Reset Mac button missing

Hey there CD0,

To clarify, are you trying to erase your Mac back to factory settings? If so, the settings might vary based on the current macOS installed. This feature will need macOS Monterey or later. To update, use these steps:

Before installing new software, it's a good idea to back up your Mac.

1. From the Apple menu  in the corner of your screen:

• Choose System Settings. Then click General in the sidebar, and Software Update on the right.

• Or choose System Preferences. Then click Software Update.

2. If Software Update finds new software, click the Update Now or Upgrade Now button to install it.

3. Enter your administrator password, if asked. During installation, your Mac might restart, and you might see a progress bar or blank screen several times.

If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only updates and upgrades that are compatible with your Mac.
