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
