VMware Fusion: Catalina Guest on Mojave Host

Hi there! I've seen other threads on Catalina and VMware Fusion, but they all seem to be about running Fusion under a Catalina host. I'm trying to get Catalina installed as a guest under a Mojave host. The problem is (as others have indicated), it gets stuck at the Apple logo. If I start it with Cmd-V for verbose mode, I see a kernel panic:


Unable to find driver for this platform: \"ACPI\".\n"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6110.0.0.121.5/iokit/kernel/IOPlatformExpert.cpp:1994


My first instinct is that it's because my primary workstation is a ... let's just say it's custom-built about 2 years ago so I could run lots of VMs on heavier hardware than Apple had available at the time. However, seeing as others are having this problem (and presuming at least some of them are running on "standard" hardware) I don't believe this is that.


For context, I initially tried upgrading a duplicated Mojave guest machine (used for a clean testing environment) with Catalina beta 1. Most recently, I tried this approach with a freshly-duplicated Mojave guest with Catalina beta 2, then just a new VM using the Catalina beta 2 installer directly (which, surprisingly, didn't earn me a warning from VMware about an unsupported version). All resulted in the same kernel panic at startup.


I'd appreciate any insights. I hope the title of this thread is clear enough that it redirects others who've made the same mistake I have in following the wrong threads (those about Fusion on a Catalina host).


I hope also that the moderators will be willing to overlook my allusions to "non-standard hardware", given the unique challenges of developing for Apple's ever-changing platforms while being forced to support and test under outdated OS versions with pro hardware that hadn't been upgraded in far too many years. 😍

I was facing a similar challenge and this thread helped me: https://communities.vmware.com/thread/611961

Have you tried installing Mojave as a guest then upgrading to Catalina beta from there? Just a thought.

Yes tried it and it did not work for me .

Yes, as I'd stated in the 4th paragraph of my post. 😉

Thanks, EricRFMA! The thread links to a blog post that says, basically, start installing it as a new OS let it get stuck at boot, shut it down, switch the Settings->General->OS to Windows 10 x64, then boot. It works perfectly.

After the system is set up you can switch the Guest back to run as OSX 10.14.
