Fusion 10 running on 10.13: Can’t create 10.13 High Sierra guest from installer

[BobFillmore]

Trying to create a High Sierra VM on a new MacBook Pro.  I drag/drop the “Install macOS High Sierra” app onto the “install from disc or image” method.  When I click on “Finish”, I get the message: “Unable to create the installation medium”.  Also, when I try to create a VM from the recovery partition, it says it can’t find the recovery partition, even though I can boot the recovery partition with Command-R.

Any solutions?

Hi BobFillmore,

Restarting host may solve the first issue.  For recovery partition on Mac High Sierra, it's a known issue and no workaround now.  see more known issues, please see VMware Fusion 10.0 Release Notes

Hi, Bob

Is your Mac lacking of storage space please?

It needs about 15GB disk space for the whole installation.

And if you like, would you upload the fusion log please?

It locates at

~/Library/Logs/VMware Fusion/*.log

First rule of computing... reboot.  Thought I did that...

Anyway, that fixed it.. thanks!

I believe this error comes about when the High Sierra installation image is mounted on the fusion host.

The process of creating the virtual machine is in many cases:

1. Download latest "Install macOS High Sierra" App from the app store.

2. Close the installer when is starts.

3. Open Fusion and drag installer to the create VM window.

4. Put up with annoying message about being unable to create ...

Workaround:-

1. Open the disk utility app and

2. Unmount the High Sierra installation image that is mounted (but hidden from the desktop).

3. Try and create the VM image now.....

4. No error.
