+# 1. Remove Conda environment
+conda deactivate
+conda remove -n deepseek-ocr --all
+
+# 2. Uninstall Python packages (if installed in system Python)
+pip uninstall torch torchvision torchaudio accelerate -y
+pip uninstall -r requirements-mac.txt -y

+# 3. Clear Node.js frontend build
+cd frontend
+rm -rf node_modules
+rm -rf dist
