Why does the bios/firmware have no safeguard against this? Imagine a rogue program or virus damaging your hardware, even on OS X. Also, the headline is jumping to conclusions, this is what the poster wrote: " It is unclear what the source is, but most people are suspecting the deprecated audio driver on Windows."

Well, that makes up for an interesting ransomware - you have 48h to pay up 4 btc or your shiny new mbp hardware will get borked.

I have to imagine that any self-respecting author would use '1812 Overture' just for style points.

I think I am starting to get worried about the future of Apple. 2016 was a bad year. New iPhone has been the worst selling one in relative numbers since the iPhone. New MacBooks has several issues and controversial choices, while not bringing anything substantial to the table. New Watch changes are so small, nobody noticed an update.

It's not really a secret unfortunately:

New iPhone 7 Data Suggests Sales Slower Than iPhone 6S - http://www.forbes.com/sites/ewanspence/2016/10/03/iphone-7-s...

[edit] You have actually more data here: https://www.statista.com/statistics/263401/global-apple-ipho...

If you compare 2016 Q4 to 2015 Q4, iPhone sales are retracting. Same for 2016 Q3 against 2015 Q3. I don't get what the debate is. It's public data.

Is there a possibility of happening this to headphone connected to Macbook Pro? Can that damage my ears due to loud sound?

Even with a properly functioning Macbook or iPhone, you can damage your ears if the volume is too high. In the EU, there are limits to how high you can turn up the volume in an attempt to prevent this.

Earlier quoted context omitted.

See, I'm the opposite. I always wanted the headphone jack on the bottom because that's where it needs to be for the phone to go properly in my pocket.

If screen rotation were free, surely you could both have what you want?

Problem is that the camera is on top so if you rotate the phone and stand the phone on a surface, the camera is pointing in the wrong place.

That is a very different situation than "New iPhone has been the worst selling one in relative numbers since the iPhone."

I remember Dell laptops also had speakers permanently damaged, they blamed VLC software for that. https://news.ycombinator.com/item?id=7205759

That was three year old post. What is the status now? I know VLC allows playing 400% of original volume, and their cheap speakers cannot handle it. But Macbook Pro is an premium laptop. It should not be happening.

Even if at 400% volume the hardware shouldn't let through as much power as to blow the speakers. The waveform should be amplified and clipped to a safe value. The same applies to this Mac. If they know the sound chip can be tricked to send too much power, fix the sound chip or pick another one. If they didn't know, they didn't test their product.

Your (good) headphones most likely have a hardware limiter that prevents them for blowing up (of course there are exceptions I know)

New MacBooks has several issues and controversial choices, while not bringing anything substantial to the table. New Watch changes are so small, nobody noticed an update.

I'm also worried. At first, I rationalized weakness on the Mac front as a side-effect of a strategic prioritization of the mobile & cloud ecosystem. But then I got the new iPhone, and I've been surprised by my emotional reaction to it feeling buggy. It's all relatively minor in isolation; voicemail consistently fails to load messages multiple times before it succeeds, voicemail occasionally crashes, apps get stuck ha…

> cloud ecosystem.

Apart from promoting the the App Store, has Apple done anything to promote or enhance it's cloud offerings? I don't recall hearing anything about iCloud in a very long time.

> voicemail consistently fails to load messages

AT&T? I've noticed this to be the case for AT&T users regardless of whether it's iOS or Android. Their visual voicemail is unreliable.

> or me fat-thumbing an interface

I routinely run into issues trying to use iOS on iPhone 5/SE test devices for work. The touch targets are so small I have cock my fingers at weird angles to be able to hit buttons. The App Store purchase buttons are some of the worst offenders. It's almost like Apple stopped testing their UI on small screens after the iPhone 6 came out.

For the record, if the speaker is truly blown (ruined) this is a problem with the hardware - not the software. If you can't design a speaker and amplifier combination with a limiter that won't let itself self-destruct, you are an audio design failure.

I mostly agree on this, but I can also see how they got to a design that has this flaw. You can do better (more transparent, more adaptive, etc.) limiting in DSP than with a simple hardware circuit. Doing the limiting in the driver also saves you hardware components and PCB layout space. It's a slippery slope of optimization that only works when you control the OS (or drivers at least) and the hardware together, but…

A small micro or DSP processor can sit in the data path and solve this problem "in software, in hardware". It's unusual for software to be able to damage hardware for a consumer product.
