See https://opensource.apple.com/source/xnu/xnu-7195.81.3/osfmk/i386/lapic_native.c.auto.html Additionally, an upcoming commit will validate the icr values written by the guest. Older intel processors allow some different combinations than the newer ones. AMD documents that only the newer combinations are allowed. So, bumping the version allows us to avoid a differentiation between AMD and Intel. Intel documents that newer processors than the P6 are using the new combinations. Sadly, Intel does not document which apic version belongs to those processors. Linux identifies newer apics by a version larger or equal to 0x14. Intel and AMD allow apic version between 0x10 and 0x15. So, using 0x14 seems to be fine.
