This was tested with macOS 10.12.5 and Clover r4114. Without this patch, the macOS boot process gets stuck at the Apple logo without showing any progress bar.
I have documented the process of running macOS on QEMU/KVM at, https://github.com/kholia/OSX-KVM/ Instead of using this patch, adding an additional command-line knob which exposes this setting (force_rev1_fadt) to the user might be a more general solution. --- hw/i386/acpi-build.c | 1 + 1 file changed, 1 insertion(+) diff --git a/hw/i386/acpi-build.c b/hw/i386/acpi-build.c index b9c245c..0f8df19 100644 --- a/hw/i386/acpi-build.c +++ b/hw/i386/acpi-build.c @@ -145,6 +145,7 @@ static void acpi_get_pm_info(AcpiPmInfo *pm) object_property_get_uint(obj, ACPI_PCIHP_IO_LEN_PROP, NULL); } if (lpc) { + pm->force_rev1_fadt = true; obj = lpc; pm->cpu_hp_io_base = ICH9_CPU_HOTPLUG_IO_BASE; } -- 2.9.4
