MacBook Pro new hard drive
I have decided to replace my hard drive to try and get some degree of speed back into my mid2012 model MacBook Pro.
I have done a time capsule back up and have the new sdd ready to be installed, but one things I can’t get to the bottom of is what do I need to do to reinstall the OS.
Do I need to download an installer for the OS and run that, or
Do I replace the hard drive and then can I format it and then download the OS from the recovery mode on boot up?
I welcome all advice!
MacBook Pro 13", macOS 10.14
