virtualbox.org

Hello, i am trying to install El Capitain on a mac running with OSX 10.8.5. It has 12 gb ram and a 520 Gb SSD.
I installed the lastest VRbox, and set up a VR machine. But when i choose the ISO file and run the machine nothing happens it just says:
Press ESC in 4 sec to skip startup.nsh or any other key to continue. And then it just says 2.0 Shell....

But if i read many tuts on Yosemite in a VRBox it should automatically startup and i can choose to install.

How did you create the .iso and which version of 10.11 did you use? developer preview 1 or public beta 1?

I used this script to create the .ISO
And i have OS X El Capitan Public Beta 7

First let me state I have not tried to install the 10.11 Public beta as a guest. I do have a couple questions though. Did you rename the "Install OS X El Capitan Public Beta.app" to "EL_CAPITAIN.app" and did you read somewhere that was permissible? The other question I have is do you have the full 6+ GB installer or the 2+ GB delta updater?

FWIW I have read in a few places that people have successfully installed the developer beta as a guest but had issues with the public beta.

Lastly, I assume you are aware that there are no guest additions for OSX guests and therefor many features will not work.

yes i renamed it, for the script to work.
And yes i have the "Install OS X El Capitan Public Beta.app". 6 GB.

All I can say is I've never seen people renaming the app to create the .iso. That doesn't mean it won't work. However the error you are getting is the same error others had trying to create a guest using the public beta whereas they didn't get the error with the developer preview. Not just with VirtualBox btw.

Seeing OSX is not a supported guest in VirtualBox, you'll have to wait until someone has successfully installed the public beta in VB and hope they report how they did it on the forum.

Thnx for the info

anytime.

Code: Select all

hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/EL_CAPITAIN

hdiutil detach /Volumes/install_build

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

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

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

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

And i have OS X El Capitan Public Beta 7

for some guide, you need cp BaseSystem.dmg and BaseSystem.checklist to install_build.
but, I met same problem even if i have copied those files.

Just to clarify some things, not all of the developer or public seeds were full installers but updates only so of course you couldn't use the update images to create a guest. That being said, El Capitan has been released so you can create a VB guest on an OSX host if you care to.

Take a look at this thread on the Mac OS X Guests board (actually, this is where this thread belongs as well, but, hey...), especially the explanation that I found in a linked article.

personalty I use VirtualBox for Windows and Linux guests but a nameless hypervisor for OSX guests. One because of the lack of guest additions for OSX in VB and two because I can just drop the OSX install apps onto the program without converting them to an .iso.
