This installer will install both the RealSimGear Plugin for X-Plane 11 as well as any necessary USB drivers and now supports Big Sur and Monterey

The install process is a multi-step process at this point due to the way Apple requires device drivers to be installed. Please make sure your RealSimGear hardware is connected to your Mac and powered on before starting the install.

Plugin Install

1. Download the MacOS X-Plane 11 Installer. Typically the file is saved in your "Downloads" folder as "".

2. Find the file downloaded in step 1, double click on the "" file which will extract the "

3. Double click on "" which will start the install.

4. You will likely be presented with a warning about an application downloaded from the Internet, you will need to click "Open"

5. On the main page, click "Next"

6. Choose the location where you have installed X-Plane, typically at the root of your user folder, and click "Next".

7. In the Install options, leave the "RSG Hardware Enable for Generation 2 devices" checked and if you have one of the products shown, G1000, GNS430 or GNS530, choose those options. If you have any other products, you can leave those unchecked (this is just to determine whether to copy the bezel files for these products or not). Click "Install".

The main installer will get to the finished page, but will also open the driver installer application. Click "Quit" on the main installer page.

USB Driver Install

When the Plugin installer finished, it will automatically start up the RSG Hardware Enabler. This enabler will detect and display the RealSimGear hardware found in order to determine what driver to install.

If you see a screen like this that indicates "These devices do not require driver from RSG Hardware Enabler" and/or the "Install or Update WCH Drivers" is shown, you can simply quit the RSG Hardware Enabler application by choosing Command+Q or click the red dot.

If you are using RealSimGear hardware that is based on the WCH USB chip (the one that gave us problems in the past for Big Sur), you will see the screen below indicating "Requires Driver Installation". If so, proceed with the install steps below.

1. Click "Install or Update WCH Drivers"

2. You will likely be presented with a "System Extension Blocked" message. Choose "Open Security Preferences"

3. This will open up your MacOS Security Preferences. First click on the lock icon in the lower left corner and provide your password to unlock this screen. This will cause the "Allow" button to become clickable, click "Allow".

4. You will get yet another warning message, click "OK"

5. After install, you should get the "Driver Installed" message, click "OK"

6. You will see the RSG Hardware Enabler which now should show "Supported by Hardware Enabler". You can simply close out of the RSG Hardware Enabler by doing Command+Q or click the red dot.

The installer normally will install the latest CommandMapping.ini files, however due to timing, you may want to check our "Just the Downloads" page for any updated CommandMapping.ini files.
