Common Mistakes to Avoid

1. Incorrect Kernel Extension Installation

Reason: Installing the wrong kernel extension or a corrupted one can lead to system instability and prevent graphics acceleration from working correctly. This is often due to downloading from untrusted sources or incomplete installation.
Solution: Download the kernel extension from a reputable source and ensure a complete and proper installation, following all instructions carefully.

2. Ignoring System Requirements and Compatibility

Reason: Attempting to use a graphics acceleration solution that's not compatible with your specific Mac model or macOS Ventura version. This can lead to system crashes and other serious issues.
Solution: Verify that the graphics acceleration solution is explicitly supported by your Mac model and macOS Ventura version before installation.
