Free Mac Os For Virtualbox Mac OS X El Capitan 10.11 ISO / DMG Files Direct Download. Mac OS X El Capitan: Being the 12th major release of macOS, Mac OS X El Capitan belongs to the Macintosh-Unix family of OS. It was majorly released for server OS for Macintosh computers and Apple Inc.’s desktop. Running OS X El Capitan 10.11 in VirtualBox. I need to install OS X El Capitan 10.11 as guest OS in VirtualBox running on macOS High Sierra 10.13. I followed the instructions in this guide. I obtained the OS X El Capitan image from here and modified it as outlined in the guide. On startup I get a kernel/cpu panic and was unable to boot.

One well known issue of running a guest MacOS X under VirtualBox is that it'snot possible to enter Recovery OS by pressing the Command+R key combination onVM startup. In fact after reading some bug reports on VirtualBox bugtracker itseems that it's not possible to enter Recovery OS at all.

Fortunately, we don't even need Recovery OS to disable System IntegrityProtection. We can use the Installer environment to run csrutil tool. SIP'sconfiguration is stored inside NVRAM, so it actually doesn't matter whatapproach we will take, as long as we will put some magic values into magicvariables inside NVRAM. Please be advised that while this method works, it willwork until the shutdown of your VM. You can do soft restarts, but if you'll shutdown the VM and boot it up again, you will need to disable SIP again.

In order to access Installation environment under VirtualBox, you will need toenter the VirtualBox EFI BIOS by pressing F12 few times, at very early stage ofguest VM boot up.

You will be greeted with an old school text mode BIOS interface, in which youshould choose the Boot Manager option.

Inside, launch EFI Internal Shell to enter EFI commandline mode.

After getting the command prompt, switch to the FS2: drive:

Of course, your drive number can be different, depending on the partition tablestructure you've chosen to have.

On the FS2: drive, in com.apple.recovery.boot directory, there is a EFIprogram inside the boot.efi file. We need to launch it.

Any errors that start with ERROR!!! can be safely ignored! :)

The Installation Environment should now start booting up, this can take severalminutes to complete.

When it will load, you need to launch the terminal, from which you will be ableto use the csrutil command:

I've uploaded a video that walks through these steps, so if you'll have anyproblems in understanding anything, you can watch it, maybe it'll help.
