Hello everyone. My company recently acquired an iMac 21.5" with ML 10.8. I can only connect to internet through our proxy server. If I want (and I will) to make a clean install, through recovery partition, it allows me to choose the network, but not to configure my proxy settings, so I'm unable to connect to the internet and therefore, to Apple's servers in order to download the OS. Since 10.8 came with the machine I can't download it to be at hand. Or can I? Not in the Mac App Store, at least. Is there anyway to solve this problem? Thank you in advance, for your time.
