I'm troubleshooting my brother's MacBook (purchased summer 2008), and I've got 14 individual panic logs from the past week. My main question is whether I should bother checking RAM/AirPort card or just simply do a clean install. I've backed everything up. I don't use the computer regularly so I can't tell you what he's been doing when it panics. But today while I was trying to back it up using my external drive (which works fine with my MBP), it panicked twice until I finally gave up with Time Machine and just dumped his drive contents onto my computer using target disk mode. For the panic log line that starts with "BSD process name corresponding to current thread:" I have 14 different panics with the following items: Deskjet Deskjet Deskjet coreservicesd launchd Deskjet kernel_task Deskjet ReportCrash kernel_task ManagedClient Deskjet Finder mds The last two (Finder and mds) were when I was trying to complete a backup using Time Machine. No other applications were open. The MB is running 10.6.3. It has a 2.4 GHz Core 2 Duo processor and 4 GB of RAM. I don't want to re-install Snow Leopard if it could be a hardware problem. But I don't want to drive two hours to the nearest Apple Store if a clean install would fix it. I'm looking for suggestions about where to go next. I do plan on trying the Apple Hardware Test CD when my brother brings me his CDs, but I wondered if anyone could explain the information from the panic logs and offer suggestions. I've spent several hours searching the web, but I can't find a good guide that tells me what those specific BSD process name words indicate. Thanks!
