Dear Experts,
I am using qemu for fun on Mac OSX 10.15, using QEMU from brew.
qemu-system-i386 / qemu-system-x86_64 / qemu-system-ppc all hang up at the beginning, with black screen.
Just run "qemu-system-i386" itself without any input, it hangs with black screen.
Event with -monitor stdio, it won't take any input.
But Ctrl-C can terminate the program.
Quans-MacBook-Pro $ qemu-system-i386 -monitor stdio
QEMU 4.1.0 monitor - type 'help' for more information
(qemu)
qemu-system-i386 -version
QEMU emulator version 4.1.0

I have also built from the latest git master branch, it is the same:
./qemu-system-i386 -version
QEMU emulator version 4.1.50 (v4.1.0-1571-g69b81893bc)

Everything worked before (last week).
I don't know what I did may cause such a problem.
Any help would be appreciated to debug this.
Thanks,
Quan
