Q: Can't Verify OSX Mavericks Download

Installation of Mavericks fails and states that download is corrupt and to redownload from the App Store.  This is my 4th time deleting and restarting the download.  File is the correct size, intact, and in the applications folder.  Any help is much appreciated.  Even though I have Comcast Extreme 105, I hate burning the cycles on this.

    I had the same problem and this worked for for me:

    After downloading and deleting manually (drag and drop from the app folder to the trash bin) twice, I tried to do differently. I didn't delete the installation file and simply launched the App Store, went to Mavericks page and pushed the button "Download" at the upper left corner (where the price of the app is usually shown), even though the copy of the installation file was already on my computer (this time I didn't delete it before dowloading again). The download started and at the end this annoying pop-up window telling about the copy verification problem didn't show up. Now installing Mavericks. Maybe this is just a coincidence, but I suggest trying since noone here seems to propose another solution.

    Tell me if it works! And good luck!

    I tried this, twice, as well.  Did not help.  Error is still thrown.  I wonder if this has to due with an overloaded software verification service, but I have no way of testing that.

    People, people . . . The servers are way overloaded right now.  Wait til tomorrow, or even the next day.  There's nothing amiss with your computer.

    Same problem here.... I've tried deleting the installation file and redownloading Mavericks from the App Store almost a dozen times. Nothing seems to work.... I really don't know what to do. I've looked through several other forums and no one else is reporting this problem.

    No, this is an issue that could have been avoided if it is performance related.  There should be a 1:1 ratio between downloads and verifications.  There is no reason for a verification server to be overloaded.  This isn't a health care site ;)

    I get the same error when trying to install Mavericks and have tried about everything. I have downloaded this 5 gig installer about 5 times today already.

     

    I went so far as to reformat my drive, reinstall mountain lion, and try the Mavericks update on a brand new install. After that failed, I decided to get tricky and make a bootable Mavericks install USB flash drive. It fails with the same verification error.

    I am having same problem.   For those who can successfully run the install, can you get the SHA1 checksum for your installation?

     

    Open the terminal, and run this:

     

    /usr/bin/openssl sha1 /Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg

     

    I'm getting this:

     

    SHA1(/Applications/Install OS X Mavericks.app/Contents/SharedSupport/InstallESD.dmg)= 6e3b5d13ee73186945197b040ad44378b0a7af58

    I think you are wright.Because i have the same issue when trying to instal new iOS on release day every new version.

    Hope the servers are the problem,because i have it installed on other two machines(different IPs and ISP).

    Meanwhile it is very annoying.Tried 7-10 times

    Exactly the same problem here too. "This copy of Mavericks cannot be verified". I have tried the method described by 'Yarik.s' too and that didn't work either. Macbook Air (June 2013) i7 model with 8Gb RAM. The RAM checks out ok too.
