You can't read them if you don't speak Chinese. In the same way, a translated app will never be as good as a native app.īut given that super-complete Chinese dictionary, you look up English words and phrases and it gives you some characters to write down. If I give you a copy of a very long book, such as The Lord of the Rings, and a very big very complete English-to-Chinese dictionary, you could given enough time produce something that was kind of like the LotR in something like Chinese, but it will never be as good as a translation by a Chinese native who speaks English.

It interacts with the host CPU and the guest OSes and the programs on them run on that host CPU too.

An x86 hypervisor can virtualise multiple x86.īut you can't just run a hypervisor through a translation tool such as Rosetta. A hypervisor splits up a CPU into multiple instances, each of which can run a separate OS.Īn ARM hypervisor can virtualise multiple ARMs. In each case it's provided some kind of emulation for the generation immediately before which can run some, individual programs from the old architecture.Ī hypervisor is not just 'a program'. They're also under the impression that Rosetta 2 will magically allow Windows 10 in a VM, like on current Macs.Īpple has used 4 CPU architectures so far: (The RAM is DDR4 in a separate die - just a single die, which is possibly a bad sign bandwidth-wise - that is in in the same physical package as the SoC, like a Pentium II's L2 cache was.) These guys - and they are almost all guys - would rather run an unstable beta of a newer OS than the stable, patched version of 10.5 with its plethora of stable, supported PowerPC apps.Ĭurrently, they're getting very excited about the new ARM Macs and excitedly telling one another about how fast they are and how Rosetta 2 can magically translate any x86-64 app into a full native ARM app and how the M1 is a system-on-a-chip and therefore the RAM is built in to the processor and so is much faster than boring external RAM. This was apparently a late decision and 10.6.0 did have an unfinished version that ran on the older PowerPC chip. 10.6 'Snow Leopard' was the first Intel-x86-only release of OS X. As an example they got very excited recently because someone found a leaked beta of Mac OS X 10.6 for PowerPC. The excellent LowEndMac website for users of vintage Apple kit has a thriving FB community, which is full of the sort of people who recommend that whatever your vintage Mac, you crack its firmware and run the latest OS on it.
