What is Erase Assistant?
If you have owned, given away, or sold an iPhone, you are likely familiar with its convenient feature, Erase All Content and Settings, which restores it to its original state.
However, the Mac platform only had this feature briefly, requiring a time-consuming process involving manual logout, disk erasure, and macOS reinstallation.
With the release of macOS Monterey, Apple introduced Mac’s version of Erase All Content and Settings, known as the Erase Assistant.
This tool simplifies resetting your Mac to its factory settings and erasing all data before reinstalling macOS with just one click.
However, there are instances where users encounter an error message stating, “Erase Assistant is not Supported on This Mac.”
This error indicates that the Erase Assistant feature is incompatible with your Mac. Specifically, it suggests you use an Intel-based Mac without the T2 Security Chip.
To address this issue, consider alternative methods for erasing your Mac or upgrading to a compatible Mac model that supports the Erase Assistant feature.
Ensure your Mac meets the requirements and stays informed about the latest updates to enjoy a seamless user experience.

The Erase Assistant is a recent addition to Mac’s features, designed to facilitate the erasure of a Mac without requiring a visit to macOS Recovery.
You may avail of the Erase Assistant on your Mac, provided you meet the following criteria:
- You have an Apple silicon-based Mac (M-series chip) or an Intel-based Mac with the Apple T2 Security Chip.
- Your Mac runs macOS Monterey (or Ventura) or a later version.
If you are unsure whether your Intel Mac includes a T2 security chip, the following list of Intel-powered Macs is compatible with Erase Assistant:
- MacBook Air [Retina; 13-inch; 2018, 2019, 2020]
- MacBook Pro [13-inch; 2018, 2019, 2020]
- MacBook Pro [15-inch; 2018, 2019]
- MacBook Pro [16-inch; 2019]
- Mac Mini 
- Mac Pro 
- iMac [Retina 5K; 27-inch; 2020]

You must explore alternative methods to reset your Mac, such as employing Disk Utility to erase all data and reinstall macOS.
How to Check Manually Whether Your Mac Has a T2 Security Chip?
