To install Spine on your MacBook Air with an M1 chip, you need to bypass the macOS security feature called Gatekeeper, which blocks applications from unidentified developers. Here are the steps to allow the installation:
- Open "System Preferences" on your Mac.
- Go to "Security & Privacy."
- In the "General" tab, you should see a message saying "Spine.pkg was blocked from use because it is not from an identified developer." Click the "Open Anyway" button next to this message.
- A prompt will appear asking if you are sure you want to open the application. Click "Open" to proceed with the installation.
This should allow you to install Spine on your Mac. If you encounter further issues, you might want to check if the application is compatible with Rosetta 2, which allows running Intel-based applications on Apple Silicon Macs.
