    I'm not sure I understand your response. You mean there's no output in the Terminal window? In that case, please post a screenshot of the window showing what you did.

    I'm asking for the text that appears in the Terminal window, not in the Console window.

    I posted some instructions for you to do something in the Terminal a few messages back, but I think that was a bit too ambitious for your experience level.


    Instead of trying for a precision fix, I suggest you use the Apple Support approach. Back up all data, then boot from your installation disc and reinstall OS X. When the system reboots, run Software Update. You may have to run it more than once to get all available updates. Your data should be unaffected.


    If you have any doubts about how to carry out this procedure, don't. Make a "Genius" appointment at an Apple Store for assistance.


    If there's no improvement after the reinstallation, you may need to do something more drastic: a clean reinstallation. For that, you really do need someone more experienced to help you in person.

    Erase the drive and reinstall everything from scratch.

  • Denise Clark111 Calculating status...

    Hi Linc, I have tried your first instuction again and it has worked. So the window that came up is titled system.log

    size 27.87 GB on disk

    created thursday 13 sept 2012


    I tried your second instruction and it wouldnt work for me, it's me!

    what do you reckon?

    I am backed up to time machine on an external drive WD which is kept only for time machine. I think I could do an erase and install, I did it before my update to snow leopard.

    I'm not sure it's a good idea to just restore my cleaned disc with the time machine back up in case it reinstalls the same problem, so i was planning just to put certain things like mail and contacts and certain applications (just the ones that came with snow leopard). Or, do you think it will be ok just to reinstall everything?

    I could delete the extra applications then back up after and reinstall that back up.

    I'd appreciate your thoughts linc, thanks!

    I forgot to mention, that the size of my log file is staying the same now for a couple of days.

    I'll assume that you're the original poster in this thread, though you're not using the same ID. I don't know which instructions you're referring to. You marked your question solved. Is it?
