以这个电脑音频频谱显示工具为例：https://github.com/1061700625/SpectraTray
使用Swift
不需要Apple Develop ID，推荐！
原理是通过swift来做一个启动器。
0、准备干净的环境。
python -m venv tray source tray/bin/activate pip install -i https://pypi.org/simple pystray pillow numpy SoundCard pyobjc1、创建原生启动器 App。
mkdir -p SpectraTray.app/Contents/{MacOS,Resources} mkdir -p SpectraTray.app/Contents/Resources/pysrc cp app.py SpectraTray.app/Contents/Resources/pysrc/ cp -R tray SpectraTray.app/Contents/Resources/tray cp SpectraTray.ico SpectraTray.app/Contents/Resources/2、写 Swift 启动器。
cat > main.swift <<'SWIFT' import Foundation import AVFoundation func runPython() { let bundleURL = Bundle.main.bundleURL let py = bundleURL.appendingPathComponent("Contents/Resources/tray/bin/python3").path let script = bundleURL.appendingPathComponent("Contents/Resources/pysrc/app.py").path let task = Process() task.executableURL = URL(fileURLWithPath: py) task.arguments = [script] // 完全后台（不弹终端） task.standardOutput = FileHandle.nullDevice task.standardError = FileHandle.nullDevice do { try task.run() } catch { } exit(0) } // 先触发一次麦克风权限（允许后 python 才能录到 BlackHole） AVCaptureDevice.requestAccess(for: .audio) { _ in runPython() } RunLoop.main.run() SWIFT swiftc main.swift -o SpectraTray.app/Contents/MacOS/SpectraTray3、写 Info.plist。
cat > SpectraTray.app/Contents/Info.plist <<'PLIST' <?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"> <dict> <key>CFBundleName</key><string>SpectraTray</string> <key>CFBundleDisplayName</key><string>SpectraTray</string> <key>CFBundleIdentifier</key><string>local.spectratray</string> <key>CFBundleExecutable</key><string>SpectraTray</string> <key>CFBundlePackageType</key><string>APPL</string> <key>CFBundleShortVersionString</key><string>0.0.2</string> <key>CFBundleVersion</key><string>1</string> <key>CFBundleIconFile</key><string>SpectraTray.ico</string> <key>LSBackgroundOnly</key><true/> <key>NSMicrophoneUsageDescription</key><string>用于捕获系统音频（如 BlackHole）并显示实时频谱</string> <key>LSApplicationCategoryType</key><string>public.app-category.utilities</string> </dict> </plist> PLIST4、去掉 quarantine。
xattr -dr com.apple.quarantine SpectraTray.app5、刷新图标。
touch SpectraTray.app6、启动 SpectraTray.app
