    Hi,

    Basically I'm having trouble downloading updates, etc.
    When I try Software Update I get 'Software Update could not expand the package correctly' - I've already searched this and found nothing useful that remedies the problem.
    One promising solution was to download directly from the Apple Support page, however when I try this the download begins initially but then I notice the kb/sec rate steadily deteriorate until it stops and the download closes. A .dmg file appears in the Downloads folder, but is obviously not as big as it should be, and upon opening it I get 'The following disk images failed to mount... : No mountable files systems'.
    This happens when I try downloading the most up to date Security Update/Safari 5/VLC 1.1.3 - these are the only things I've tried so far...
    I'd appreciate any help/suggestions.

    Running OSX 10.5.8 / 2.4Ghz Intel Core 2 Duo / 2GB 800Mhz DDR2 /iMac 8,1

    Additional - tried downloading through Software Update again, this time got error along the lines of 'download interrupted due to timeout' and cancelled as a result, my coneection was stable though (as far as I know since I don't babysit the download as it happens) - does the screensaver cause this? Should I deactivate the screensaver and all power-saving options when downloading?

    Definitely try deactivating the power save feature first and see how it goes. Then, if you are connected through Wireless, try switching to wired, and vice-versa if the other way around. If you have both, disconnect the wireless and just use the wired connection first.

    You might try to do a speedtest at http://www.dslreports.com/speedtest and see if that gives you any hint as to issues with your connection. I imagine it's okay if you can browse, stream video, etc., while online.

    Also, if you have a BitTorrent client running, pause or stop it when trying to update to make sure it's not hogging your bandwidth.
