They contain recently browsed web pages, ARM code translated from Intel executables, security data, font information, and much more. And they can cause problems.
Rosetta
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.
Some apps nap, others enter the realm of the undead: they’ve gone, but are being kept in suspended animation. And Rosetta can keep them that way for a long time.
Time has changed in M1 Macs, with the Mach clock ticking every 41.67 nanoseconds. This affects all log entries too, and works differently in Rosetta.
Apple warns that “Rosetta translation applies to an entire process, including all code modules that the process loads dynamically” – here are some implications.
Here are several good reasons that Big Sur will need more storage space than previous versions of macOS.
macOS 11 Big Sur comes with the promise of Macs with Apple’s own processors later this year. So what changes?
