Running Mojave under Catalina

[lennyeiger]

As many of you know, Catalina only allows 64 bit apps. I have a couple of apps that won't make the cut, at least not right away.

I have Fusion Pro 11.1.1, will likely update to 11.5, and I'm wondering if I can run Catalina army main OS and run Mojave in Fusion. I've used Fusion for many years to run a Windows 10 partition, but that's all, so I'm new to this.

This is probably too obvious, but would love a little help. TIA

I haven't set up that combination yet but I expect it will work fine. I am running Fusion 11.5 on Mojave, with VMs for every macOS version from 10.14 (Mojave) back to 10.7 (Lion), as well as server editions of 10.6 (Snow Leopard) and 10.5 (Leopard). Only some of them get regular use, the others are there for reference on occasions when I want to look at a particular OS to refresh my memory, or test something on it.

One limitation to be aware of for running macOS in a VM: there is no 3D graphics support for macOS guests. (This is not a VMware-specific issue, it also affects the competitors.) This means some applications won't work in a macOS VM, includes anything which requires Metal and probably anything which requires OpenGL. Mojave in theory only runs on Macs which support Metal, but the OS still works without Metal in a VM.

I was also surprised to find the old iWork '09 versions of Pages (4.x), Numbers (2.x) and Keynote (5.x) didn't work in a VM because they use Quartz Extreme to render even simple documents, and Quartz Extreme requires 3D graphics support, therefore you get an empty white window body where the document should be.

I'm dealing with those categories of old/32-bit software by moving them to a second real Mac which will remain on an older version of macOS. I'll be using VMs on my main Mac to run applications which don't have 3D or other hardware dependencies.

I am trying to make a Mojave VM, but am doing something wrong. Any help would be greatly appreciated.

I downloaded the Mojave app from the App Store and used that to create a VM, which it apparently did.

When I go to run the VM I get three errors.

Transport (VMDB) error-14:Pipe connection has been broken

Could not open/dev/vmmom:Broken pipe

Failed to initialize monitor device

Thanks for any suggestion

Hi,

Sounds like you cannot run ANY VM as Fusion cannot even start the vmmon device.

Try rebooting the host.

If that doesn't help then the first thing to try is a re-install of VMware Fusion.

If you still get the same problem it might be due to something else (another application installed that depletes the major character devices)
