Here’s how to check the type of processor in your Mac.
- Select Apple Menu > About This Mac.
- You’ll see an item labeled Processor or Chip followed by its name. If it’s a chip, the name will read M1 Chip.
Below are the steps you’ll take to enter Recovery Mode for an Intel-based Mac or a Mac with Apple Silicon (M1 chip).
