High Sierra 10.13 #28

Closed fieryo closed 6 years ago

fieryo commented 7 years ago

It seems that macOS 10.13 has changed the installer and BaseSystem.dmg is no longer in the InstallESD.dmg. I tried to make an iso using the BaseSystem.dmg/.chunklist that is inside the installer, but when the installation starts (after the selection of the language) an error appears that OSXInstall.mpkg is broken.

Any idea how to create macOS 10.13 beta iso from the installation app?

fieryo commented 7 years ago

I installed High Sierra as an update to Sierra in VirtualBox 5.1.23, following this blog.

I'm still curious how to create iso for High Sierra, though.

The question is how to create an iso from the High Sierra's SharedSupport files. InstallESD.dmg has different structure than Sierra's one. Nether this nor this scripts work in VirtualBox.

grahamperrin commented 7 years ago

My first edition of prepare-iso.sh for build 17A264c of Mac OS X 10.13 produced an installer that failed with these three lines:

macOS could not be installed on your computer

The path /System/Installation/Packages/OSinstall.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again.

high sierra running - oracle vm virtualbox

From the mention of the second line at https://github.com/munki/createOSXinstallPkg/blob/master/README.md I understood that the problem was not necessarily with OSinstall.mpkg.

Re: https://github.com/geerlingguy/macos-virtualbox-vm/issues/31 I decided to experiment with ditto(1) instead of cp(1). Result:

The end result is better – progress through (and long beyond) the eligibility check, population of the macOS Install Data folder, etc. – but somewhere towards the end of the installation routine, a failure occurs and the guest restarts before I can read the log. I'd like to keep that failure separate from this issue #28.


My current edition of prepare-iso.sh is too rough for a pull request. 10.13-related lines can be inferred from the Terminal output obve.

grahamperrin commented 7 years ago

@geerlingguy work in progress https://gist.github.com/grahamperrin/d6b9e979d46708b41cdd25d79552a4cb includes some cosmetic changes. Not tested.

In particular, please note that for compatibility with 17A264c some lines were simply, lazily, commented out; so we should not expect this lazy edition to work with the installer for Sierra or earlier.

styxlab commented 7 years ago

I managed to get 10.13 Beta running. Thanks to this thread! Has anyone had success with connecting a real device (iphone, ipad) to the virtual machine. It is not working anymore since macOS Sierra 10.12.4: Although the device manager does detect the iphone, neither itunes nor xcode detects the device.

Update: I can confirm the issue is only present with virtualbox. It works fine with vmware.

lony commented 7 years ago

@grahamperrin I made a PR https://github.com/geerlingguy/macos-virtualbox-vm/pull/37 using your gist. I could now create the ISO and also install 10.13. Sadly after rebooting I get the following error:

archesaurus commented 7 years ago

I am experiencing the exact same issue @lony

Installer ISO boots and appears to finish but install is actually botched and unbootable.

daneov commented 7 years ago

Tried to accomplish this using the Resources/createinstallmedia executable to create the bootable image, same result :/

@archesaurus steps worked great for me, thanks!

geerlingguy commented 6 years ago

@tobiwashere @archesaurus - If someone wants to modify the directions in this repo in a PR (or base off https://github.com/geerlingguy/macos-virtualbox-vm/pull/37 and touch it up), I'll be happy to merge (and close out this issue :) ).

Thanks for adding your notes! I've just gone to High Sierra on one of my Macs, and will soon be needing to run it in a VM too... so thanks for doing the hard work of getting it all working together and documenting it!

dotCipher commented 6 years ago

@geerlingguy I took a stab at adding some docs for the steps needed involving the EFI problem in #39 . Let me know if the wording makes sense. I also conformed the original PR (#37) to your format of spaces (since the original had tabs).

dotCipher commented 6 years ago

Strangely enough, when testing I found that I am unable to get High Sierra to boot correctly. When booting I get: Error loading kernel cache (0x1) however when I boot to the EFI terminal I am unable to load into FS1:

eelkeblok commented 6 years ago

Might it be case-sensitive? I ran into the same issue, but following the instructions in the readme got me through this. The first step states 'fs1:', though, not 'FS1:'.

