I’ve downloaded and installed Mac OS X Lion. I want to install the operating system on my mom’s Mac and I don’t want to have to re-download the ISO. Is there any (free?) alternative?
Another option is to copy the Lion Installation App from your Application directory to the other Mac using an external Hard Drive, a USB Stick or via File sharing.
CNET has done a review of Lion, and you can find the method to do what you seek here: http://reviews.cnet.com/8301-13727_7-20080989-263/how-to-create-an-os-x-lion-installation-disc/
