LM809 User Manual 

3.2.

Uninstalling the MAC OS Driver 

Please follow the below steps to uninstall the LM809 driver on a MAC host computer. 

Step 1 :

 

Run the uninstall.command script in the same folder the driver is extracted. 

Step 2 :

 

You would need the root password to uninstall the driver. Enter the password 
when prompted in the terminal 

Step 3 :

 

Once the password is provided the script will uninstall the driver. 

Note :

 

Please DONOT delete the network interface (en2, en3 or similar) created in the network 
preference because MAC does not recreate this interface when the driver installation is 
executed the next time. It may become difficult to get the LM809 working if the network 
interface is deleted.
