Safe updates, as well as bug fixes and workarounds, are now available in our Support section. We have released a couple of fixes for things like Time Machine as well as a fix for DHCP issues that some customers are having. Computers shipped as of today have all updates available preinstalled with Leopard. Please check our website regularly as we will begin releasing safe updates through the operating system's Automatic Updates and will require all of our existing users to download a small update manually and install it to enable this functionality.
