How do I use Disk Utility to format and erase the iMac’s hard drive during a reset?

Using Disk Utility to format and erase an iMac’s hard drive during the reset process involves several steps ensuring a clean and effective reset. To begin, users need to access Disk Utility from the macOS Utilities menu. They can do this by restarting the iMac and holding down the “Command” and “R” keys simultaneously until the Apple logo or a spinning globe appears, initiating Recovery Mode. From there, users navigate to the menu bar and select “Utilities” and then “Disk Utility” to access the Disk Utility window.

Upon accessing Disk Utility, users will find a list of drives and volumes connected to the iMac. They should select the internal hard drive of the iMac that requires formatting and erasing. Next, users click on the “Erase” tab, which allows them to choose the format for the drive, typically “Mac OS Extended (Journaled)” or the newer “APFS” format for macOS High Sierra and later versions. After selecting the desired format, users then proceed by clicking the “Erase” button, confirming their choice in a subsequent dialogue box. Disk Utility will then begin the erasure process, wiping the drive clean and preparing it for the macOS reinstallation or factory reset.

It’s crucial to note that formatting and erasing the iMac’s hard drive using Disk Utility permanently deletes all data on that drive. Hence, it’s recommended to ensure a backup of essential data exists on an external drive or cloud storage before performing this operation. Following these steps in Disk Utility offers a relatively simple process, but users should proceed with caution as formatting and erasing the wrong drive could lead to data loss or drive corruption. An active internet connection may be required for certain macOS versions or for reinstalling macOS using a bootable drive, ensuring the availability of the necessary installation files during this process. If encountered with any error messages or difficulties during the formatting process, seeking guidance from Apple Support or professional assistance may be beneficial, especially if users are uncomfortable performing advanced disk operations without an advanced degree of technical knowledge.

How to set up system preferences, language, and user account information after resetting the iMac?

After completing the reset on the iMac, users initiate the setup process, which involves configuring system preferences, language settings, and user account information. Upon restart, the iMac begins the Setup Assistant. Users will first be prompted to select their preferred language. They can navigate through these initial setup screens using the mouse or trackpad to select options and proceed. Subsequently, users are directed to choose their country or region, followed by connecting to a Wi-Fi network. An active internet connection is vital during this step, especially for later macOS versions that require internet access to authenticate and complete the setup. Users can select their Wi-Fi network from the available options in the menu bar or enter network details if using a hidden network.

After establishing an internet connection, users proceed to configure system preferences such as setting the time zone and enabling location services if desired. The Setup Assistant then prompts users to create or sign in to an Apple ID account. If users wish to transfer data from a previous backup stored on an external drive or bootable drive, they can opt for this option at this stage. However, if users prefer a fresh start or haven’t backed up data externally, they proceed with creating a new user account. Users set a username and password, choosing their preferences for the login method. Finally, the iMac’s setup involves agreeing to the terms and conditions and configuring whether to enable Siri or allow iCloud features. Throughout this process, users should follow on-screen instructions and prompts, ensuring the iMac’s setup is tailored to their preferences and needs while ensuring a smooth transition post-reset.
