# Install QEMU OSX port with ARM support

```
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 
&& brew update 
&& brew install qemu 
export QEMU=$(which qemu-system-arm) 
brew install wget
```

#### *get stretch kernel, device tree and raspbian image*
```
wget https://github.com/dhruvvyas90/qemu-rpi-kernel/raw/master/kernel-qemu-4.9.59-stretch
export RPI_KERNEL=./kernel-qemu-4.9.59-stretch
wget https://github.com/dhruvvyas90/qemu-rpi-kernel/raw/master/versatile-pb.dtb
wget http://downloads.raspberrypi.org/raspbian/images/raspbian-2018-11-15/2018-11-13-raspbian-stretch.zip
unzip 2018-11-13-raspbian-stretch.zip
export RPI_FS=./2018-11-13-raspbian-stretch.img
```
#### *Here make sure to reference the .img file in the last EXPORT and not the .zip file as per original instructions.*

#### *Tweak filesystem: start qemu with init flag, switch to guest window to execute tweak and close window afterwards*
```
$QEMU \
-kernel $RPI_KERNEL \
-cpu arm1176 -m 256 \
-dtb versatile-pb.dtb \
-M versatilepb \
-no-reboot -serial stdio \
-append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash" \
-drive "file=2018-11-13-raspbian-stretch.img,index=0,media=disk,format=raw"
```
#### *So at this point you should get the emulator window and a terminal you can add the following commands in.*
```
sed -i -e 's/^/#/' /etc/ld.so.preload
sed -i -e 's/^/#/' /etc/ld.so.conf
sed -i -e 's/^/#/' /etc/fstab
```
#### *Exit that and the next command will start the actual raspberry pi emulation.*

# *Emulate Raspberry Pi*
