I have a 15” Macbook Pro purchased in December 2008 which is still running (believe it or not) OS X 10.6.8 (Snow Leopard). I have finally decided to upgrade to 10.11 El Capitan (probably when the first point release ships) and would very much like to do a clean install of 10.11. I am familiar with the way a clean install could formerly be accomplished since I was able to do a clean install of Snow Leopard some years ago without any great difficulty. However, since—as with most OS X releases since Snow Leopard—El Capitan is not available on disc the clean install process—involving a USB flash stick, Terminal and other things— is now considerably more complex than it once was. I have looked at several articles on the Web regarding how to do a clean install of El Capitan and frankly they all seem incredibly complex to me. I am into my 70’s now and I’m afraid not as capable of learning new things as I once was. I was wondering if someone out there could provide me with a simple, clear, step by step process—perhaps using something called Diskmaker X. As mentioned previously, I have already looked at a number of sites-as well as several youtube videos— with articles explaining or demonstrating the process none of which was transparent enough for me to have the confidence to do a clean install myself. Maybe I could take my computer to a local Apple store and one of the Geniuses could do it for me. Don’t know. Any advice, instructions or suggestions would be greatly appreciated. Thanks in advance.
