| Look, everyone knows how Apple rolls when it comes to operating systems--they kill old APIs, frameworks, and even entire classes of apps on a pretty regular basis. No mainstream operating system that ran on 68000 processors in the 80's, PowerPC in the 90's and Intel since 2006 is even around today. Y’all must have forgot how NeXTStep, which later became Mac OS X and now macOS ran on 68000, Sparc and MIPS back in the day. The same way Apple was running Mac OS X on Intel hardware long before the first Intel Macs were released, there's got to be Arm-based MacBooks or Mac minis running macOS right now. So it makes sense for Apple to get rid of as much technical debt as they can before making that jump. And because of Catalyst, which enables iPad apps to be ported to macOS, there will be more apps for the Mac. Some of the Catalyst apps have some rough edges and not all of the frameworks are available yet, but things look promising: https://9to5mac.com/2019/10/07/macos-catalina-catalyst-apps/. Finally, Apple has been telling developers since Snow Leopard was released in 2009 about transitioning to 64-bit. |
Every platform has to balance the developer experience with the user experience. Microsoft, with their incredible backwards compatibility support, has one approach, whereas Apple has a very different one.
There is no right or wrong way.
