miss the escape key. If it wasn’t for macOS I had long picked a Windows laptop.

What's disturbing is that Apple seem to be deleting posts: After attempting to be part of the solution; spending a ton of time testing, providing information in the community, communicating with Apple Engineers and Apple Business Team, our most recent post was deleted as "Speculative". We have spent over $300,000 on Apple hardware over the years both business and consumer and now our voice has been muted. How can we…

I was going to ask where that quote was from before realizing that there is a 44-page thread beyond the two highlighted responses.

I went from late 2013 13 inch to the 2016 16 inch (maxed everything but the graphics). I also hate the touchbar. Things like volume control that used to be a tap away are now hidden in sub screens. You can switch it to only function keys but they are missing the icons for volume etc and you can't touch feel where the buttons are so I have left it in full touchbar mode. Some functions of it are actually quite cool but…

Tweaks like Goldenchaos can help with usability. Volume control becomes a 2-finger slide on the touchbar. It’s not ideal, but it’s certainly better than nothing.

You can tweak the touch bar to put e.g. volume control on the 'home screen' if you prefer; it's hard to find though, it's under Keyboard, then the Customize Control Strip button at the bottom.

I just checked. Unless I'm missing something there is no simple volume control like on the physical keyboard? I already have the volume button on my touchbar home screen however tapping it opens a slider. I don't want or need a slider and have to do a tap and then slide to get the volume down whilst before it was one press of a button. This usually requires me to look away form what I'm doing. It's definitely a step back in terms of UX. It was perfect before the touchbar.

Thanks for pointing that feature out though. Have replaced Siri with the play button :)

Edit: Just playing around with this a bit more I noticed the expanded view now has all the normal icons. Either I missed it before or I changed something. Is there a way to make the expanded view the default?

This appears to be a software bug in macOS or AMD's drivers. Plugging in an external monitor at certain resolutions (1440p@60Hz in my case) will cause the AMD GPU to draw 18-20W constantly, no matter what it's doing. This causes the total system draw to increase from ~10W to ~30W. All that heat has to go somewhere. If I change the resolution of my external monitor to 1080p the AMD GPU drops to ~4W and the fans are qu…

Can you share how you're measuring GPU power draw? I have just migrated to a 16" MBP with the AMD chip, and also use an external display some of the time. Have noticed the fan noise and heat but it hasn't been a problem yet.
