  1. @willie g

    That may be just a result of (1) a lot more Macs being sold and used, which means that there will be more bug reports getting back to Apple which are then fixed and (2) more resources at Apple to fix things that in the past they may have just ignored.

    Of course it could be (3) sloppier coding to begin with that needs to be fixed.

    I will be an optimist and go with the first two options.

  2. Doesn’t appear to work for Mid-07 MBPs — gives me a “you don’t need this” message when downloading / installing from Apple AND it won’t appear in Software Updates list.

    So, if anyone has successfully applied this update, please advise on:
    – how
    – which MBP you have

    Thanks!

  3. Successfully applied the firmware update to my MBP purchased in Dec.’07. New ROM is MBP31.0070.B07.

    Haven’t changed back my sleep options as it just scares me.
    Does anyone know if this solved that issue?

  4. Its becasue they are getting SO sloppy….

    try calling Applecare! it takes freekn 45 minuites to get ahold of someone- and its GUARENTIED to be a freeking Ghandi in India!

    Oh yea- and production of high-end computers in China does not work. I spent 6500 on my laptop and the little chineese girl that put it together messed it up and its had 3 logic boards….
