That's certainly not what <http://developer.apple.com/documentation/
Performance/Conceptual/Accelerate_sse_migration/migration_sse_C/
chapter_3_section_3.html> says:
SSE3 is an optional hardware feature on MacOS X for Intel. If you
wish to use SSE3 features, you must detect them first
Perhaps you mean SSE2:
Similar selectors exist for MMX, SSE and SSE2, but since those are
required features for MacOS X for Intel, it is not required that
you test them before using those vector extensions, in software
intended solely for MacOS X for Intel
