    Anyone having problems with boot time for ML? On my early-2011 macbook pro is taking ~1m30s witch is much more than SL.

    So how long is taking ML to boot in your mac? It's slower than SL?

    It is probably a good idea to backup your data and do a clean install with recovery hd

    All boot times have improved:

    Imac: 28 seconds

    MBA: 11 seconds

    MBP: 30 seconds

    These are boot to a useable state, not just the appearance of the desktop and dock.

    Obviously, the MBA comes out way on top due to the SSD, but overall boot times are faster.

    I have an early MBP 2011.

    There's a boot time? Something isn't right - try the clean reinstall suggested and see how it is then.

    My Mac Pro early 2008 original spec with 6GB ram

    SL = 31 sec
    ML = 48 sec

    But all apps seem snappier!

    Thanks!

    I will do a clean install on weekend then...

    For now it's ok, because all apps are snappier and I don't reboot my mac so often =]

    My 13" mid 2012 is also booting up noticably slower after the Mountain Lion upgrade.

    Could someone else with a 13" ML Macbook confirm on how long it takes you to boot? Clean install seem like too much work for me especially when I have a bootcamp Win 7 partition'

    I have a 2009 13" MBP, which boots and runs faster thanks to Mountain Lion, but that might have more to do with the fact that I did a clean install.

    If I'm not mistaken, doing a clean install with a Windows partition wouldn't be much harder than clean installing on a single partition hard drive; you'd just need to make sure you only erase the partition with Mac OS X installed on it when you boot from an ML .dmg and open Disk Utility.

    The boot time for my 2012 15" MacBook Pro w/ ML is 32 seconds. 2 seconds slower than it was with Lion.
