So, here is the scoop. I'm running a 4.5 y.o. Powerbook (stats below) with the most current OSX version, and all up to date (well, until todays .3 release). I run permissions here and there, disk utility, fsck, and sometimes bring in other applications to help me do these things and a few others. My problem is that at this point my OS is slower than it should be. Yes, I know my computer is old and new apps will make it seem slow blah blah, but we're talking hangs on applications as old as my computer. Nothing sudden, it just dawned on me one day that when I got my computer and *insert old app name here* I was amazed how how fast and smooth it ran, and now that isn't the case so much. I suppose it could be down to a hardware issue, but I suspect that the software, after being written and rewritten to disk a million times has had a few bytes go missing. So, is there anything beyond the basic that I can check or do? Something that is pointless for a newer computer, but that might actually help on a computer my age? Defragmenting is supposed to be taken care of, but what about at this point in its life? Of note, I have never reinstalled the operating system because I don't like reinstalling everything and fixing up my settings again. If I can't take the time to organize my photos, I don't feel redoing my OS is in the works. But if that is a good option, or my only one, I may spring for it. Thanks for any and all advice!
