### Notes
* Enoch bootloader is not used for macOS High Sierra. Clover is used instead.
### Host System Details
Known to work on:
* Fedora 26/27 running on Ryzen 7 1800X CPU.
* Fedora 27 running on i7-6600U CPU.
* Fedora 27 running on i7-5820K CPU.
* Ubuntu 17.04 running on i5-6500 CPU.
* Gentoo (October-2017) running on AMD FX-8320 CPU with AMD RX 470 GPU
passthrough.
Tested with QEMU >= 2.10 (with an out-of-tree patch) and Linux 4.10.x / 4.12.x.
A CPU with SSE4.1 support is required for macOS High Sierra. Intel VT-x / AMD
SVM is required.
### Installation Preparation
#### Preparation steps on your current macOS installation
* Download macOS High Sierra installer from Apple App Store.
If you are getting a partial installer from the Apple App Store, [follow the instructions here](http://osxdaily.com/2017/09/27/download-complete-macos-high-sierra-installer/) to get the full (5GB) version instead.
* Clone this repository. Files included in this repository are needed for ISO
creation.
```
git clone https://github.com/kholia/OSX-KVM.git
```
* Run the ISO creation script `create_iso_highsierra.sh` included in this
folder. Run it with `sudo`.
* Copy the generated ISO image from your Mac's Desktop to your QEMU/KVM machine.
#### Preparation steps on your QEMU system
* Clone this repository again on your QEMU system. Files from this repository are used in the following steps.
* Install required software packages.
```
sudo apt-get install qemu uml-utilities libguestfs-tools
```
* Build and use QEMU from source. See http://wiki.qemu-project.org/Hosts/Linux for help.
```
# First edit /etc/apt/sources.list to add/uncomment deb-src lines
sudo apt-get update
sudo apt-get build-dep qemu
git clone https://github.com/kholia/qemu.git
cd qemu
git checkout macOS
git submodule init
git submodule update --recursive
./configure --prefix=/home/$(whoami)/QEMU --target-list=x86_64-softmmu --audio-drv-list=pa
$ make clean; make -j8; make install
```
This step is not optional and is required. QEMU 2.10.1 shipped with Fedora 27 works fine too.
* See [networking notes](../networking-qemu-kvm-howto.txt) to setup guest networking.
* Create a virtual HDD image where macOS will be installed.
```
qemu-img create -f qcow2 mac_hdd.img 128G
```
* Create bootable Clover disk.
```
sudo ./clover-image.sh --iso Clover-v2.4k-4380-X64.iso --cfg clover/config.plist.stripped.qemu --img Clover.qcow2
```
Instead of building your own bootable Clover disk, you may use the included `Clover.qcow2` disk image.
### Installation
To install macOS High Sierra, use the included `boot-macOS-HS.sh` script.
Note: Ensure that the OVMF resolution is set to 1024x768. This can be done via
the OVMF menu, which you can reach with a press of the ESC button during the
OVMF boot logo. In the OVMF menu settings, set Device Manager -> OVMF Platform
Configuration -> Change Preferred Resolution for Next Boot to 1024x768 . Commit
changes and exit the OVMF menu. Relaunch the `boot-macOS-HS.sh` script.
#### Installer Steps
* After booting, the initial language selection should show up.
* After selecting the language, fire-up the Terminal program and prepare the
hard drive for installation.
```
diskutil list
diskutil eraseDisk JHFS+ macOS disk0 # adapt this according to your system
```
High Sierra's Disk Utility does not recognize unformatted disks, unless you
click View > Show All Devices, quit Disk Utility, then relaunch it.
Thanks to https://tinyapps.org/blog/mac/ and xenadu02 for this tip.
* When done, quit Terminal.
* Now, you can continue with the installation as usual.
* When finished, the VM will reboot automatically and the first time setup continues as usual.
#### Post-Installation Recommendations
* Install Clover to the main hard drive where macOS High Sierra was installed
in previous steps. See [UEFI notes](../UEFI/README.md) for details.
* For debugging and general tips, see the main [README.md](../README.md) file
and [notes.md](../notes.md) file.
* For USB and GPU passthrough notes, see [UEFI notes](../UEFI/README.md) file.
