Purchased a Macbook Pro (Late 2013, 8GB, 256GB) and the owner reset it to factory. The current Administrator is a profile he made to let me test it with everything in English. I want to wipe the test profile and start fresh so when I boot up recovery (CMD + R) to access disk utility and reinstalling Yosemite the entire menu is in Chinese! If the system is set to English when he reset it to factory, why is recovery still in Chinese? How can this be changed? Thanks, would appreciate all the help.
