Mac OS X

When users attempt to launch a 32-bit app in 10.13.4, it will still launch, but it will do so with a warning message notifying the user that the app will eventually not be compatible with the operating system unless it is updated. This follows the same approach that Apple took with iOS, which completed its sunset of 32-bit app support with iOS 11 last fall.

This is good. I would prefer other companies, too, take a more aggressive approach towards deprecating outdated technology in consumer technology.

fmaxwell,

That's like contending that x86 Linux binaries should run on x86 Windows computers because they use the same hardware "technology."


Or, to stick with your analogy: a car stereo manufacturer choosing to support MP3 & WMA, but not OGG.

I'm not sure if you knew this but MS actually does support Linux binaries on Windows 10:

This is about the OS, not the CPU. It's about Apple deciding to retire a lot of code in their OS by dumping support for 32 bit apps.


Yes, exactly. Obviously the hardware still supports 32bit code.

You can talk in vague terms about how things are "largely the same technology," but the 32 bit apps can't run any more and it's not because Apple incorporated something in their OS to block execution of 32 bit apps that would otherwise run without a problem.


Hypothetically users could provide their own 32bit libraries even if apple does not, however this could only work if apple did not take steps to block 32bit software from the application loader.


IMHO there is a more fundamental problem for users than 32bit versus 64bit, which is being dependent on proprietary software that cannot be updated/ported to new architectures in the first place.


P.S. Thanks for the link, but I've been developing in assembly since 1980.


Awesome, I'm always happy to meet other assemblers ;)
