The Mac M2 chip is Apple's second generation of custom silicon for Mac devices, which was announced on June 6th, 2022, at the WWDC (Worldwide Developers Conference). It follows the powerful M1 chip, which was released in 2020. According to Apple, “The M2 chip brings more speed to everything you do — whether you’re editing a video for class, collaborating on a business plan, or streaming a show while you shop online. And with all-day battery life, you can leave the power adapter at home.” The M2 is made with TSMC’s (Taiwan Semiconductor Manufacturing Company) N5P process and contains 20 billion transistors, a 25% increase from the M1.
Apple devices like MacBook Air (MBA), MacBook Pro (MBP), iPad Pro, Mac Mini, M2 Pro, M2 Ultra, and the upcoming Vision Pro all come with M2 chips.
Let us now discuss the steps required to wipe a Mac with an M2 chip using BitRaser Drive Eraser software to permanently wipe data beyond the scope of recovery.
Note: The steps for erasing a Mac with an M1 chip are similar to those for wiping a Mac with an M2 chip. You can use the instructions below to wipe Mac devices with either an M1 or M2 chip.
For ease of your understanding, we have divided this KB into 4 stages:
Stage 1: How to Find if Your Mac Has an M2 Chip?

Now, that you know your Mac device has an M2 chip, let us look at the steps to download the ‘Cloud Variant Mac: BitRaser Drive Eraser’ that allows you to create a bootable drive for erasing M2 Mac, as well as other Mac devices with M3, M1, M1 Max, M1 Pro, T2 & those with Intel processors.
Stage 2: How to Create BitRaser Bootable USB for M2 Mac?
Before making a BitRaser bootable USB, make sure the following requirements are met.
Key Requirements:
- Operating System: macOS
- Internet: Wi-Fi or Ethernet
- RAM: 8 GB (recommended) / 4 GB (minimum)
- USB Device: Minimum 32 GB or more to create BitRaser bootable. (USB 3.0)
- Full Disk Access: The software requires Full Disk Access
Step 1: Post-purchase of BitRaser Drive Eraser Mac, you will receive an e-mail with the link to BitRaser Cloud Console.
