I found the possibility to install VMs via VirtualBox. This raised a question in my mind:
Is it possible to run macOS in a VirtualBox machine using it remotely inside the home network?
If yes: Is there any VM specific Hardware I need (USB Card Special Motherboard)? Or can I just upgrade to 16 or 32 GB of RAM and a i5 or i7 instead of my Current Hardware?
I Managed, test wise, to install a Windows 10, but it runs very poorly with strange Video output.
Thanks in advance for your Ideas!
