Hi The subject sounds rather ot, but I guess normal apple users wouldn't be able to answer this, since they are not dualbooting.
Well, I've downloaded the MacOS X Combo update via the system update tool, and afterwards, you are requested to reboot. To this day, I got it right. But today, I managed to forget to press Alt, and after clicking reboot it booted right into debian.. (I'm a good manager, no?) Ok, so far what was going on. Now the question: is the reboot needed to do some postinstall work whilst start up, or is it just the old joke, well, you've installed something, please reboot, otherwise it won't get loaded? Because, e.g. for a firmware update, you have to reboot since the updating process actually happens during the restart phase (or slightly after). So, has it been a mistake to not reboot into MacOS X, i.e. there is some temporary setting which triggers some special operations during the first reboot after an update, or is it just there that the newly installed stuff gets loaded, and it doesn't matter if you reboot into debian first.. I wouldn't be concernced normally, but the Combo update also fixed some security issues, and I am quite about security! -- Hope someone has some insight, would be very thankful! All the best, Andi
