If eons in this universe equalled nanoseconds in a higher-level universe on a single particle that's currently emulating this entire universe? How meta! Imagine, just ponder briefly, if this whole universe was theoretically just a virtual world, at danger of being terminated at any nanosecond.

The virtual Mac instantly disappears into nothingness as I browse away from the web page, only to come back as a brand new, fresh Mac completely virtually recreated from scratch, when I revisit the page. Never, to even become nearly as sentinent as holodeck character James Morarity in Star Trek. Only to blithely disappear just like a quantum virtual particle when the user browses away from the webpage. Existing only in an etheral virtual "universe" that the web browser represents. Little does the Mac itself knows it took the metaphorical equivalent red pill instead of the blue pill. It's neat, these ethereal one-click emulators in web browsers. (I think the same is true on MacOS, but I haven't checked for sure recently.)Īnd as an added bonus, using Javascript to emulate a whole OS means that the virtual Mac will probably perform about like the real thing did 30 years ago.Ĭurrently, it seems to be performing pretty close to an approximately 1990s era mac, when using a single thread of my i7. They're tagged pointers, and the refcount is stored inside of the atomic value.
One reason memory management under ARM64 is so much nicer than under ARM32 is.

I ran some really really old software that way.Īlso also incidentally: the whole "not 32-bit clean" thing is sorta happening again on iOS. Apps under "Classic" did not need to be "32-bit clean" (remember that?).
OS X Server is licensed for use in VMs (the non-server versions were not until 10.7), and it includes Rosetta.Īlso incidentally: some apps ran better under "Classic" than running under OS 9 directly. Incidentally, Rosetta is the reason I keep a copy of OS X Server 10.6 running in a VM. You could run classic on a PPC Mac up through 10.4.x (not on PPC Leopard or Intel Tiger). So basically an emulator nested in an emulator. Up until OS X 10.7, if you had an Intel Mac, you could still run a 1984 Mac application via Rosetta emulating the PPC CPU and running "classic" OS 9, which in turn ran the Mac 68k emulator to run the old code. It's somewhat crazy to think that the Mac has gone through 2 complete CPU architecture changes.
