    I've got the AppleCare, looks like I'm covered for another two years.

     

    Interesting my download just failed on my External Hard Disk, giving the same 'Failed to verify InstallESD.dmg' error!

     

    It can't be a faulty external hard disk as well!

    No I would not suspect that. Are you doing this over WiFi? If so that is a Very bad Idea. Any drops in the WiFi signal can/will cause the download to fail.

     

    What part of the world are you? Do you have some type of Firewall running on your router?

     

    My download and install just finished and the system is booting for the first time. So it is not a server error in my part of the world.

     

    Next option is you have failing hardware. Like the RAM has gone bad. As they say S.h.i.t happens.

     

    Best to take it to Apple and have the whole system checked out. We could go round and round with this. RAM, Hard drive cable, faulty logic board or a host of other stuff.

    I am using Wifi, but surely 1/25 installs must have went through without dropping the signal. I'll try now with it connected via Ethernet to see if it makes a difference, not holding any hopes though!

     

    Any built in boot tool I can use to scan my systems hardware?

    Lets HOPE it was the WiFi.

     

    Good Luck with Ethernet.

    No luck with Ethernet cable, same error :(.

     

    I also get a '6002d' error when trying to launch Online Apple Hardware Test - a quick google suggests a possible RAM issue. Either way, the problem seems hardware related, I'll see what Apple store have to say.

     

    Thank you very much for your help Shootist007 and others, have a Merry Christmas!

    Just an update guys, took it into the Apple Store today...

     

    Hard disk checked out okay, I suggested RAM failure, so after a new pair of RAM sticks, it successfully reinstalled so RESULT!

    Glad you got it fixed and hopefully it wasn't at your expense.
