Hardware Requirements For Sierra Mac Os
OS X has dropped support for MacBooks and iMacs older than Late 2009 and MacBook Airs, MacBook Pros, Mac Minis, and Mac Pros older than 2010. IOS has dropped support for the iPhone 4s, iPad 2nd and 3rd gen, iPad Mini 1st gen, and iPod Touch 5th gen. Mac mini (2010 and later) Mac Pro (2010 and later) macOS Sierra system requirements are also available in this support document. It’s interesting that macOS Sierra marks the first time Apple has changed the system requirements for the Mac operating system 2012’s release of Mountain Lion.

Bluetooth is the perfect example for this. It's a fantastic carrier for features like Continuity, keyboards and mice, and audio. However, any Mac made before mid-2011 (and quite a few after, until they were all upgraded) is guaranteed to have Bluetooth 2.1. This older version is only slightly faster than USB 1.1, and it's a big bag of hurt with battery life. That's not enough speed to handle Continuity features like phone calls on your Mac, or make efficient use of Magic Keyboard's tiny battery. It was also terrible for stereo audio quality.
Bluetooth 4.1 is much better at handling these things. Diminishing returns, mainly. As you strip away features from macOS, it becomes less and less useful to the user. At some point, it's better for the user to simply stick with the OS they have than to upgrade. Also, there's planned obsolescence. The idea that Apple doesn't make any money if this product lasts forever. They declare it officially 'obsolete' at some point so that you'll buy a new one.
Now to what degree Apple employs this strategy is unknown, but it's a safe bet to say that it is happening. The bit where 2002 XP era machines run Windows 10 better than they did with Windows XP.
The bit that y'all are forgetting is that Windows and Linux distros work on older machines, so it's no excuse if Apple refuse to do the same. And I say refuse because whilst one could argue that MS have the better and bigger software team (as MS is a software company at its core, not hardware like Apple), Apple have more people and better people working for them than the volunteer open sourcers working on Linux distros and kernel. Yeah that's definitely not a thing that's in any way common. Trying to get Vista machines running Windows 10 smoothly can be a struggle. And it's not like Apple's vendors will work with them on drivers forever, and they have far better things to do at Apple than write drivers and tweak modern software for increasingly older machines. I mean, where does one draw the line?
It has to be drawn somewhere and Apple drew it pretty reasonably here. There's also the accounting perspective. The way these free software upgrades work is not compile the gold master and upload it to the CDN. It's not just that they're giving something away for free. Every unit getting the new software has to be accounted for in a specific method because the original OS was factored into the cost of the machine, considered a product component, and you're replacing it/augmenting it. (The Apple 10-K can explain this better than I.) • • • • •.
