To install the HiDPI settings on macOS, open the terminal and run the command: ```bash bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh)" ``` If you encounter a connection error, download the installation package from GitHub or CSDN. After downloading, unzip and double-click `hidpi.command`. If prompted that it cannot be opened, go to Mac settings → Privacy & Security to allow it. During installation, enter '1' to proceed, then '3' and provide your Mac's password. Choose the appropriate display resolution for your monitor (e.g., the 4th option for a 2K display). Once the process is complete, restart your Mac. After rebooting, check the resolution settings to select a comfortable option, such as 1680x945 (HIDPI).

Open the terminal in macOS

After entering this command, press the Enter key.
```
bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh]]"
```
If you see curl: (28) Failed to connect..., we cannot install via command, we can install by downloading the installation package.
Download the installation package
- Download from GitHub: https://github.com/xzhih/one-key-hidpi
- Download from CSDN: https://download.csdn.net/download/network_dream/90273442
After downloading, unzip and install,
- Double-click hidpi.command
- If it shows unable to open, go to Mac's settings → Privacy & Security → Open anyway.
- Installation
  - Enter 1, press the Enter key
  - Enter 3, press the Enter key, and input your Mac's startup password.
  - Here, choose the refresh rate of your monitor. Since I am using a 2K monitor, I choose the fourth option. If you see [Process completed], it means the installation was successful.
Restart your Mac.
Compare before and after installation, open Settings → Resolution. The left side shows the settings before installation, and the right side shows the settings after installation. Choose a suitable one on the right; I am using 1680x945 (HIDPI), which looks more comfortable overall.
