about this mac

Mac OS X 10.5 (or greater) is a 64-bit operating system. Intel Core 2 Duo, Intel Xeon, and PowerPC G5 are 64-bit processors. However, 64-bit Stata for Mac is available only for 64-bit Intel-based Macs.

All currently shipping Macs have a 64-bit processor and a 64-bit operating system.


Linux users should issue the uname command. Depending on the platform, you may see:

[cph@gaylord ~]$ uname -a
Linux gaylord.stata.com 2.6.11-1.27_FC3 #1 Tue May 17 20:24:57 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
[cph@caddo ~]$ uname -a
Linux caddo.stata.com 2.6.9-5.0.5.EL #1 SMP Fri Apr 8 14:20:58 EDT 2005 ia64 ia64 ia64 GNU/Linux

Linux tango.stata.com 2.6.10-1.771_FC2smp #1 SMP Mon Mar 28 01:10:51 EST 2005 i686 i686 i386 GNU/Linux

In the above listing, 'gaylord' (x86_64 GNU/Linux) and 'caddo' (ia64 GNU/Linux) are 64-bit compliant. 'tango' (i386 GNU/Linux) is only a 32-bit platform.
