Recovery mode contains a powerful set of tools to repair or restore your computer in case of emergencies. It is particularly useful when your Mac doesn’t boot or in cases when the drives are corrupted or damaged.
When your Mac doesn’t boot and there is an inherent problem, ‘regular recovery mode’ is your first choice. This mode accesses the recovery partition that contains essential files to boot your system and reinstall OS. The recovery partition in this case is a partition that is already present on your computer.
However, if the drive has been severely damaged, recovery partition on your computer cannot be accessed and hence regular recovery mode cannot be used. In such cases, recovery files are accessed through the internet and this is called ‘Internet Recovery Mode’.
How to start Internet Recovery Mode
- Boot your Mac and when you hear the chime, press Command + Option + R. In cases, when the normal recovery is unavailable, press Command + R to automatically open internet recovery mode.
- You will see a globe sign stating that internet recovery is starting
- Then select your Wi-Fi network, enter the password and hit Enter
- The system will connect to Apple’s severs and download necessary files. Once the recovery files are downloaded, you will be presented with a list recovery options menu. In the menu, you will have 4 options that are listed below.
- Restore from Time Machine Backup
- Disk Utility
- Reinstall OS X

Internet Recovery mode options explained
Restore from Time Machine backup: Select this option when you have a backup of your system in Time Machine and you wish to restore it.
Disk Utility: In case your computer is not working or if your drive is corrupt, you can use Disk Utility as a first choice. The First Aid feature in Disk Utility is a powerful feature that repairs most types of corruption issues.
Reinstall OS: However, if your drive is severely corrupt or damaged and cannot be repaired using Disk Utility, you can use the Reinstall OS X option to reinstall your operating system completely. Of course this is an extreme step, but if nothing works, this should be your last resort.
What about the data after OS reinstallation?
Sure, OS reinstallation resolves most kinds of corruption issues and damage due to crash etc. But what happens to your data after reinstallation of OS? If you have a backup, there is no problem. But if you don’t have a backup, all your data will be lost. But, luckily there are data recovery programs that are available for this problem.
Remo Recover is the perfect data recovery software for Mac to recover lost data after reinstalling OS. All your partitions and data are recovered safe and sound. The hierarchy and structure is maintained after recovery, so you don’t need to worry about finding your file/s in thousands of recovered files.
There are data recovery tools available, but as they say, being prepared for emergencies is always better. You never know when disaster happens and when you’ll need to reinstall OS. So, always have a backup of your data at all times. If you are using a Mac, even better; you have access to Time Machine, so be sure to use this feature and be safe.
