hi all,


I use a macmini, after upgrading to 10.8.4, it becomes a little slow when bootup, and freezes when login window displays. According to the console log, it takes munites to "hidd: Timeout waiting for IOKit to be quiet"


does anyone knows what's going on?

    Try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application unistaller. For each disable/delete, you will need to restart if you don't do them all at once.

    Resetting NVRAM solved my problem too.  I was getting long (10min) boot times and the IOKit message on the console.  Thanks Hepoi.
