They’re everywhere: whatever you do, something somewhere will cache it. Later that can cause puzzling problems, but makes our Macs faster as a result.
Rosetta
Rosetta 2 is key feature for the transition to Apple silicon, and is also available to run Intel x86_64 binaries in virtual macOS and Linux (in Ventura).
Now feature-complete with support for shared folders with the host Mac, and everything is in place for Rosetta 2 translation of x86_64 binaries within the VM.
Why would Apple invest several years of hardware and software engineering just to see what 3rd party developers might do with it?
Ventura can use Rosetta 2 to translate Intel binaries inside an ARM-native virtualised Linux. The impact and importance of this is explained.
For the great majority of Mac users, M1 series Macs are a big step forward. But some users want the impossible. What can’t M1 Macs do?
They contain recently browsed web pages, ARM code translated from Intel executables, security data, font information, and much more. And they can cause problems.
Two basic rules: M1 Macs run Arm-native code when it’s available, but won’t mix ARM-native and Intel code in the same process. Here are the details.
Internally, it isn’t called Rosetta, but OAH. Although itself tiny, its demands on memory and CPU can be great. Details of how and what it does, and more.
A short introduction to some of the highlights and quirks of M1 Macs, from dealing with apps which don’t run properly, to entering Recovery Mode and dealing with disaster.
