Key Remapping For Mac

Mar 12, 2019 In this article I want to demonstrate the way I remap the keyboard on GNOME based Linux distribution (like Ubuntu or Fedora) in a way to mimic the macOS behaviour. At the moment only X.Org display. Maybe you just checked for mac key remapping:). If this worked for you, please consider marking it as the accepted answer. – alex Sep 7 '09 at 10:57. Oh, by the way, glad it worked for you:) – alex Sep 7 '09 at 10:58. Found my exact case! It means I am not the only one with this weird mapping problem - Apple should listen to users. May 27, 2020 To remap a key, click the Add button and choose your keys from the two columns. The left column denotes the key you'll press (for example, the Caps Lock key) and the right column denotes the.

Technical Note TN2450

In macOS Sierra 10.12, we introduced a new way to keyboard key remapping. This document will discuss the various ways to do so.

Introduction

Under macOS Sierra 10.12, the mechanism for key remapping was changed. This Technical Note is for developers of key remapping software so that they can update their software to support macOS Sierra 10.12. We present 2 solutions for implementing key remapping functionality for macOS 10.12 in this Technical Note. The command line hidutil tool is useful for executable scripts. macOS applications can use the IOHIDEventSystemClient API to achieve this functionality. The scope of the key remapping function applies to all users and will remain in effect so long as there is an active keyboard service. Key remappings are lost when the system is restarted or if the keyboard service is removed (for example when the last keyboard is disconnected.) No special privileges are required to use key remapping.

Scripting Key Remapping

Keys can be remapped via the command-line tool hidutil. For example, use the hidutil command-line tool to remap the 'A' key to the 'B' key as shown in Listing 1. The map array consists of two key/value pairs that contain the source (HIDKeyboardModifierMappingSrc) and destination (HIDKeyboardModifierMappingDstKey) of the key remapping. The keys take a hexadecimal value that consists of 0x700000000 or’d with the desired keyboard usage value (see Table 1 for usage values).

Listing 1 Remapping keys in a script

A script can check the key remapping state by using the hidutil command-line tool as shown in Listing 2. A null result indicates that there are no key remappings active.

Programmatic Key Remapping

The IOKit HID APIs can be used for key remapping. The user will provide a dictionary of key remapping that the HID event system will apply to the keyboard.

Listing 3 : Key Remapping using IOKit HID APIs.

Key Table Usages

Table 1 presents a list of keyboard usages and their usage IDs for use in key remapping. This list is from the USB HID Usage Tables Specification, Section 10 Keyboard /Keypad Page.
