+# Master PDF Editor Patch
+
+Bypasses license validation for **Master PDF Editor 5.9.98** using inline hooking via [tinyhook](https://github.com/Antibioticss/tinyhook).
+
+Supports both **Apple Silicon (arm64)** and **Intel (x86_64)** architectures.
+
+## How it works
+
+The dylib hooks `MainWindow::ValidateLicense` to force license flags, then calls `QDocTab::SetRegProgram` to complete activation.
+
+## Build
+
+```sh
+git clone --recurse-submodules https://github.com/nohamelin/MasterPDFEditor-patch.git
+cd MasterPDFEditor-patch
+make
+```
+
+Output: `MasterPDFEditor.dylib`
+
+## Usage
+
+```sh
+DYLD_INSERT_LIBRARIES=/path/to/MasterPDFEditor.dylib '/Applications/Master PDF Editor.app/Contents/MacOS/Master PDF Editor'
+```
