SPSS may generate incorrect results on Intel-based Macs

SPSS has issued a warning that its statistical software may generate incorrect numerical results when running under the Rosetta emulation environment on Intel-based Macs.

A support document states:

"SPSS does not support the use of any existing version of SPSS for Mac OS X on the new Intel-based Mac hardware, including SPSS 11.x or 13.0. The use of the Rosetta emulation software interferes with the numerical calculations in SPSS. We therefore are unable to support any version of SPSS on Intel-based Macintosh machines."

In addition, SPSS 13.0 prevents installation directly onto Intel-based Macs.

A company official says that an Intel-compatible version of SPSS for Mac OS X -- SPSS 15 for Mac OS X -- will be released in the second quarter of 2007.
