On here I will run though the basic steps of getting Mac / OSX / Apple operating system on to a Lenovo ThinkCentre E73. I have currently got 10.10.1 which is Yosemite running on mine. But will be adding instruction so your able to put Mavericks on. I am currently at present using Chameleon as my boot loader but will be wanting to work out how to install Clover. (Both Legacy / UEFI). I’ll also be running though how to update the operating system successfully as well.
