# One Click Installers for MacOS
This document provide the details to build one click installers for MacOS. To manually build h2ogpt on MacOS follow steps at [README_MACOS.md](../../docs/README_MACOS.md).
**Note**: Experimental and still under development.
## Prerequisite
- Need conda installed inorder to run the build script.
- We use `PyInstaller` to build one click installer, it doesn't support cross platform builds. So the installers can
be only built from Mac Machines.
- Install tesseract & poppler on your Mac Machine
## Build
### Debug Mode (for one click installer developers)
- Clone `h2ogpt` from https://github.com/h2oai/h2ogpt.git
- Create conda environment and installer all required dependencies, consult [build_mac_installer.sh](build_mac_installer.sh) for more details.
- Run below commands to build the installer
```shell
cd h2ogpt
pyinstaller ./dev_installers/mac/mac_run_app.py -D -w --name=h2ogpt-osx-m1-cpu-debug --hiddenimport=h2ogpt --collect-all=h2ogpt --noconfirm --recursive-copy-metadata=transformers --collect-data=langchain --collect-data=gradio_client --collect-all=gradio --path=${CONDA_PREFIX}/python3.10/site-packages --collect-all=sentencepiece --add-data=./Tesseract-OCR:Tesseract-OCR --add-data=./poppler:poppler
```
### Deployment Mode
- Clone `h2ogpt` from https://github.com/h2oai/h2ogpt.git
- For CPU only installer, run below commands to build the installer
```shell
cd h2ogpt
. ./dev_installers/mac/build_mac_installer.sh
```
- For MPS (GPU) supported installer, run below commands to build the installer
```shell
cd h2ogpt
BUILD_MPS=1 . ./dev_installers/mac/build_mac_installer.sh
```
## Run
From MacOS finder, go to `h2ogpt/dist/` and double-click on the installer (i.e `h2ogpt-osx-m1-cpu`). |
