Mac users need to think about security, too
Apple's approach to security can be a little bewildering at times. It's a well-trumpeted aspect of the OS, marketed in detail on the website. Mac OS X has integrated smartcard support and Apple has certified the OS under the Common Criteria guidelines; a section of Apple's developer site is devoted to the subject of security.
This page is really just a list of resources for research economists who want to use a mac rather than a Windows or Linux machine. Yes, the software you rely on does run on a mac. Indeed, Apple's operating system, OS X, is actually built on top of BSD UNIX, and so numerical software you run under Windows should do quite well under OS X as well. The notes here relate to PowerPC and Intel software. At this point, the introduction of versions of packages that run on the new Intel-based macs as well as the PowerPC based macs is more or less complete. This list is not comprehensive, and is offered without any warranties or guarantees implied or otherwise. Caveat emptor.
