got my MBP 13" on 26 Nov 2010, was working fine, but past couple of days downloading files from yahoo mail and the PDF's and jpg's images are all messed up. Then flash plugin was missing, so downloaded this again but the dmg can't be verified and is corrupted. So verified HD, no problems found?? Then tried updating software and the message is - The update "Remote Desktop Client Update" can't be saved. The update could not be expanded and verified. It may have been corrupted or tampered with during downloading. The update will be downloaded and checked again the next time that Software Update runs. - ??? how do I fix this.

MacBook Pro 13, Mac OS X (10.6.5)

    Welcome to Apple Discussions!

    Also, are you doing your downloads with the power adaptor plugged in or on battery? It's always safest to download software with the power adaptor plugged in, as you don't want your computer to run out of battery in the middle of a download.

    You might try downloading your updates just a few at a time, or even one at a time for long ones or ones requiring restarts, and repairing permissions afterwards. It might also be prudent to close all open applications and do the downloads when you aren't doing anything else.

    Good luck!

    I took my MB back to day one and I am still having corrupted downloads. When I try to do system downloads or individual downloads. With a system download it says SafariErrorDomain Error 1 or with an individual download of any thing like iMovie or iTunes it says that the image is corrupted.

    I am having the same problem with several computers (two iMacs and a MacBook), several Mac OS versions (Snow Leopard and Lion) on two differents Internet connections, is very fustrating I can't download iOS5 and XCode betas


    ¿Perhaps a problem with the Akamai network?  I'm in Spain.

    I have been seeing this intermitently with iOS updates and now with 10.7.3 updates - the download completes successfully but then the installer cannot complete because the file is "corrupt"


    I strongly suspect there is something wrong with the file distribution folks - perhaps some setting akin to not setting binary mode on an FTP transfer - or not seeting passive mode etc.


    Via software update on both a Mac Mini (client) and a Mac Mini Server - the update was about 700MB or so - and downloaded in under 3 minutes - but then failed to install.


    The (client) cobo updater from Apple wbesite directly is 1.2GB takes abotu 20 minutes to download. will know in about a half hour if that works.

    Direct Download of Combo Updater Seems to be okay on the client system - have not yet tried on the server.
