This makes literally no sense at all. Why on Earth would Apple disable user installed 32bit programs that aren't using system libraries?
This sounds like something that's speculative or not interpreting the evidence properly. Removing the 32bit libraries has potential upsides in terms of having less installed on the computer and less loaded into memory, but going further than that to outright preventing them from running at all makes no sense at all.
01kipper: According the article I linked, at least with WINE, even a 64-bit emulator will still only be able to run 64-bit games, 32-bit games on a 64-bit emulator will still not work. I don't know whether similar reasoning will apply to emulated DOS games (which I believe are 16-bit?) if a 64-bit Boxer emulator appears.
SirPrimalform: There's no such thing as 64-bit DOS games. Hell, I'm pretty sure that there's no such thing as a 32-bit DOS game. Doesn't matter either way since DOSBox is an emulator and emulates a 16-bit environment. A 64-bit build of DOSBox should run 16-bit DOS games just fine.
In the case of DOSBox, the actual executable as far as the OS is concerned would be 64-bit even if the software running inside of it was actually 8 or 16-bit.
This whole thing only makes sense if Apple is planning to switch to a 64bit only architecture, but those failed pretty hard last time around and I doubt that Intel is going to try it again.
Ganni1987: This is very bad for Mac gamers as the majority of games are still 32bit. All those games created in the 2000's wouldn't be able to run, hard to imagine it.
TBH, a huge chunk of those games will run under virtualization, but it does seem like a truly bizarre decision to make and I assume that there was a misunderstanding here.
