How to Reset Mac: Complete Guide

This guide will explain how to reset your Mac, an operation useful for solving slowness or malfunctioning issues. Although Macs are generally stable, they may require a reinstallation of the operating system or a complete disk formatting to return to proper functioning. The guide will cover different situations, including reinstalling macOS without losing data and applications, complete disk formatting, and preparing the Mac for sale.

Before starting, make sure you have enough time and a fast internet connection, as several GB of downloads will be required.

Preliminary operations: data backup

Before resetting the Mac, it is essential to create a backup of your personal data. This will allow you to restore the data in case of problems or if you intend to transfer your Mac.

• Archive the backup on an external disk or a USB flash drive with capacity equal to or greater than that of the Mac's disk.
• If you intend to restore the data on the same Mac or another Apple computer, use Time Machine, the built-in backup system. Time Machine allows you to take a "photo" of the operating system and restore the entire state of the computer.
• For files stored only on the Mac's disk, you can manually copy them to the disk or USB flash drive.
• You can also create backups of app data and settings on iCloud via the System Settings menu > [your name] > iCloud.

If you are thinking of restoring your Mac and transferring it, you can use the macOS Migration Assistant to transfer data, settings, and apps to another Mac, Windows PC, Time Machine backup, or external disk.

• Open System Settings from the Apple menu.
• Go to the General > Transfer or Reset sections.
• Press the Open Migration Assistant... button and follow the on-screen steps.
