There, the Mac reaches out over a Wi-Fi or ethernet connection to download the relatively modest Recovery software, which then bootstraps the download of the full macOS installer.ДЄpple says Internet-based Recovery should happen automatically on supported models, and you should see a spinning globe when that mode is invoked while the download occurs.

However, thereвЂ™s yet another option: macOS Recovery over the Internet, which requires either a Mac model released in 2012 or later, or most 20 models with a firmware upgrade applied. When complete, it installs it and reboots, and places the installer in the Applications folder.

(Apple doesnвЂ™t document that, and I havenвЂ™t had to test that for years.)ДЇailing finding it, Recovery downloads the currently installed version of macOS (or OS X), which is about 5GB. In that mode, when you choose to reinstall without erasing the drive, my recollection is that Recovery looks for the current OS system installer on your startup disk in the Applications folder, and uses that. That allows you to run Disk Utility, reinstall or wipe and install the system, access Terminal for command-line functions, and so on.

Normally, you can start up a Mac while holding down Command-R to boot into what Apple now calls macOS Recovery. The article includes instructions on obtaining the installer, which might involve you having to use someoneвЂ™s else Mac to download it, if you donвЂ™t have a replacement Mac on hand yet.Д«ut if you canвЂ™t get access to another Mac or the necessary drive, itвЂ™s still possible to use a different Recovery mode on all recent Macs, dating back to 2010. We have instructions for making a bootable installer with macOS Sierra (as well as archived versions for several previous releases). Recovery lets you install onto an erased partition, but only if Recovery wasnвЂ™t erased, too!Д«ecause Recovery didnвЂ™t work, the fastest way to install fresh is to make or borrow a macOS installer on a USB flash drive or a disk drive.
