Cook is a complete businessman, best at cutting costs, increasing profits and attracting customers to buy more. Don't forget that memory began to weld on the motherboard because this can only be replaced and not upgraded. He was a businessman, not an engineer or a designer, and that was the beginning of apple's decline.

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 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 it should exist as well as the function keys not instead of. I haven't had any of the issues described anywhere. Mine works flawlessly. Very very happy with the machine overall. A huge improvement on the 2013 mbp i came from which i agree was an excellent machine.

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.

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…

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 actually know how to design thermal solutions, because the laptop CANNOT be 2mm thicker.

Whenever I see a laptop with a >15W TDP CPU in a super slim package with a tiny heatsink/fan unit, no matter if it's from Apple or another vendor, I'm very suspicious. At least the 12 inch Macbook from a few years ago which was truly fanless uses an appropriately low powered CPU.

disclaimer: used to do systems engineering for a server manufacturer a long time ago, after you've gone through a dozen iterations of ways to mount skived copper heatsinks on dual socket motherboards in 1U cases, with various fan solutions, you realize that everything that is not acoustically terrible is some sort of compromise. People are trying to put CPU+GPU+RAM packages that are anywhere from 25W to 45W TDP in laptops that are physically too small for them.

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 quiet again. A lot more information available in this long MacRumors thread: https://forums.macrumors.com/threads/16-is-hot-noisy-with-an...
