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

[Bob Carpenter <hatari@xxxxxxxxxx>]

You can go into Keyboard System Preferences and check "Use F1, F2, etc. keys as standard function keys". That will change F12 to act as a function key which will bring up the SDL menu in Hatari. I have left it permanently set that way because I rarely use the function keys to adjust the sound or brightness. Since I use a MacBook Pro, I use fn-<function key> if I want to use the special functions that macOS builds into the function keys,

Hi,

I have a 5k 27" iMac mid-2019 under macOS Mojave, and there's no
<fn> key on the keyboard. That's why I ask if the SDL UI is mapped ?
F12 is augmenting the sound level, but doesn't call SDL UI ...
