Step 1: Check for macOS updates

Before configuring Boot Camp, it is critical to make sure that your Mac's software is up to date, which lessens the risk of encountering problems during installation:

1. In the menu bar, from the Apple menu, click System Preferences.
2. On the left, go to Software Center.
3. If there are updates for your computer, in the upper right corner of the window, click Update All.

   If you're prompted, enter an administrator's username and password, and if prompted, allow your computer to restart.

When your computer restarts, check for additional updates by repeating the steps above. Repeat the process until there are no new updates in System Preferences.
