lgf: rebooting mac in safe mode to clear system caches

lgf: there are mischiefs to be cured: "And here’s a tech tip for any graphics geeks who work on a daily basis with Adobe’s CS3 suite of design applications. I was using Fireworks CS3, my main tool for doing everyday graphics chores like cropping, resizing, etc. when suddenly I got the spinning beach ball of death; a ‘busy’ cursor that wouldn’t go away, and a frozen application that needed to be forcibly quit. And we all know how painful that can be. What’s more, the same thing happened in every one of the CS3 apps. Restarting didn’t fix it. Repairing permissions didn’t fix it. Deleting preferences files didn’t fix it. Searching the web yielded nothing. Oh noooo. The solution in this case, and something worth trying on a Mac OS machine whenever you have this kind of weird problem, was to boot up in ‘Safe’ mode, while holding the Shift key. It turns out that this not only does a Unix ‘fsck’ command and fixes any disk problems, it also flushes all of the system caches. It takes forever to start up, because it checks the whole startup disk, but after finishing the startup and logging in, if you then restart in normal mode—voila! Your pilikia is all pau."
