How to Fix Keyboard Type Issues on Your Mac

If you’re using a Mac, you might encounter a situation where your keyboard isn’t behaving as expected. This often arises from the computer not correctly recognizing the type of keyboard connected. Macs typically support three keyboard layouts: ISO (used in Europe), ANSI (common in the U.S.), and JIS (standard in Japan). Each layout has its unique differences, which can lead to confusion if your Mac does not identify your keyboard type correctly.

Here’s how to troubleshoot and fix keyboard recognition issues on your Mac:

Step 1: Understand Keyboard Types

• ANSI: The layout commonly used in the United States and parts of Asia and Latin America.
• ISO: Features one additional key compared to ANSI, and it has a vertical Enter key.
• JIS: This version has various unique elements, making it different from both ANSI and ISO.

Common Key Mapping Issues

When a Mac fails to recognize the keyboard type, you might notice that some keys are switched. This problem usually affects:

• The key directly below the Escape (ESC) key.
• The key to the right of the Left Shift key.

Step 2: Attempt the Automatic Fix

Apple provides a method to specify your keyboard type. You can follow these instructions for guidance:

1. Go to Apple Support for detailed help.

However, if this method doesn’t work or the Keyboard Setup Assistant does not appear, don’t worry! You can try the manual method below.

Step 3: Manually Reset Keyboard Preferences

To reset your keyboard settings manually, perform the following actions:

A. Delete Configuration File

1. Open Finder and navigate to your Mac’s main drive.
2. Go to the Library folder.

3. Locate and delete the file named com.apple.keyboardtype.plist.

   Alternatively, you can use the Terminal to remove this file:

   1. Open the Terminal app.
   2. Type the following command:

      sudo rm /Library/Preferences/com.apple.keyboardtype.plist

B. Launch the Keyboard Setup Assistant

After removing the configuration file, you’ll want to run the Keyboard Setup Assistant to set things right:

1. Go to System Settings > Keyboard > Change Keyboard Type.

   Or you can launch it directly through Terminal:

   sudo open /System/Library/CoreServices/KeyboardSetupAssistant.app/Contents/MacOS/KeyboardSetupAssistant

Step 4: Follow Setup Instructions

The Keyboard Setup Assistant will guide you through the process. Typically, it will prompt you to press the key next to the Left Shift key. If it doesn’t recognize that, try pressing:

• The key below the Escape (ESC) key.
• The first key next to the key to the right of Left Shift.

Finally, select the layout that corresponds to your physical keyboard—whether it be ANSI, ISO, or JIS.

Conclusion

By following these straightforward steps, you should be able to resolve any keyboard layout issues on your Mac. This guide helps you to identify your keyboard type and reconfigure your Mac to ensure smooth typing. If you continue to face problems, consider reaching out to Apple Support for further assistance.
