Apple will start selling new Macs next week with its own Arm M1 processor, which boasts very high performance in single-core and multi-core use, but also in graphics processing and other operations. However, support for third-party applications is important because the pre-installed new macOS Big Sur operating system will run in the native version for this chip.
One of the key applications is certainly the office suite Microsoft Office. But it will not have native support in the beginning, so it will only run through the Rosetta 2 system, which is a form of emulation or translation layer.
The principle works relatively simply – only the first time you run the application, the application is translated so that it works quickly on the M1 chip. This process starts only on the first start and takes about 20 seconds. Then the system saves the already translated application and the next run is already running at the normal speed of the already translated version.
However, Microsoft specified that the native version, or the two-way form compatible with M1 and Intel (Universal Binary) chips, is in development, although it has not yet delivered when we will see the final version. Until then, Microsoft recommends installing the latest version of Office from November (build 16.43) and later.
