The issue was corrected with Hatari v.2.3.1 booting EmuTOS 1.0.0 ...

Thanks for the patch that was proposed by Jérôme Vernet for macOS.

But I noticed another issue with EmuTOS 1.0.1. The Falcon030 is
booting very slowly, and the hostfs (the Macintosh drive C:) is
no longer recognized with Hatari v.2.3.1. Only A: and B: floppies
are mounted. So Hatari doesn't boot regularly with EmuTOS 1.0.1.
Only EmuTOS 1.0.0 recognize the hostfs, and boots correctly ...

Thanks by advance for any help =)

Best regards,
