There isn't anything wrong here. One of the confusing issues is that people say, "I'm only using 15% of my CPU, the fans should not be coming on." What they don't realize, is that using 1 core running at turbo speeds is only going to show up as 15% of the CPU, but draw enough power and create enough heat to trigger the fans! Another thing that some of these posters are not aware of, is that running these temperature/…

macOS reports utilization normalized to a single core. 25% means 25% of a single core. Full utilization is displayed as 1600%.

I have a 2011 here still going strong. Looking like new after all of the free replacements, LOL. I guess that GPU either fried over and over by now or came from a lucky batch.

Mine collected dust for almost 2 years until they announced the repair program. It came too late. I ended up giving it to a junior dev which used it for another year before dying again.

I think we replaced the battery for free or cheap and the screen was in the lamination program, the GPU is the same one as day one. Isn't it weird that it just never happens to some people and other people keep getting their GPU's fried??

macOS (Activity Monitor) reports utilization normalized to a single core, so 15% really means 15% of a single core. On the MBP the scale goes up to 1600%.

I set some fairly short term and trivially verifiable predictions. Save this comment and come back to it at the end of this year. Unless Apple's AR play succeeds, they're going to be left in the dust by Chinese offerings with better functionality at half the price. Cook has had the better part of the decade to come up with something new, and has failed to deliver anything except incremental minor updates which are in…

Are you just going to pretend the AirPods and Apple Watch don’t exist? By themselves they’d be a Fortune 500 company. “Minor updates”. You have to be joking.

Are you going to pretend either AirPods or Apple Watch are meaningfully competitive against other offerings on the market?

There are headphones with better spec than airpods at half the price available right now. They're not locked to any ecosystem. Apple has no idea how to continue competing in the envelope of modern hardware because competitors either beat them or match them on every move but without the premium.

Save my comment. Check back in a year. It'll be a good lesson.

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…

Summoning all of your experience as "a person somewhat close to electronics engineering", you deliver this gem: > I simply don't see any signs of proper thermal engineering here. I hope you're joking. If not, you have a nauseating level of conceit.

I appreciate his remark. He should pop open Asus machines and make videos of himself criticizing them, conceit and all.

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…

> How can we move forward using Apple? And why should they? What's wrong with trying out something like Thinkpad X series[1] instead? Or Thinkpad P series, which can now come with Ubuntu LTS pre-installed. I wonder, if they would have invested so much time in fixing Dell's issues for Dell. Probably not. Why? Because there is no Dell's lock-in. [1] https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-x/c/t...

I have a SAAS that uses video chat for medical professionals and the #1 creator of support tickets for video problems are those with Lenovo. In fact, when someone has an audio of video problem, “Is this a Lenovo” is among the first questions we ask. The people who have the fewest technical issues? Mac users.

A single anecdote, of course, but advice to switch to Linux is naïve. Most people aren’t software developers. Many people use their computers for things like graphic design or media editing. How do you run Final Cut or Logic on Lenovo with Linux? How about Photoshop? MacOS and Apple hardware is superior for a wide variety of use cases. Maybe not yours, but for many people the pluses of Apple far outweigh the minuses.

I’ll tell you one reason why you shouldn’t switch to a Lenovo laptop: their atrocious history with backdoors and buggy, vulnerable software, and the lockdown within their BIOS/UEFI to prevent things like swapping components for no good reason. Ok well, that was more than one reason, but you get the drift.

That's not true for Lenovo Thinkpads, which is a separate business division from Lenovo consumer hardware, as far as I am aware. And subsidizing consumer hardware with spyware has, unfortunately, become a standard industry practice. Most smartphone and Smart TV manufacturers are shipping their consumer devices full of bloatware that is extremely hard to get rid of.

Not at Apple.

This is a bug on Macbooks in general, as I understand it. I have a 2019 MBP with a 4k monitor, and if I change the resolution to anything except the default, there is massive system-wide lag. God forbid I use PyCharm on 4k scaled resolution – a full second between typing and seeing the text.

That seems unrelated; I think Mac OS is the only place where non native resolutions use GPU-accelerated scaling. The other operating systems just set whatever resolution you asked for and let the monitor handle it. This seems to be excessive GPU use when simply connecting an external monitor at its native res.

Also, at least macOS provides a consistent resolution for windows, texts, etc. On Windows (after Win 8), many times old applications run with __blurred__ texts and icons while the new shiny Win apps have no such problem. It's actually one of the reasons I don't use Windows anymore, although it's been making good progress.

Been using Mac primarily since 2011 and sad to see everything keep declining with Apple's software and hardware quality. When programming an app and its backend with react native/clojure my 2015 Mac Pro gets way too hot and slow. Just built a Ryzen 3600 desktop with 32 gigs of RAM for about 1/4th the price as the cheapest 16 inch Macbook. Windows with WSL2 has been extremely good and I'm satisfied with my development…

I second this. For $2000 I built an absolute monster of a desktop PC. Super fast, never an issue and I use it for everything. I only use my MacBook when I wanna sit on the couch and that's it. Thankfully I got my laptop through work almost for free because it wouldn't have been worth the money.

HN users can't tell the difference between a laptop and a desktop apparently.

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…

wow, a few years ago i was working in java world, and using intellij on a daily basis. any time i used a 4k monitor, i simply could not type anything or scroll through code without insane delay. i googled it and found a ton of people having the same issue. i could only sanely use intellij if i upscaled my resolution to its highest. is this all interconnected?
