In an ideal world, Mac OS X would never need security updates. However, given the reality that they are necessary, Apple issues Mac OS X Security Updates every month or two, not on a regular schedule. If Apple issued them more often, they would close security holes more quickly, but the workload for users to download and install the updates would be increased. If Apple issued them less often, they would leave security holes open longer, but the workload for users would be decreased. What do you think the ideal balance should be?
