Kinda fascinating that a Visicalc file could be transfered from a 5.25 floppy from late '70s early 80s all the way to the latest MAC,
The file may be able to be transfered but program binaries intended for non-x86 MACs aren't going to run on the latest MACs without a third party emulator.
while Windows running on X64 can't even handle a 16-bit installer without external support...
Apple drops support for legacy applications far quicker than MS does.
Mac OS X was launched as a consumer product in 2001. Intel Macs were released in 2006 with no support for classic mac OS apps, classic support was removed from the powerpc releases of Mac OS soon afterwards.
Support for rosetta was removed in 2011.
On the MS side win32 was brought to most customers with windows 95 in 1995. The first 64-bit desktop version of windows didn't appear until 2005 and didn't become common for several years after that.
