In this KB, learn the steps to erase M1 Mac machine or wipe Apple Silicon M1 Mac using BitRaser Drive Eraser Software.
The Apple M1 is a family of ARM-based systems-on-a-chip (SoCs) built by Apple Inc. Apple’s CPU and graphics processing unit (GPU) has transitioned from Intel to Apple silicon chips for its Mac desktops, and laptops (MacBook Air, MacBook Pro, Mac Mini, Mac Studio, Mac Pro), as well as its tablets. The built-in Apple M1 processor allows file-level encryption, automated data encryption, and password protection, giving the Mac the same robust security features as the iPhone.
Let us now see how to erase Mac devices with M1 chip. For ease of understanding, we have divided the KB into 3 stages:
Stage 1: How to Create BitRaser Bootable USB for M1?
Before creating BitRaser bootable USB you need to ensure that the below key requirements are met.
Key Requirements:
- Operating System: macOS
- Internet: Wi-Fi or Ethernet
- RAM: 16GB (Recommended)
- USB Device: USB 3.0 With a Minimum capacity of 32 GB to create BitRaser bootable.
- Full Disk Access: The application requires Full Disk Access.
Step 1: Post-purchasing BitRaser Drive Eraser, you will receive an e-mail with your BitRaser Cloud credentials. Using these credentials, you can download the BitRaser Mac Application from the support section of the BitRaser Cloud Console to create a bootable USB.
Note: The BitRaser Mac application initiates when a bootable USB is created using the ‘BitRaser USB Creator’ utility. With the bootable drive, you can erase Mac Machines that have Apple Silicon Chip like T1, T2, M1, M1 Max, M1 Pro, M2, or Intel chips.
Step 2: Once downloaded, drag and drop the application to install. The application requires ‘Full Disk Access’ to create a BitRaser bootable USB.
Steps to Give Full Disk Access:

Step 5: Select the USB drive from the dropdown menu, and click on ‘Create’ to make a bootable USB.

The software will prompt you with a warning message that all the data on the selected USB will be erased.
Step 6: Click on ‘Continue’ to begin the process.
Note: This is a time-consuming process and can take approximately 45 Minutes to complete.


Boot the Mac using the bootable USB that you created to begin the wiping process. You may encounter the following three scenarios when booting a MacBook M1 device due to the additional security protections in Apple devices with M1 chips.
Stage 2: What are the scenarios for Booting M1 Mac?
Scenario 1: The OS is Present, and the user knows the Mac admin password.
Scenario 2: The OS is Present, but you do not know the password.
