Apple has released new firmware updates for several machines, but offered no meaningful explanation of what the update does. Apple’s note is maddeningly cryptic:

This update fixes several issues to improve the stability of [MacBook Air. Macbook, MacBook Pro, iMac] computers

The updates have sparked consternation in the Mac web world. At sites like the MacRumors forums, more than 200 commentators are asking, “What does it do?”

The updates are for:

MacBook

MacBook Pro

MacBook Air

iMac

Apple also released an update for the Aluminum Keyboard, but this one at least includes a meaningful description of the changes:

This firmware update addresses an issue with the aluminum Apple Keyboard and the aluminum Apple Wireless Keyboard where a key may repeat unexpectedly while typing.

    Really though, what’s wrong with the simple description given? Is it just not technical enough for us? How about:

    where $stability = 1; make $stability >1; return “satisfied”

    Could also be in response to the hack on the Air.

    Update Bonanza:
    The Google search just put you into the ‘not for your eyes’ category. This forces you to make a ‘Google Account’ to change the preferences — just some added hoop to hop.

    When I downloaded to my 2 mos old MacBook 2.4ghz, a message popped up saying the install wasn’t needed.

    Weird.

    Yeah…same with my 2mo old MacBook Pro…the updated must only be for the newly released machines.
