The disk format should be Mac OS X extension (Journaled). GUID Partition Map. Partition name: bootpartition (this name is used in this example, you can customize it, please note that bootpartition in the terminal command below should also be changed to your customized name).
When you install a new major version of OS X, or after some time has passed, it is a good idea to do a clean install (that is, to erase the disk you are installing OS X onto as part of the installation process).
That will make your Mac run blazingly fast for a few months or more, and many people report that it fixes longstanding problems they’ve had too.
It used to be common practice to occasionally run a clean install, and then manually migrate all the files and settings over in order to get a completely fresh start. However, it has been shown in recent times that in the vast majority of cases if you simply run a clean install, then duplicate your old home folder to your new disk, you will get all of the same advantages as a clean install followed by manual migration, with a small fraction of the effort.
Here is the clean install procedure which can be performed at least every time a new version of macOS is released:
At this point, after a reboot and some minor adjustments (the Dock may not have your previous configuration for example, if you did this while logged into the same user account as you just updated), your new OS should be indistinguishable from your previous one, while being faster and smaller due to reduced clutter.
