Se formattiamo e reinstalliamo OSX attraverso la modalità di recupero, scaricherò e installeremo l'ultima versione di OSX o useremo la versione esistente? Lo sto chiedendo perché ho notato che sta scaricando alcuni file durante la reinstallazione.
Dai un'occhiata ai seguenti link:
Informazioni su recupero di macOS
Da quest'ultimo link:
Start up from macOS Recovery
macOS Recovery installs different versions of macOS depending on the key combination you press while starting up. Hold down one of these combinations immediately after pressing the power button to turn on your Mac. Release when you see the Apple logo or a spinning globe.
- Command-R - Reinstall the latest macOS that was installed on your Mac, without upgrading to a later version.1
- Option-Command-R - Upgrade to the latest macOS that is compatible with your Mac.2
Shift-Option-Command-R - Reinstall the macOS that came with your Mac, or the version closest to it that is still available. Requires macOS Sierra 10.12.4 or later.
- If you're selling or giving away a Mac that is using OS X El Capitan or earlier, use Option-Command-R to make sure that the installation isn't associated with your Apple ID.
- If you haven't already installed macOS Sierra 10.12.4 or later, Option-Command-R reinstalls the macOS that came with your Mac, or the version closest to it that is still available.
