Error Running Mac OS

[steveg]

I am using VirtualBox 6.0.14 and created macOS High Sierra and Mojave virtual machines from VMDK files. I modified some settings and entered codes using VBoxManage for both. When I start the machines, I see a black screen and the last line shown is "Start CalculateAdler32" in both cases. What do I need to do to fix this?

Buy an Apple Computer.
MacOS is only supported on Apple hardware, so your Hackintosh like thing is not supported here and you won't get help.

That's right. OSX guests are only supported on Apple hardware (which you do not seem to have). I recently made the "OSX guests on non-Apple hardware" a Global post, which means it shows as first on every forum area, makes me wonder how come you missed it...

Also, consider changing your favorite internet search engine. There should be plenty of results about this issue on these forums (all of them locked, hoping that someone will get the hint), but the search engine you're using now, does not seem to return any results for some reason.

Moving to "OSX Guests" from "Windows Hosts".
