Problems Downloading Mountain Lion



There have been several reports of people having problems downloading the latest vesion of the Mac OS - Moutain Lion.  I've had the same problem myself with my own and other MacBooks, an iMac and a MacMini. 

There seem to be two discrete issues when it comes to downloading the upgrade.   The first is an App store message that says:

"We could not complete your purchase.  The product distribution file could not be verified. It may be damaged or was not signed."

It seems that this may be caused, at least in some cases, by Intego Virus Barrier X6.  You will need to remove the antivirus completely, try the download again and now it should begin.  If it does, reload your antivirus.   DON"T FORGET THIS BIT!

The second issue happens when you are happily downloading the upgrade and it gets to 53.25 Mb and stalls.  

This is bit harder to get to grips with, but here is the solution.

Although I am a domestic BT Broadband user, I have a BT 2-Wire business hub which copes with the the dreadful rural telecoms infrastructure in my neck of the woods.   It seems that the 2-Wire is the problem.

Following a lead I found on the internet, I've just replaced the 2-Wire with a Netgear router and the problem has gone away.   The download is now well passed the 53.25 Mb level - 302.46Mb and counting.

Pity it is going to take an estimated 22 hours to complete the download though!

 Bottom line. If you are a Mac using BT Broadband customer, with a 2-Wire BT Hub, running Intego Virus Barrier X6 - you are probably a very unhappy bunny at the moment - unless you have found your way here!

Non-UK readers may wish to know that the BT Business Hub is a 2-Wire 2700 HGV as shown at the top of the page!
Having had some major problems with my own broadband service, I understand how others struggle to get help from BT.

There is a lot of good information out there, but it can be hard to find. So this blog is an attempt to pull some of it together, in one place.

It's a blog that really shouldn't be needed - if only BT and possibly other ISP's in the UK, provided useful customer support.
