Not all Mac users know what the Recovery Mode is and what it is for. Many users don’t even know this feature exists. To put it simply, the Recovery Mode is a dedicated partition on your hard drive housing a recovery image and a copy of your macOS installer. This partition is completely independent from the other partitions on your disk that even if you wipe your hard drive clean, it would still be there. The recovery partition is helpful in extreme cases where you might need to reinstall a fresh copy of your latest macOS or OS X.

Even if you format your drive and start from scratch, this partition remains intact and you can still reinstall your macOS, restore from a Time Machine backup, or repair your disk via Recovery Mode. The Recovery Mode makes troubleshooting a lot easier and faster because all you need to do is press two keys: Command + R.
