![]() ![]() If the recovery partition isn't present and valid, these instructions won't work.Ĭlick the second entry. If the second partition isn't the recovery partition, look under the paths in the list to see if one of them is it. The second PCI path is probably to the recovery partition, the one you need to boot from. The first PCI path in the list is probably the boot partition that doesn't contain bootable firmware. You should see two entries in a list (they are cryptic-looking PCI bus paths). Select Boot Maintenance Manager and click. You'll be brought into an EFI text-mode GUI. I was able to fix the UEFI problems as follows (credit to the VirtualBox forum): After manually directing EFI to boot into macOS for the first time, macOS automatically fixed up the boot partition, and subsequent boots worked properly. In my case, after installing macOS into a virtual machine according to these instructions (running the macOS installer from an ISO image downloaded from Apple), on first boot, the boot partition was present, but unconfigured (probably no boot image installed). By now you may have surmised boot.efi is an EFI standard filename that lives at an EFI standard path in a disk partition, and it contains OS-specific boot firmware (e.g., Windows, Linux, etc. Ultimately, the objective is provide a boot partition that contains a macOS boot.efi. Your immediate objective is to help EFI locate and execute OS-specific boot firmware. However, assuming you have a macOS recovery partition on that disk, it should contain a copy of boot.efi (macOS-specific boot firmware) that you can boot into the OS with. If there are any issues with this web page, please let me know.UEFI requires intervention, because the EFI firmware on the Mac's motherboard can’t find valid OS-specific EFI boot firmware in the standard location on disk. extra-ldflags="-L/usr/local/opt/llvm/lib -L/usr/local/opt/libffi/lib -L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib" \ extra-cxxflags="-I/usr/local/opt/llvm/include" \ configure -cc=clang-7 -cxx=clang++-7 -host-cc=clang-7 \ ![]() Note that building for machines with CPUs supporting such extensions will exclude running your binary on earlier machines.Įxport PATH="/usr/local/opt/llvm/bin:$PATH" AVX/AVX2 support), you can install llvm through e.g., brew. If you need to compile with newer versions of clang (to get f.i. To specify a certain version, use the -cc and -cxx options. You can have several versions of GCC on your system. You can build it from source (expect that to take several hours) or obtain third party binaries of gcc available from Homebrew or MacPorts. You may have to install your own version of gcc. Note: If after the configure step you see a message like this:ĮRROR: Your compiler does not support the _thread specifier for The configure script will automatically pick this. We recommend building QEMU with the default compiler provided by Apple, for your version of Mac OS X (which will be 'clang'). You can use './configure -help' to see a full list of options. configure -target-list=i386-softmmu,ppc-softmmu & make say "I'm all done compiling QEMU" If your system has the 'say' command, you can use it to tell you when QEMU is done This way doesn't require you to wait for the configure command to complete: If you don't specify it, all machines would be built. The target-list option is used to build only the machine or machines you want. Make (when installed through brew, make is installed as gmake, so use gmake)Īfter downloading the QEMU source code, double-click it to expand it. GCC might also work, but we recommend clang The clang compiler shipped with the version of Xcode for that OS X.One of the two most recent versions of macOS (currently Catalina or Big Sur).If your host's (your computer) architecture matches the guest's (QEMU) architecture and is running Mac OS 10.10 or higher, then you could speed up execution to near native speed using this option: -accel hvf Should you want to run Qemu with KVM support on a G5, depending on your distribution, you might have to compile your own kernel with KVM support. ![]() KVM is mainly used for x86 (32 and 64 bit) emulation on x86 hosts running Linux. Some system emulations on Linux use KVM, a special emulation mode which claims to reach nearly native speed. 1.1 Installing QEMU using a package manager. ![]()
