PAZ Software Refund Policy:
Refunds are limited to 50%
of the total software order price.
Please consider:
Specialty scientific software has a very small market.
Macintosh OS has a small portion of the scientific software market.
Filling orders takes time. The software price pays for that time.
If the you ordered the software thinking that it would run under Windows,
then you should be happy getting 50% back.
MacOS is posted all over this site.
