Erase MacBook Air 2015 for a sale
Hello. I am selling my MacBook Air early 2015 model with El Capitan installed.
I want to erase all personal data and reset the system for the new owner. I cannot for the life of me see how to do this after checking disk utility, the manual and forum. How, please? Thank you all.
MacBook Air (13-inch, Early 2015), OS X El Capitan (10.11.6)
