Generally speaking, the depreciation lifetime of a computer system these days is about 3 years.
From a practical point of view, it usually becomes unrealistic to support obsolete systems that are more than twice that old —
If you use Aurbach & Associates products and have obsolete computer systems, you need to consider our long-range plans.
As of the v3.6 release of Grady Profile, we no longer support computers running Mac OS 9. Support for OS 9 and the Classic Environment have bee removed from the release kits.
As of the v3.7.x release of Grady Profile, we only support computers running Mac OSX 10.4.11 or later.
If you are running Mac OSX 10.7 or greater, you must use Grady Profile v3.7.2 or later. If you have not received this version as part of your current maintenance/support package, please contact Aurbach & Associates immediately.
As of the v3.6 release of Grady Profile, we no longer support computers running Windows 2000NT.
We test and support our software on Windows XP and later systems. We always test on fully-patched versions and no longer support versions which are not fully patched.
If you do not regularly upgrade your Microsoft operating system to the current patch level, we very strongly recommend that you reconsider your policies, particularly since these upgrades are available without charge.
