Formatting the new hard drive
Good Afternoon. Okay!
I just installed a new HD into my 21.5" late model 2013 iMac (the same HD the iMac came with, Hitachi). It was a lesson in patience, but i did it!
Now what? There is no disk to install, to get the operating system back like the older macs.
I do not want to back up anything, this will be a clean install period.
I want to give this computer to my niece since I have a new 27" iMac.
Can i just boot up with Command +R and reinstall Yosemite and follow the instructions?
Is this a good question?
