Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

The log shows a triple fault exception.

In my experience this usually means a corrupted boot drive.

Where did the ISO come from? I'm not a Mac user, but it's my understanding that MacOS installs don't typically come in ISO form.

Also VHD format seems like a weird (and poor) choice on a MacOS platform.

It should be said that I'm not entirely certain which drive this VM tries to boot from. Being EFI it isn't necessarily the CD/DVD drive.

Thank you for your analysis. It's appreciated. The installer app came from Apple. I converted it from a .app to .cdr to .iso format, thinking that it's what I needed to do for Virtual Box. I shall retry it as a .cdr instead of an .iso bootable installer. I hope I understood your analysis correctly.

As far as I know, .cdr and .iso will be the same thing: images of a CD/DVD. The only "conversion" needed would be a file rename.

I'm less concerned with the extension than I am with how the image file was created. I.e. How did you convert an app into a CD image? Please tell me your method, or give me the link to the guide you followed. Hopefully it was this one: viewtopic.php?f=22&t=81443.

Regarding the choice of VHD... Please don't. At some point you will try to install MacOS again, at that time please use the native VDI format of VirtualBox.

Hello mpac. Thank you very much for your analysis and the hyperlinks. I was able to find the right tool and sift through instructions to create a bootable .iso file of Mojave. It installed into Virtual Box but I discoverred that it's just as lagging as Parallels Desktop for Mac. I was happy that I got it installed but disappointment at performance. I really do appreciate your help though. My next step is to try and figure out how to install a Linux base as an extra partition into my iMac. I'm looking into Ubuntu, Manjaro and QEMU but I'm still a newbee at all this virtual "stuff". I will hand on to Virtual Box though for some testing.

Licensing problems ensure that MacOS is not an officially supported guest OS in VirtualBox, but I'm surprised you can't make it run better in Parallels, being a Mac only solution. Very bad performance may indicate a poor VM configuration.
