# The default EFI image included in QEMU 8.1.3 (edk2-stable202302) does not work on Apple M3:
# https://gitlab.com/qemu-project/qemu/-/issues/1990

# The issue is reported to be fixed in:
# https://github.com/tianocore/edk2/commit/5ce29ae84db340244c3c3299f84713a88dec5171
# (included in edk2-stable202305 and later)
#
# Replace the EFI image until QEMU updates it, to rescue M3 users.
