Hi, friends.


I've proved that statement several occasions before looking at Numbers, but it's true. I restart the computer (White MacBook 13") and restart it again (by the way, I don't know why the second restart improves computer speed more than the first one) and then I open mail, work on it, close it; open iTunes, play some tunes, close it; open Numbers, work on it and the fan starts making noise all the way and from then on it doesn't stop until I close Numbers. I feel how even the poor computer rests once I close Numbers. I also use Netbeans to develop in Java; well neither Netbeans nor Safari, not even Adobe Flash on Safari starts the fan for so long time and so noisy. Fortunately, I work on a table, so I can avoid burning my limbs.


Anyone of you have experiment something alike? Some advice?


Thank you.

MacBook, OS X Mountain Lion

    You're correct. See this thread. Don't be fooled by the fact that the question is marked as Solved.


    I suggest that you Provide Feedback via the Numbers menu, contact AppleCare if you have it, see an Apple Store Genius if you are close to one.


    If you have to work on a Numbers document, try to rest the "mouse" pointer off the table. The pointer has to be over the table, not the window as a whose, for the cpu to race.

    You don't have to wait for the fans to start. You can look at the CPU load in Activity Monitor. It will jump to something on the order of 75% when the mouse hovers over a table. I was at first concerned that the problem was an interaction with third party apps. That happens, and even if it's only a small percentage of owners, they show up here and you think it's a universal problem. But in this case, you can walk into an Apple Retail Store and demonstrate the problem on the first computer you find.
