How do I copy or back up my macHD
I'm going to replace my old 250 GB HD with a new 1TB HD. I need to copy or back up my old or current HD. I have an external drive, a Seagate 1TB HD. What do I need to do to move all my data, files and operating system from current HD to the external drive prior to removing the old drive and replacing it.
Is this a good question?
