Hello, forum! I would like some help installing El Capitan on my 2008 Macbook Pro 4,1. I am currently running fresh install 10.7 (Lion). I have the El Capitan dmz and MacOS Extractor. When I try to install the patch on my external hard drive (320GB free, freshly formatted with Mac OS Extended (journaled)), Mac OS Extractor fails almost instantly. I am very new to Macs, but would love to have an OS in which I can update Google Chrome and install Office 2016. I am finding myself supporting Mac's more and more at work, so it would be nice to actually know what I am doing. Thanks.
