Hi all, Please forgive me if I have posted this in the wrong thread or anything. I am a noob and have limited computer knowledge (apologies on this front also ...). I have an old Mac that I am preparing to sell – a 2008 model that originally shipped with Lion. Following instructions online, I erased the hard drive and now need to install a fresh copy of Lion (or a later OSX, I don't mind, but I just need to install some kind of OS!). Judging by the look around the Internet I've already had, this is problematic because, as far as I can tell, Lion isn't available any more via the App store and when I go to install it from the window I get on my 2008 Mac, it simply says to try again later. Again following advice on the internet, I then tried to create a bootable copy of Lion on a USB drive (following this: http://osxdaily.com/2011/07/08/make-a-bootable-mac-os-x-10-7-lion-installer-from-a-usb-flash-drive/). However, my current Mac runs El Capitan, and therefore has a version of Disk Utility that doesn't offer the 'Restore' function needed. I'm therefore at a loss as to what to do next. I did find a thread discussing what to do using Terminal, but since I don't really know what I am doing and didn't really understand what the command lines specified would do, I didn't want to go copying and pasting lines into Terminal all willy-nilly. Can anyone help me out? I'd just like to be able to get an operating system running on my old Mac. Thanks so much in advance.
