How to Install Pl2303 Driver For Mac OS X
If you have a device that uses a Pl2303 USB to serial controller, you might be wondering how to make it work on your Mac. The Pl2303 chip is widely used in various devices such as USB serial dongles, embedded USB bridges in cellphones, GPS receivers, and more. However, the default driver for Mac OS X does not support this chip, and you need to install a third-party driver to use it.
In this article, we will show you how to download and install the Pl2303 driver for Mac OS X, and how to troubleshoot some common issues that might arise. We will also provide some links to other resources that might be helpful for you.
Download the Pl2303 Driver For Mac OS X
The first step is to download the Pl2303 driver for Mac OS X from the official website of Prolific, the manufacturer of the chip. You can find the download link here: https://www.prolific.com.tw/US/ShowProduct.aspxp_id=229&pcid=41 [^1^]
On this page, you will see different versions of the driver for different versions of Mac OS X. Make sure you choose the one that matches your system. For example, if you have Mac OS Big Sur (version 11), you should download the file named PL2303HXD_G_Mac Driver_v2.1.0_20210311.zip.
Once you have downloaded the file, unzip it and double-click on the .pkg file to start the installation process. Follow the instructions on the screen to complete the installation.
Allow the Pl2303 Driver For Mac OS X
Depending on your system settings, you might need to allow the Pl2303 driver for Mac OS X before you can use it. This is because Mac OS X has a security feature that requires user approval before loading new third-party kernel extensions.
To allow the Pl2303 driver for Mac OS X, go to System Preferences - Security & Privacy and click on the General tab. You should see a message saying that \"System software from developer 'Prolific Technology Inc.' was blocked from loading.\" Click on the Allow button to unblock it.
You might need to restart your computer for the changes to take effect.
Connect Your Device Using Pl2303 Driver For Mac OS X
Now that you have installed and allowed the Pl2303 driver for Mac OS X, you can connect your device using a USB cable. The driver should automatically detect your device and create a virtual serial port for it.
To find out which port your device is using, you can use a terminal command called ls /dev/tty.*. This will list all the available serial ports on your system. Look for one that starts with /dev/tty.Repleo-PL2303-xxx or /dev/cu.Repleo-PL2303-xxx, where xxx is a number. This is your device's port name.
You can use any serial communication software to access your device through this port. For example, you can use screen or minicom in terminal, or you can use a graphical application such as CoolTerm or SerialTools.
Troubleshoot Pl2303 Driver For Mac OS X
If you encounter any problems with using the Pl2303 driver for Mac OS X, here are some possible solutions:
Make sure you have downloaded and installed the correct version of the driver for your system.
Make sure you have allowed the driver in System Preferences - Security & Privacy.
Make sure your device is powered on and connected properly.
Make sure your device's baud rate, data bits, stop bits, parity check, and flow control match with your serial communication software's settings.
Try unplugging and replugging your device or restarting your computer.
If none of these work, you might have a counterfeit Pl2303 chip that is not compatible with Prolific ec8f644aee
