I'm using a MacBook Pro with a Swedish physical keyboard but with a U.S. layout defined in System Preferences. However, the tilde (~) and plus-minus (±) keys seem switched. The following key combination should produce a ~:

Because the mapping in System Preferences says so:

But it results in a ± symbol.

It seems these two keys (± and ~) are switched somehow. How do I make them work as shown in System Preferences?

    The 2nd picture appears to be showing some kind of hybrid between US ANSI & UK ISO layouts. US keyboards have no key to the left of Z, UK keyboards do. Tilde is to the left of Z on UK, but left of 1 on US. You might be better using a UK map instead.

  • @Tetsujin you're right. But switching to British makes no difference, the keys are still swapped. Jul 1, 2018 at 9:19

    Ah, ok, darnit. I'm out of ideas, sorry.

    The 2nd picture is in fact the US ISO layout, what you are supposed to get when US is used on an ISO keyboard with the extra key. Aren't the keys also swapped when you are NOT holding down SHIFT? Jul 1, 2018 at 9:33

Here’s a solution that does not use any external tools.

Run this in Terminal.app:

hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000035,"HIDKeyboardModifierMappingDst":0x700000064},{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardModifierMappingDst":0x700000035}]}'

Now try your ~ and ± keys: they should be switched around.

Problem is, this fix will only work until the next restart. To make it permanent, you have to automatically run it on system load.

You can do that in three Terminal.app commands:

  1. cat << 'EOF' > ~/.tilde-switch && chmod +x ~/.tilde-switch
    hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000035,"HIDKeyboardModifierMappingDst":0x700000064},{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardModifierMappingDst":0x700000035}]}'

    (This is all a single command.) This stores the script from above in an invisible executable file in your home directory, ~/.tilde-switch.

  2. sudo /usr/bin/env bash -c "cat > /Library/LaunchDaemons/org.custom.tilde-switch.plist" << EOF
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">

    (This is all a single command.) This creates a system task: ‘run the file from step 1 on every startup.’

  3. sudo launchctl load -w -- /Library/LaunchDaemons/org.custom.tilde-switch.plist

    This loads (activates) the task from step 2.

Steps 2 and 3 will prompt for your password. And now, your ~ and ± keys are permanently switched.

Note 1

This appears to work not only on the MacBook's build-in internal physical keyboard, but on the external keyboards as well.

Note 2

To undo the switching script (not the three steps), here’s the reverse script:

hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000035,"HIDKeyboardModifierMappingDst":0x700000035},{"HIDKeyboardModifierMappingSrc":0x700000064,"HIDKeyboardModifierMappingDst":0x700000064}]}'

Note 3

To undo the three steps:

sudo launchctl unload -w -- /Library/LaunchDaemons/org.custom.tilde-switch.plist; sudo rm -f -- /Library/LaunchDaemons/org.custom.tilde-switch.plist ~/.tilde-switch

    In case of: Invalid property list error you may need to replace <key>Program</key> with <key>ProgramArguments</key><array><string>${HOME}/.tilde-switch</string></array>

    I've tried the fix and it works great! Thanks a lot! Just a small note - it actually affected all my devices, so it works for external keyboards as well (thankfully) and not only for the built-in keyboard as mentioned in the post. Jun 30, 2020 at 14:06

    @MiroslavNedyalkov I was probably confused on that part when I first wrote the answer. Edited, thanks.

    Worked for me! Why not putting it however, in .bashrc? Jul 24, 2020 at 21:46

Using Karabiner Elements, you can add a "Simple Modification" as follows:

"Karabiner Elements Preferences" window, "Simple Modifications" tab, "Target Device" dropdown is set to "Apple Internal Keyboard / Trackpad (No manufacturer name)". Two rows are shown in the configuration table. The first row contains "From key": "non_us_backslash", "To key": "grave_accent_and_tilde (<code>)". The second row contains "From key": "grave_accent_and_tilde (</code>)", "To key": "non_us_backslash".

Basically, you need to know that the name of the § (±) key in Karabiner's configuration screen is non_us_backslash

In my case, I used this method specifically for the built-in keyboard, leaving my external keyboards unchanged.

  • Great software. Love it. Thanks a million

Here is Apple documentation with table containing all the keys and corresponding hexes. https://developer.apple.com/library/archive/technotes/tn2450/_index.html

Initial state is no active key remappings:

hidutil property --get UserKeyMapping

Remap ~ to §± one way:

hidutil property --set '{"UserKeyMapping":[

Swap them both ways:

hidutil property --set '{"UserKeyMapping":[

For removing any remappings back to initial just pass an empty array:

hidutil property --set '{"UserKeyMapping":[]}'
  • that's perfect, it worked, and I didn't need to install any apps that require weird permissions! It would be amazing if you included how you discovered the key codes too. Thank you

  • @SudoPlz Good question. So there is a link in my initial comment. Open that page, scroll down to Table 1 List of keyboard usages and their usage IDs., and here you can find Keyboard Grave Accent and Tilde 0x35 and Keyboard Non-US \ and | 0x64. Jul 15, 2021 at 10:49

  • Amazing, thanks for the good solid simple answer and clarification. I read the link and understood both solutions, but didn't go through till the key codes :D Thanks!

Building on CBlew's solution, one can do without the extra file (which wouldn't work as-is for a multi-user system). Write a plist file like

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
      <string>{"VendorID": 5426, "ProductID": 579}</string>

then set it with sudo launchctl load -w -- /Library/LaunchDaemons/com.example.setkeyboard.plist.

For generating the hidutil invocation I am using this simple Python script.


I had this problem switching to a new macbook (with external keyboard). I fixed it by removing my input source (dvorak) and then clicking on "Change keyboard type..." and getting it to identify my external keyboard again (as ISO european). I then re-added my input source and the ~ and ± keys were swapped back and in the correct place.

  • didn't work for me unfortunately.

    @user3575439's solution was what worked for me on Dell hackintosh laptop. On macOS Monterey 12.0.1 goto System Preferences → Keyboard → Change Keyboard Type and change to ISO.

I had the exact same situation (Nordic keyboard, US layout). The problem is that macOS thinks you're using the wrong "type" (ISO vs ANSI) keyboard. To fix it:

  1. Open keyboard settings
  2. Click Change keyboard type... at the very bottom
  3. The Keyboard Setup Assistant will pop up and ask you to press the key to the right of the left shift key
  4. Do not press that >
  5. Instead, press Z

macOS will now determine that you're using a standard US keyboard.
