Java programs are annoying to use on mac, so I bundled it and a python script into a standalone .app file so that it can be installed and launched directly from the command center like a normal application. (assuming you have python3, and java installed already)
If anyone wants to update or improve it here is the script that I used.
If you want the application to have an icon. Just put a png file next to this script, and run it. It should spit out the proper icns file. You can than just drag the icsn file next to the scripts above, and run the make script again to give it an icon

This will bundle an "ns-usbloader.jar" and run.py script in root into a .app file

python_script = "run.py"
# Step 1: Create the macOS application bundle structure
print("Creating macOS application bundle structure...")
os.makedirs(macos_dir, exist_ok=True)
os.makedirs(resources_dir, exist_ok=True)
# Step 2: Copy the Python script, JAR files, and icon into the bundle
print("Copying Python script, JAR files, and icon...")
shutil.copy(python_script, resources_dir)
for file in os.listdir():
if file.endswith(".jar") and "ns-usbloader" in file:
shutil.copy(file, resources_dir)
# Copy the .icns file if it exists
if os.path.exists("AppIcon.icns"):
shutil.copy("AppIcon.icns", resources_dir)
else:
print("Warning: AppIcon.icns not found. The app will use a default icon.")
# Step 3: Create a shell script to run the Python script
print("Creating shell script...")
