    Hello,

    I'm new to this OS, which is a iMBP 13" (2009 revision). I'm experiencing abnormal bootup. The bootup screen display a prohibition sign upon bootup after installing Security Update 2010-001 for Snow Leopard. There is no error message I can write down nor excessive fan noise coming out from the laptop.

    Thanks for your help

    Tony from New Zealand

    What to try. I am reasonably confident that the archive and install will fix the issue without needing to go the more excessive route of the erase & install.
