Attention 注意

.app文件还未签名，因此可能要自行编译才能用在自己的mac上。

手动编译方法：

1. 如果没有，先安装pip：

• 先下载一键安装脚本：curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
• 然后用python运行，推荐使用python3：python3 get-pip.py

2. 安装pip2app：pip3 install py2app
3. 利用cd命令进入项目所在文件夹，然后利用py2app转换成.app文件：python3 setup.py py2app

自动编译方法：

直接运行项目文件夹内的setup.sh：./setup.sh。注意，可能需要先给予权限：chmod +x setup.sh。

Introduction

The main idea of the script is using sudo pmset -a GPUSwitch to switch GPU of your Mac.

It's only been tested on MacBook Pro (16 inches，2019).

There are four ways to use the program.

Shell Script

You can just run ./chgpu.sh or configure the environment variables for it.

Don't forget to run chmod +x chgpu.sh before if you have not.

Python Script

You can run python3 chgpu.py if you have installed Python 3. Note that Python 2 is not supported.

Binary file

You can download and run the binary file chgpu. In general, you can double-click it to run it. It may take a while to load.

GUI binary file

You can download and double click to run the app Switch GPU for Mac.app. If it doesn't work, right click it and then run. It's very intuitive, so I don't think you need a tutorial.
