# What is OpenCore?

OpenCore is a sophisticated boot loader used to inject and patch data in memory, instead of on disk. This means that we're able to achieve a near-native experience on many unsupported Macs. 

We recommend viewing the [OpenCore Patcher Terminology Page](./TERMS.md) if you have questions.

For troubleshooting, see our troubleshooting pages below or join the [OpenCore Patcher Paradise Discord Server.](https://discord.gg/rqdPgH8xSN)
