Is it true that Apple's macOS is built on the Linux kernel?

No. A reference encyclopedia entry states macOS is a proprietary Unix operating system derived from OPENSTEP for Mach and FreeBSD, with the XNU kernel incorporating large parts of the FreeBSD kernel — not the Linux kernel. The remaining retrieved items concern unrelated software or Linux itself and settle nothing about macOS's kernel.
