Master PDF Editor Patch
Bypasses license validation for Master PDF Editor 5.9.98 using inline hooking via 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
git clone --recurse-submodules https://github.com/NohamR/MasterPDFEditor-patch.git
cd MasterPDFEditor-patch
make
Output: MasterPDFEditor.dylib
Usage
To use the dylib, you have two options:
Option 1 — DYLD_INSERT_LIBRARIES (requires SIP to be turned off; refer to Apple's documentation):
DYLD_INSERT_LIBRARIES=/path/to/MasterPDFEditor.dylib '/Applications/Master PDF Editor.app/Contents/MacOS/Master PDF Editor'
Option 2 — Permanent injection (uses optool to inject the dylib into the app bundle):
./inject.sh /path/to/MasterPDFEditor.dylib '/Applications/Master PDF Editor.app'
