An OSX app to control the backlight on a CM Storm Devastator USB Keyboard

Introduction

The CM Storm Devastator Keyboard is a great keyboard save for one shortcomming.... The backlight does NOT work on OSX. The keyboard backlight is mapped to the Scroll Lock Key, and unfortunately this key is not really used or mapped in OSX.

Many people have tried to piece together a working solution, but most are far too technical for average users. Because of this, I have decided to make a simple OSX app that will allow a user to toggle the backlight of the CM Storm keyboard.

How It Works

Follow the instructions bellow to the install the application. Once installed you need to grant the application access to control your computer.

This may sound scary, but this permission is required so you can press Shift + Scroll Lock to toggle the backlight now. This project is open source, so feel free to compile it yourself instead.

In the top right corrner of yoru system tray, you will see "CM: On/Off" to represent the keyboard backlight status.

Installation

1. Download this zip
2. Extract the CMStorm.app and copy it to ~/Applications/ directory
3. Run the CMStorm.app binary
4. You will be prompted to enable accesibility, press Open System Preferences, and press the checkmark next to CMStorm to enable access.
5. Relaunch the CMStorm.app binary, and you should be good to go!

Usage

Press Shift + Scroll Lock to toggle the backlight

macOS Sierra compatibility?

I tried to run the app under Sierra, and it failed to load up in the menu bar. Accessibility was granted, and I can't see any indication that something is failing.

Wondering if you tested it out?

Don't show in top panel

First thank you for the project.

I followed steps to install your software

give enough perms (accessibility and keyboard monit)

but looks like nothing is happening. Already restart my computer and reinstall things but still not working.
then I tried to search inside the project

/CMStorm.app/Contents/MacOS/CMStorm

/Applications/CMStorm.app/Contents/MacOS/CMStorm ; exit;
➜ ~ /Applications/CMStorm.app/Contents/MacOS/CMStorm ; exit;

2374 segmentation fault
am I doing something wrong?

MacOS Catalina 10.15.7 version

Doesnt work for me

Followed the README, double clicked the app after adding it to the privacy & security portion, then nothing
