+### Notes about the macOS build:
+
+- The macOS version is packaged using PyInstaller into a standalone `.app` bundle, distributed as a ZIP archive.
+- Since this application is not signed with a paid Apple Developer Certificate, **macOS Gatekeeper will block it** on the first run (saying it "The application is damaged and can't be opened").
+  - **To fix this**: Either open the Terminal in the folder the app is in (or navigating with `cd path/to/folder`) and enter `xattr -cr Twitch Drops Miner (by DevilXD).app` or just type `xattr -cr ` (make sure to put a space at the end), drag and drop the `Twitch Drops Miner (by DevilXD).app` file into the terminal window (this will auto-fill the path) and enter
+- Persistent files (like `cookies.jar`, `settings.json`, `lock.file` and the `cache` folder) are stored inside the application bundle in `Twitch Drops Miner (by DevilXD).app/Contents/MacOS` (to access them Right-click the application and select `Show Package Contents`)
