How to reset your MacBook or MacBook Pro?Apple Tips
Back up your data before resetting your MacBook ProEven if you never intend to reuse your data, make sure to back it up. The last thing anyone wants is for something important to be permanently deleted. If you need to restore your data after formatting, MacBook Pro users should use a time machine to back up their MacBook user data.
1. Open the Time Machine on your Mac from the Applications folder or by clicking on its icon on the dock.
2. Connect the external hard disk drive to your computer and select it by clicking Use as Backup Disk.
Important: You can use iCloud to back up your MacBook user data, and you can't back up your Mac OS or applications in the iCloud. In contrast, the time machine backs up everything.
3. Click on the Time Machine icon in the menu bar and then click the Back Up Now option in the Time Machine menu.
Now, wait for the backup process to complete and then disconnect your external hard disk drive from your MacBook.
How to factory reset MacBook Pro?Now that you have backed-up all your information (user data), you can start the process of resetting the MacBook Pro without any fear. Before resetting your Mac computer, make sure you have the fastest internet connection so you can easily download the latest version of macOS after the reset process. If possible, connect your MacBook directly (Internet Wire) to your router or modem.
Important: You should always reset your MacBook to factory settings before selling or disposing of it. It is not enough to drop the files in the trash and empty them because there are still ways to restore the file even after doing so. The factory reset process ensures that your data is completely erased from the machine and cannot be recovered.
1. Turn off your MacBook.
2. Restart the Mac in recovery mode. There are three ways to do this, and each requires a keyboard match.
First, press and hold the Command + R key as soon as the MacBook boots up. This key combination opens the standard version of the recovery mode and lets you install the latest version of macOS.
Second, press and hold Option + Command + R key as soon as the MacBook boots. This key combination gives you the option to upgrade to the latest version of macOS that is compatible with your MacBook machine.
Third, press and hold Shift + Option + Command + R key as soon as the MacBook boots. This key combination installs the version of MacOS that came with your MacBook or the closest version available if it can no longer be downloaded to the OS (Operating System).
It doesn't matter which method you use, and yes, hold down the keys until the Apple logo appears.
3. In the window that appears, click on the Disk Utility.
4. As soon as the Disk Utility window opens, click View, and then click Show All Devices.
5. Select the drive you want to erase. It will probably be titled "Macintosh HD".
6. Click on Erase.
7. Quit the disk utility and go back to the previous window.
8. Click on the Reinstall macOS.
9. Now follow the steps that appear on the screen. Allow enough time for installation to complete.
Note: This process can take several hours to complete. macOS files will be downloaded during this process and the download process depends on your internet connection.
10. When the OS (operating system) is installed, the Macbook restarts. Enter your Apple ID and username when asked to do so.
11. If you reset (format) your MacBook Pro to sell it, press Command + Q key to turn off the machine.
