Must correct myself a bit …
MacOS 27 drops support for Intel, i.e. the OS cannot be run on Intel CPUs. It also removes the Rosetta component that provides Intel emulation on top of Apple Silicon during the installation of the new OS.
BUT there is a one-year grace period, where you can manually install Rosetta. To my understanding it no longer automatically installs as it did before when needed. You have to do the installation yourself from the command line. But it does work!
So now I have the Suunto Plus environment running on two machines, double the productivity
And Suunto has one more year to upgrade the simulator!