philipnewcomer commented 6 years ago

I ran into the same issue where after the initial installation, FS1 was not recognized in the VirtualBox UEFI shell. Turns out I had checked the SSD option in VirtualBox for my virtual hard drive, and the drive was formatted as APFS, which the VirtualBox EFI BIOS does not yet support. Since the VirtualBox BIOS could not read the APFS-formatted drive, it could not be selected in the EFI boot manager. When I unchecked the SSD option and reinstalled macOS (which formatted the drive in HFS+), I could then boot from FS1 in the UEFI shell.

dotCipher commented 6 years ago

fs1: didn't work for me either, same issue. @philipnewcomer can you elaborate on the steps you took to get it to work? I am still not sure how to correctly repro how you applied your fix.

eelkeblok commented 6 years ago

I suppose the trick is to make sure the virtual disk is formatted with HFS+. I'm assuming that having the SSD option for the virtual disk unchecked is a prerequisite to be able to do so (since High Sierra apparently will always format SSDs as APFS).

philipnewcomer commented 6 years ago

@dotCipher first you have to turn off the Solid-state Drive option in the VM's storage settings: screen shot 2017-10-23 at 7 24 54 pm

Then you need to boot from the macOS installer disk image, erase the drive, and reinstall macOS.

If the installer detects a solid state drive, it will automatically (re)format the drive in APFS during installation, which is why you have to erase and reinstall after changing the drive type in VirtualBox before you can boot.

dotCipher commented 6 years ago

@philipnewcomer Yeah I had SSD turned off originally. I ended up updating my version of VirtualBox and running the script commands one-by-one in order to get it to work. It seems like the script doesn't Unmount the sparse bundle correctly (notice the first error in the output below: hdiutil: couldn't unmount "disk3" - Resource busy)

Plus it seems like I get an xargs: illegal option -- - before the createISO function is called (during the Eject installer disk in case it was opened after download from App Store step (see hdiutil info | grep /dev/disk | grep partition | cut -f 1 | xargs --no-run-if-empty hdiutil detach -force ).

Seems like the change present in PR https://github.com/geerlingguy/macos-virtualbox-vm/pull/36 fixes it.

See #39; I plan on merging that to get High Sierra support added (finally). Sorry about the delays... health problems kind of knocked me out for the past year or so :(

geerlingguy commented 6 years ago

So... I'm getting the following message repeated ad infinitum when I first boot the VM with the High Sierra ISO mounted:

Attempting system restart...MACH Reboot
geerlingguy commented 6 years ago

As it turns out, it's important to choose "Mac OS X (64-bit)" Instead of the High Sierra option for the VM; if you choose High Sierra as the version VirtualBox seems to not allow reboots to work right for some reason?

To illustrate, choose the following:

geerlingguy commented 6 years ago

So after going through installation (the installer seemed to also download the macOS combo update as well!), I get the error "An error occurred while preparing the installation. Try running this application again.", and if I look at the logs, it looks like the installer is trying to convert the HFS+-formatted drive to APFS:

screen shot 2018-08-15 at 2 16 03 pm screen shot 2018-08-15 at 2 15 51 pm
geerlingguy commented 6 years ago

So I formatted the disk as APFS, and now it gets to the end of the installation process, then I see a bunch of notices/warnings in the installer log, and it reboots... right back to the installer. If I unmount the ISO and reboot it brings up the UEFI boot menu and shell, and won't boot if I try selecting Mac OS X or the Hard Disk as the boot option. Hrm...

Might try using the non-interactive installer and HFS+, maybe VirtualBox disks don't support APFS well?

geerlingguy commented 6 years ago

So I've merged support based on the three older PRs; any new issues should be added as new issues in the issue queue. Currently, my testing shows that formatting as APFS seems to get the initial installation working correctly, but on reboot it just goes back to the installer again. Debugging that now.
