For those running MacOS X Lion, aka 10.7, it is now safe to install the 10.7.3 update. Apple switched from the context sensitive Software Updates version of the update (which is supposed to only install the components of the update that your computer needs) to the “Combo” version which contains everything for all currently supported Mac hardware. This makes for a bigger update, but a safer one.
Please plan to allow enough time for the update to download, connect yourself to the fastest network connection possible and for those with Macbooks, connect your Magsafe AC Power supply before installing.
If you are not running a Mac, or are not running MacOS 10.7 (Lion) please disregard this message.
