I have a Early 2011 Mackbook Pro, currently running "OS X 10.9.5 (13F1911)". I have previously installed a "Crucial MX100 512 GB SATA 2.5-Inch 7mm Internal Solid State Drive CT512MX100SSD1", and "Crucial 16GB Kit (8GBx2)". I was under the impression that I was unable to install new Mac OS software because it would cause issues. Do you have any opinion on this? Any help thanks.
