I am using a mac notebook with iTunes 10.6.

I have an iPod 4g and a iPad 2.


When I connect the devices to iTunes, it asks for upgrade, then check and just stalls checking, and goes into some infinite loop or something.

When I tried using the settings -> general -> system upgrade on the devices, the iPod starts to download then says "An error occured downloading ios 5.1"

The iPad can't even connect to check for an upgrade.  "An error occured while checking for an upgrade"


My sister has an iPod with iTunes on a Windows laptop in the same house.  I helped her with it and it worked perfectly to download and install.  I can't use the windows to install ios 5.1 to mine since the PC laptop is older and limited memory to backup my iPod or iPad.


An older Windows can outperform a newer mac notebook, iPad 2 AND an iPod 4g?


Is there a third way I can try to get the newer ios 5.1 installed on my devices?

iPad 2 Wi-Fi, iOS 5.0.1, also iPod Touch 4g
