Howdy folks, I bought a secondhand Macbook Pro 13 (2012) a while back and the guy I bought it off somehow managed to make 'About This Mac'/'System Report' display incorrect hardware information. The system I bought was supposed to be an i7, 16GB RAM, 500GB SSD but once I updated to the latest version of El Capitan upon returning home, 'About This Mac' and 'System Report' both displayed conflicting hardware info. I have since confirmed via both the serial number and system diagnostics that my machine is an i5, 8GB, 128GB SSD. Do any of you know how he did this and whether or not I can fix it without having to wipe my machine? I'm in the middle of a college course and I can't afford to have to do a clean install at the minute as I have a lot of software installed that I use on a daily basis. The attached screen captures were taken by me today and should explain more clearly what I'm talking about. Thanks in advance for any help. I'd love to figure this one out.
