All Macs have been 64-bit for at least 11 years, if not longer. (My MBP from 2012 was 64-bit.)
Apple dropped 32-bit support a long time ago. Not sure of the exact date, but sometime around 2015-2017 I had to port a Mac application to 64-bit because the upcoming release of MacOS was going to drop all 32-bit support.
Yeah… I wasn’t really getting at it not working on 32bit, more getting at it not working on arm.
If it doesn’t acquire the ability to run arm binaries, it will be a retro computing platform in a couple of years. (And it would have to emulate apple’s cpu extensions, even when running on arm chips, yes.)
x64 means x86-64 in common parlance. Apple silicon would be an arm64 platform in comparison. Lots of software is compiled for both right now, but Apple is abandoning x86-64 so at some point in the future, software will stop being built for that platform (just like ppc before x86).
The PowerMac G5 and iMac G5 all the way back to 2003 are 64-bit. Apple actually had to drop 64-bit for one year during the intel transition in 2005-2006. (The original Intel Core Duo chips were 32-bit.
Darling is not for running anythig on a Mac but for running OS X software on other computers. That means not supporting Apple-ARM only becomes a problem once software you want to run is no longer available for x86.
