# # 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 if you have questions.
- For troubleshooting, join the OpenCore Patcher Paradise Discord Server
  (opens new window) and see our Troubleshooting Page.
