Re: [hatari-devel] macOS : FPU using EmuTOS

That is up to you. However, you can change it once, make your Hatari change, and set it back to how it originally worked. Unfortunately, Apple does not have the default behavior of the function keys as a function key. That causes problems for programs like Hatari.
