Where can I get a general description of what the spinning pinwheel may mean? I've been on MAC for about a year and just started seeing it once in a while for seconds at a time, usually at system startup.

Thanks so much

    Read: The Spinning Beach Ball of Death, by Dr. Smoke for a thorough explanation.

    It took a lot of searching for me to find this myself. Basically BootX is loading the kernel and device drivers. Was that the answer for which you were looking?

    Yes and no - I'm going to look at the information on all the links suggested but my basically naive quest is - does the pinwheel necessarily mean caution/problem/breakdown?

    No, it just means, "I'm thinking." If it does it for too long then you have to decide if it is still innocently thinking, or is trying to solve the question as to which came first, the chicken or the egg and won't talk to you until it has decided.

    Thank you Ferd II and Limnos - most appreciative - questions answered.
