Click the Apple menu and select About this Mac. Check for a line that begins with “Chip” and ends with a chip name, like Apple M1. If you see this, you have an Apple silicon processor. If you don’t see a “Chip” line, but do see a line beginning with “Processor” that includes an Intel processor name, you have an Intel processor.
Apple silicone: Press and hold the Power button until you see a hard drive with a gear. Click the gear, select Continue, and then sign in with your Apple ID if prompted. Intel: Press the Power button once, and then press and hold the Command + R keys until you see the Apple logo. If you’re prompted to sign in, follow the on-screen instructions to do so.

If you have an Apple silicon processor and have used Disk Utility to add volumes to your drive, you’ll see other volumes under “Internal” (besides Macintosh HD). You should delete each of these volumes before you continue—select the volume and click the minus sign to do so. Skip deleting other volumes now if you have an Intel processor—you’ll do it later.
If you have an Apple silicone processor, click Erase Mac and Restart to continue. If you have an Intel processor, you’ll be given the chance to erase other volumes after erasing Macintosh HD. If any other volumes exist, select them and click the minus sign in the toolbar to delete them.
