“Every month that Windows has been out. Every. Month.”
What do Apple and the Unix crowd do about security vulnerabilities?
Apple does what Microsoft -used- to do. They issue patches from time to time, mostly irregularly, when required by discovery of a new vulnerability.
Microsoft used to do that, but the much higher rate of vulnerabilities and thus patches for Windows (compared to MacOS) drove Windows datacenter and business IT managers crazy, because they have to roll out those patches after testing, to hundreds or thousands of client machines. Its impossible to do that irregularly, so Microsoft finally got pushed to do monthly patch releases (hence, Patch Tuesday, the second Tues of each month). Each Patch Tuesday typically has between half a dozen and 2 dozen patches rolled up into it.
Linux distros issue updates to their packages constantly, so its up to the user (or IT manager) to decide when to update their machines. Everything is in the open, no secrets, so its easier to manage piecemeal.
