Changed HDD from old Mac to new. Machine ID?
So i shifted from an old macbook pro 15" to a macbook to still be able to work. I took the hdd from the pro and put it in the macbook. Now my question is, will the machine id or the mac address change?? Just... wondering. because i've got a lot of wifi routers already saved and getting the passwords to a few of them is going to be a pain in the wrong place. Thank you!
