    First post ever, sry for the English as not my first language

    I have this MBP 15' since mid 2009 (unibody)

    I would like to upgrade the snow leopard to Lion since the Xcode4 only
    supported by Lion.

    But the Lion makes a lot of concerns, A friend of my got a late 2010 iMac

    21' (i3 processer and 4GB ram ). She installed the Lion which got the common

    WIFI issue and slower than snow leopard.

    If this will happen to me or worth like happened to others (WIFI, Heating,etc)

    Any solution to this or the update already fix these thread??

    I've got Lion on a 2006 C2D iMac and it runs like a charm. On my MacBook I've disabled the local time machine backup and that helps.

    I thought there was a Snow Leopard version of Xcode 4. There is no Lion version of Xcode 3 though.

    I'm running Lion on a 2008 unibody MBP, and a 2006 iMac, with no problems...

    I upgraded my MBP from 4GB RAM to 8GB, and it made a huge difference, but even with 4GB, I could do everyday stuff on it. My iMac has 2GB RAM, and sometimes runs slow, so I'd suggest having at least 4GB RAM if you upgrade to Lion.

    4GB Ram, then it should be fine.

    I've had Wifi problems in Leopard and in SL (they eventually vanished in some SL update). I haven't had any problems so far with Lion. Often luck is involved in these kinds of things.

    Thx for your helpful info


    So ram is the main bottleneck for the performance?


    My friends iMac 2010 with lion , the WIFI shows ok, but no internet connection.
    which is very annoying
