Fix iTunes Error 9006

iTunes error 9006 may appear when attempting to download, restore, or update an iPhone or iPad. Typically you’ll see an iTunes error message that states something like “There was a problem downloading software for the iPhone. An unknown error occurred (9006).” or you’ll notice an “err = 9006” message alongside a stopped or failed download of an iPhone software update.

    Antivirus and firewall is often the problem for updates. Macs don’t need antivirus.

    Works for me! Thanks, after having trouble for quite a few weeks.

  3. Ormond Otvos says:

    Great. Download while connected to the internet with NO firewall or virus protection!

    What was that number of seconds from connecting to the internet and the first malware attack again?

    • Luis says:

      it says to disable just the firewall portion of the antivirus, not to completely disable the antivirus.

    • Ian T says:

      Antivirus software does not protect against Malware. That’s a big misconception. It also interferes with Mac updates because it thinks it’s an attack. Indeed, it can come bundled with Malware itself or be toxic to the Mac – think Mackeeper! If malware is the problem, install Ghostery and Adblock plus and use Malwarebytes Antimalware App (free) to get rid of any.

    • Edward Guzman says:

      Perhaps that is relevant with a Windows PC if you are browsing oddball things and downloading gibberish. But with a Mac or a Windows with careful browsing, you can avoid most junkware, malware, virus, etc.

      But you are missing the point here, which is to download the iPhone update with the firewall turned off, then install the iTunes update. Then you can re enable your firewall if you want. If the firewall is causing you download problems, what else are you going to do?
