On my work place and at home I have networks using a proxy. For security reasons (it is correctly filtering most form of web based attacks), I don't want to remove it or to modify an healthy network architecture.
On Lion, it was possible to correctly install or recover MacOS X with the following receipe.
I'm actually using the wireless network to reach the Internet through my web proxy. My web proxy IP address is:
The port used to access web proxy in this case is:
Commands entered within the menu
Utilities > Terminal:
networksetup -setwebproxy Wi-Fi 10.0.0.1 3128 off networksetup -setsecurewebproxy Wi-Fi 10.0.0.1 3128 off
off argument means no proxy authentication needed.
Mountain Lion, this setting isn't working.
If I start
Safari from the Installer (with the Installer Help
Utility), I notice that any web access is going through the proxy,
but it is limited to Google locations services. Something as simple as:
doesn't go through the proxy.
I know easy workaround, but I would like to stay on a secure network for things as important as a fresh OS install.
I'm looking for further analysis of what may be blocking this
normal network access specific to
Mountain Lion installer.
