Mavericks host, Mavericks guest, how to?

Postby orpheist » 4. Jun 2014, 03:19

I notice some people mention running Mavericks as guest on Mavericks but I was wondering if anyone could share a how to on creating the initial boot image.

I'm running on a fairly recent MacBook Pro (i7, plenty of RAM).

I know Mavericks doesn't normally come with a bootable disk image, just the Install OSX Mavericks application which I've stashed... I tried using the InstallESD.dmg disk image that it contains, and I do get to a configuration boot-manager screen in VirtualBox but can't seem to actually make it boot or install (I just get to a UEFI Interactive Shell prompt).

FWIW I did try previously installing Snow Leopard Server from a factory disk, thinking to upgrade to Mavericks from there, but I could not get it to work - it would install but then never make it to the first reboot (black screen/hang).

Thanks for knowledge!

Here is a terminal script that solves the problem nicely. You'll need at least 16 GB free in your hard drive in order to do this.
• Start with "Install OS X Mavericks.app" in your "/Applications" folder. If not, correct the script.
• End with a "Mavericks.iso" in your desktop.
• You don't have to be an admin to do this.

Code: Select all   Expand viewCollapse view
# ==============================================================
# 10.9. Make an ISO from the Install.app
# ==============================================================
# Mount the installer image
hdiutil attach /Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

# Convert the boot image to a sparse bundle
hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Mavericks

# Increase the sparse bundle capacity to 8GB to accommodate the packages
hdiutil resize -size 8g /tmp/Mavericks.sparseimage

# Mount the sparse bundle for package addition
hdiutil attach /tmp/Mavericks.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build

# Remove Package link and replace with actual files
rm /Volumes/install_build/System/Installation/Packages
cp -rp /Volumes/install_app/Packages /Volumes/install_build/System/Installation/

# Unmount the installer image
hdiutil detach /Volumes/install_app

# Unmount the sparse bundle
hdiutil detach /Volumes/install_build

# Resize the partition in the sparse bundle to remove any free space
hdiutil resize -size `hdiutil resize -limits /tmp/Mavericks.sparseimage | tail -n 1 | awk '{ print $1 }'`b /tmp/Mavericks.sparseimage

# Convert the sparse bundle to ISO/CD master
hdiutil convert /tmp/Mavericks.sparseimage -format UDTO -o /tmp/Mavericks

# Remove the sparse bundle
rm /tmp/Mavericks.sparseimage

# Rename the ISO and move it to the desktop
mv /tmp/Mavericks.cdr ~/Desktop/Mavericks.iso
