Has anyone had the issue, when they own mac hardware, that when they install sound drivers it causes kernel instability, until you upgrade the kernel beyond the LTS recommended, then when installing VBox, due to OS instability with the headers, you need to downgrade the kernel to LTS, causing sound driver instability?
Headers don’t interact with the kernel, so there’s no stability issue there. I assume what you did was install a mainline kernel in an Ubuntu flavor of something, then needed the headers for the Vbox extensions, but headers aren’t available in packages for mainline kernel versions.
You can build VirtualBox and it’s components, or just the components from source. That means install the packages bits, then download kernel source, and use it to build the extensions, then you can package and install them.

I’ll have to look into this! thank you, I was getting around it by using my 2012 Macbook :D
