# Step 1: Install Xcode command line tools xcode-select --install /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" Step 3: Install Qt Framework (macOS uses Qt5 for best stability, though Qt6 works) brew install qt@5 Step 4: Install CMake (build tool) brew install cmake Step 5: Clone the repository git clone https://github.com/yapid/QmodMaster.git cd QmodMaster Step 6: Set Qt environment variables (adjust path if using Qt6) export PATH="/usr/local/opt/qt@5/bin:$PATH" export LDFLAGS="-L/usr/local/opt/qt@5/lib" export CPPFLAGS="-I/usr/local/opt/qt@5/include" Step 7: Build the application mkdir build cd build cmake .. make Step 8: Run the app (from build folder) ./QmodMaster

# When running CMake, specify the architecture cmake -DCMAKE_OSX_ARCHITECTURES=arm64 .. make clean make This is not a Mac error, but a slave error. However, new users panic. Fix: Remember that Modbus addresses are zero-indexed in QmodMaster. If your PLC manual says "Register 40001," enter 0 in the address field. If it says "Register 40010," enter 9 . Issue 5: High CPU Usage If QmodMaster spikes your CPU to 100% on a MacBook, you likely have "Continuous Poll" enabled with a 1ms timer. Fix: In the transaction row, increase the "Timer" to 100 (100ms) or enable "On demand" polling using the "Read Once" button. Part 5: QmodMaster vs. Other Modbus Tools for macOS To understand if QmodMaster is right for you, let's compare it to the competition. # Step 1: Install Xcode command line tools

To keep the app accessible, run:

Introduction In the world of industrial automation, building management, and embedded systems, the Modbus protocol remains a gold standard. Whether you are a field technician commissioning a Programmable Logic Controller (PLC), an engineer testing a new sensor array, or a student learning SCADA systems, you need a reliable tool to read and write data. Enter QmodMaster . However, new users panic
