NOTE: The RealSimGear USB drivers ARE NOT compatible with the latest MacOS, Big Sur. If you plan to use RealSimGear hardware on a Mac, DO NOT upgrade to Big Sur until further notice.
When using some of the newer RealSimGear hardware on a Mac, customers will need to install updated USB drivers. As of June, 2020, the hardware that requires this USB driver include:
G1000 PFD/MFD units shipped after April 1, 2020
** Additional units will begin to make use of this new USB driver in the future.
A word on Mac security. With MacOS Catalina, Apple has tightened their grip on what types of drivers can be installed and will be supported going forward. Because of that, when installing the RealSimGear driver, you will likely be presented with a warning screen such as this:
If seen, you simply need to 'Open Security Preferences' and allow the RealSimGear Extension in the dialog.
With that caveat, the install is very straight forward:
Download the RealSimGear USB Installer Mac from HERE.
Find the file downloaded in Step 1 (typically your 'Downloads' folder), and double click on it.
Follow the prompts until it finishes. NOTE: It can take a minute or so to finish the install, so if it appears to have hung, just wait a bit longer, it will eventually finish.
You may need to disconnect and reconnect the USB cable to the RealSimGear unit
You may need to reboot your Mac to get the driver to properly load.
