    Upgrade to Mountain Lion-battery life?
    Hello all,

    I have lost the (Snow Leopard) install disks for my 2010 macbookpro and need to reinstall. I am debating between ordering the Snow Leopard or Mountain Lion disks. It would be nice to upgrade as long as I am reinstalling, but have heard that Mountain Lion absolutely kills battery life and in some cases of repeated upgrade/downgrades permanently wrecks the battery. I have no complaints with Snow Leopard but would be excited to try the upgrade if I could be sure it wouldn't drastically drop my battery life.

    What are your experiences with this? What would you recommend?

    Thank you all in advance for your help!

    First, Mountain Lion is not available on disk. It must be downloaded from the Mac App store. You can make a bootable flash drive before installing by using the Lion Disk Maker software. The latest update to Mountain Lion (10.8.3) has resolved the battery problem.

    No version of OS X has ever "permanently killed" a battery or battery life. There have been some semi-noticeable drops in battery life in some versions, but wherever you're getting your Mac info from, I would consider it the Fox "News" of computer information.

    "Fox News" as in the only truthful news agency? And by the way, the 10.8.3 update did in fact resolve the poor battery performance of some Mac portable machines.
