    I have two MacBook Pros, one Late 2008 (model 5,1) and one Early 2011. I use the Early 2011 MBP primarily. I decided to install OS X 10.8 on the Late 2008 MBP first, to test it out. The result was not promising. The Late 2008 MBP used to have OS X 10.6 on it, and the upgrade to 10.8 made it considerably slower.

    Everything is slow. Even starting System Preferences, with no applications running, takes like 5 seconds.

    My Early 2011 MBP has OS X 10.7 on it (which the Late 2008 never had), and at this rate I am afraid to upgrade it to 10.8.

    Do you think 10.8 will cooperate better on my Early 2011 MBP, because it is more recent hardware?

    Did anyone else find that 10.8 made their Mac much slower? Is there anything you found that helped?

    Thanks.

    Give it a day to index everything. Mine took a little bit to settle in, but all my Mac's fly on ML. That said, I have nothing older than 2010.

    OS X Mountain Lion runs really snappy on my Late 2009 under-specced Mac mini. You really shouldn't have any issues running on your MBP.

    It actually ran horribly slow on my 2011 MBP until I did a clean install... perhaps that's what you should do. A full clean install, and then manually move your iTunes/iPhoto libraries back into place, along with your files in your home folder.

    That did the trick for me - on both my 2011 MBP and my Mac mini.

    Doing a clean install sounds like a pain.

    Also, can you perhaps give me a link to instructions for how to do a clean install? Just in case. Thanks.

    my 2007 MBP runs just fine with ML 10.8..I don't see any major slowdown at all and I have no idea if the index was done before. :apple:
