Do I need a stable internet connection to proceed with the factory reset?

Yes, having a stable internet connection is crucial when proceeding with a factory reset on a 2017 iMac. While some steps of the factory reset process can be completed offline, an internet connection is required for certain critical tasks.

Firstly, a stable internet connection is necessary to download the macOS installer from Apple’s servers during the reinstallation phase. When you reset your iMac to factory settings, the operating system (macOS) needs to be reinstalled from scratch. This involves obtaining the most recent version of macOS, which is usually downloaded directly from the internet. Without a reliable internet connection, the download process could be slow, interrupted, or fail altogether, which would prevent the reinstallation of the operating system and render your iMac unusable.

Secondly, during the initial setup after the macOS reinstallation, your iMac may need to verify your Apple ID and iCloud account information. An internet connection is necessary for this verification process to ensure the security of your device and your data. Additionally, some applications and system components may require internet access to complete their setup or update procedures, enhancing the overall functionality and security of your iMac.
