# Apple Music ALAC Downloader |
||||
Original script by Sorrow. Modified by me to include some fixes and improvements. |
||||
|
||||
## How to use |
||||
1. Create a virtual device on Android Studio with a image that doesn't have Google APIs. |
||||
2. Install this version of Apple Music: https://www.apkmirror.com/apk/apple/apple-music/apple-music-3-6-0-beta-release/apple-music-3-6-0-beta-4-android-apk-download/. You will also need SAI to install it: https://f-droid.org/pt_BR/packages/com.aefyr.sai.fdroid/. |
||||
3. Launch Apple Music and sign in to your account. Subscription required. |
||||
4. Port forward 10020 TCP: `adb forward tcp:10020 tcp:10020`. |
||||
5. Start frida server. |
||||
6. Start the frida agent: `frida -U -l agent.js -f com.apple.android.music`. |
||||
7. Start downloading some albums: `go run main.go https://music.apple.com/us/album/whenever-you-need-somebody-2022-remaster/1624945511`. |
