    After installing Leopard, my CPU usage has been continually stuck at 100%. I'm using an iBook G4, and I did a clean install, using Migration Assistant to copy over files/settings.

    The process that seems to be using the most CPU right now is "installdb", but others (including iCal) were doing the same earlier.

    same issue

    Yeah, my CPU is around 80% all the time with constant disk activity. I have a G5 @ 1.6GHz

    I have video issues as well. Spotting all over the place. Nice job Apple....

    Now, now, just because you are having spotty video and 80-100% CPU usage does not mean it is a definite problem with Apple. It is easy to always blame the install, but since most people installing on G4 and G5 are not having spotty video and crazy CPU usage, it sounds more likely that the issue is with what was on your system before the upgrade, such as corrupt .plist files or other configuration files. I would first try making a blank Preferences folder and renaming your current Preferences folder to see if these applications start running normal with NO cpu issues... then you can start trying to track down the corrupt config file.

    I had zero problems before the 10.5 upgrade. I reinstalled my ATI drivers and that fixed the video issues. However, most graphic animations are terribly slow. I would assume 256mb of vRAM is sufficient, is it not?

    How long have you been having a problem, it can take a few hours from the first boot for spotlight to reindex the drive and for things to return to normal.

    Yeah, initial spotlight database building is going to tax the system, also if you setup TimeMachine, some people have said systems with large files are continuing to backup all the time, so you may check into that.

    For anyone it might help, I eventually traced my problem to some sort of OmniGrowl/iCal glitch.

    I just started having this issue after 1 week in leopard. No ical usage.
