    I am very new to Macs in general. I've used one for a few years at work and finally switched over my home system in May. I have a Mac Pro OSX 10.5.8, 2.66 GHz Quad Intel Xeon with 8 GB of Ram. I also have an upgraded graphics card. My software is limited to Adobe Creative Suite CS3, Neo Office, and Logic Express. Not much else.

    I've looked for anything that I can discern in my panic log, but I really cannot make heads or tails of anything in here.

    I've had 6 Kernel Panics since Dec 2, 09, the most recent being earlier today.

    Here's the whole panic log from the most recent and I apologize in advance for posting the whole thing. I'm not sure what is relevant and what is not:

    Looks like Safari did it. Try downloading the newest version from the Apple website and reinstalling it.

    Thanks much! I will try this, although the first time I had a Panic I updated all software (including Safari) and it has happened since then. But I'll try it anyway.

    Safari has been always at least been open when a Panic has happened for me so that makes sense - but I pretty much always have Safari open to some degree.

    Downloading updates now.

    So my Safari was totally up-to-date at the time of my most recent Kernel Panics (as I thought). What else can I do at this point?

    For now I'll probably contact Apple since I'm still under warranty and use Firefox or something if I intend on doing any actual work.

    follow the usual protocol of repairing disk permissions and resetting safari. if that still doesn't work, download the full installer from apple for the latest version of safari and install it over the top of what you have, even though its the same version. hopefully that will help.

    after actually looking at it it might be the pace.kext: com.paceap.kext.pacesupport.leopard 5.7.1

    try unloading it or removing it from your system or startup items to test if thats it (its not an apple one).

    Could you please elaborate on what steps to take to do this? I don't feel comfortable doing this unguided. I also don't really no where to begin.

    Might be the newest Flash beta 2

    Recently the newest Flash beta 2 caused a kernel panic and very unstable Safari behavior in general. My machine is a 2008 2.8 Ghz MP. If you have the beta version from Adobe Labs then you should try removing it with the official Adobe uninstaller and install the latest stable version.
