+## Patcher Warnings
+
+Since this patcher tricks macOS into thinking you're running a newer Mac, certain functionality may be broken:
+
+* Boot Camp Assistant.app
+  * We recommend running the assistant on a natively supported OS
+* Legacy Windows Booting
+  * Currently OpenCore cannot boot MBR-based installs, so Ivy Bridge and older Machines may not be able to see Windows in OpenCore's Boot Picker
