Do you see the "Your device or computer could not be verified" message when you try to login to the App Store? If yes, here are the steps to fix it.
-
Make sure that your wired ethernet connection is called "en0" (and not "en1" or something else). Use "ifconfig" command to verify this.
-
If the wired ethernet connection is not called "en0", then then go to Network in System Preferences and delete all the devices, and apply the changes. Next, delete /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist file. Finally reboot, and then use the App Store without problems.
This fix was found by Glnk2012 of https://www.tonymacx86.com/ site.
Also tweaking the smbios.plist
file using Chameleon Wizard
can help with
App Store problems.
-
Download Enoch bootloader from http://www.insanelymac.com/forum/ (requires registration).
-
Using Pacifist open the “Enoch-rev.####.pkg” file and extract the file called "boot" from Core.pkg/usr/standalone/i386/boot
-
Rename boot to enoch_rev####_boot.
This option is not recommended. Building latest QEMU from Git repository is recommended instead.
-
Do the following steps as
root
user on the Virtual Machine (VM).cp -a FakeSMC.kext /System/Library/Extensions/ cd /System/Library/Extensions/ chmod -R 755 FakeSMC.kext chown -R root:wheel FakeSMC.kext rm -R /System/Library/Caches/com.apple.kext.caches touch /System/Library/Extensions && kextcache -u / # optional step
-
Remove the
-device isa-applesmc,osk=... \
line completely fromboot*.sh
file(s). -
If you are using the
virsh
boot method, then remove the following lines from yourvirsh
XML file,<qemu:arg value='-device'/> <qemu:arg value='isa-applesmc,osk=XXX'/>
-
Reboot the VM for changes to take effect. Use
kextstat
to verify thatFakeSMC.kext
is loaded. -
Latest
FakeSMC.kext
version can be downloaded from this location. -
If your updated VM is failing to boot and it doesn't have
FakeSMC.kext
installed, the following steps can used to injectFakeSMC.kext
into the VM disk image,$ sudo modprobe nbd # all steps to be executed on the QEMU/KVM host $ sudo qemu-nbd -c /dev/nbd0 -n mac_hdd.img $ sudo fdisk -l /dev/nbd0 ...

-
Build xar from http://mackyle.github.io/xar/ on a Linux box.
-
Extract "boot" from using the following steps,
xar -x -f Enoch-rev.2848.pkg gunzip -c Core.pkg/Payload | cpio -i cp usr/standalone/i386/boot enoch_rev2848_boot
If you want a larger VNC screen add the following to the bootloader config in /Extra/org.chameleon.Boot.plist:
<key>Graphics Mode</key>
<string>1440x900x32</string>
Make sure to pick a resolution that is supported by the SeaBIOS used by QEMU. The full list can be found in the source for SeaBIOS located here.
For example, setting the resolution to 2560x1440x32 will not work. OS X will boot with the next lowest supported resolution which is 1920x1200x32. Instead, use 2560x1600x32 and it will work.
If you want larger VNC/SPICE screen edit the Clover bootloader config in
/EFI/CLOVER/config.plist
. In the XML root <dict>
section there is a
<key>GUI</key>
with values in a <dict>
section. Set your resolution
in the following key-value block; create it if it does not exist:
<key>ScreenResolution</key>
<string>1360x768</string>
A simple way to configure this setting, even when you use a separated disk for Clover is by using the Clover Configurator tool, allowing to mount the disk image and setting this resolution from a simple interface.
The resolution set there must be supported by the resolution list in UEFI configuration. EDK II OVMF UEFI resolution must be updated to match the resolution set in Clover configuration. Check the README.md for High Sierra for detailed instructions.
EDK II supports more resolutions than SeaBIOS, however QEMU is currently limited to widths and heights that are multiple of 8. This means resolutions like 1366x768 won't be displayed properly because dividing 1366/8 does not return an integer value. For this particular case, select the nearer 1360x768 resolution instead. VNC implementation may require a multiple of 16, so beware of setting 1080 vertical resolution or use SPICE instead.
Install VMsvga2 from this location. No support is provided for this unmaintained project!
-
Add
-vga vmware
to QEMU parameters in boot-macOS.sh. -
Add the following to
/Extra/org.chameleon.Boot.plist
file.<key>Kernel Flags</key> <string>vmw_options_fb=0x06</string>
Thanks to Zhang Tong and Kfir Ozer for finding this.
See UEFI/README.md
for GPU passthrough notes.
Note: There is no working QXL driver for macOS so far.
No support is provided for this. You are on your own. The sound output is known to be choppy and distorted.
-
Add
-device ich9-intel-hda -device hda-duplex
to the VM configuration.boot-macOS.sh
already has this change. -
To get sound on your virtual Mac, install the VoodooHDA driver from here.
Note: It seems that playback of Flash videos requires an audio device to be present.
See http://wiki.qemu-project.org/Hosts/Linux for help.

Other host CPU features can be similarly exposed to the macOS guest.
The following command can be used on macOS to verify that AES-NI instructions are exposed,
sysctl -a | grep machdep.features
On machines with OpenSSL installed, the following two commands can be used to check AES-NI performance,
openssl speed aes-128-cbc
openssl speed -evp aes-128-cbc # uses AES-NI
Exposing AVX and AVX2 instructions to macOS requires support for these instructions on the host CPU.
The boot-clover.sh
script already exposes AVX and AVX2 instructions to the
macOS guest by default. Modify or comment out the MY_OPTIONS
line in
boot-clover.sh
file in case you are having problems.
To enable AVX2, do the following change,
Clover boot menu -> Options -> Binaries patching -> Fake CPUID -> 0x0306C0 # for Haswell
For details, see this wiki page.
Once enabled, the following commands can be used to confirm the presence of AVX and AVX2 instructions on the macOS guest.
$ sysctl -a | grep avx
hw.optional.avx2_0: 1
hw.optional.avx1_0: 1
$ sysctl -a | grep leaf7
machdep.cpu.leaf7_features: SMEP BMI1 AVX2 BMI2
machdep.cpu.leaf7_feature_bits: 424
Docker for Mac requires enabling nested virtualization on your host machine,
modprobe -r kvm_intel
modprobe kvm_intel nested=1
Also you have to add vmx,rdtscp
arguments to the -cpu
option in
boot-macOS.sh
file.
Configuration options for macOS Sierra (thanks to virtio-net-osx project users),
-netdev user,id=hub0port0 \
-device virtio-net,netdev=hub0port0,id=eth0 \
-set device.eth0.vectors=0
Adapt these to your use case. These changes need to be made in the boot-*
scripts. On the guest, install the included Virtio-Net-Driver-0.9.4.pkg
package.
Update: This is no longer recommended. Use vmxnet3
adapter instead.
Type the following after boot,
"KernelBooter_kexts"="Yes" "CsrActiveConfig"="103"
-
Install Pacifist on OS X.
-
Mount "InstallESD.dmg" file.
-
With Pacifist browse to the above volume (use the "Open Apple Installers" menu option) and then open "Essentials.pkg". Extract the folder & file (Kernels/kernel) located at /System/Library/Kernels/kernel location.
-
After extracting the Kernels folder, place it in the same directory as the ISO creation script.
-
Put "org.chameleon.Boot.plist" in /Extra folder.

If you are unable to wake Mojave from sleep using mouse or keyboard, you can manually wake the VM up from sleep from the QEMU prompt by using the
system_wakeup
command,(qemu) system_wakeup (qemu)
However, macOS crashes on wakeup.
