2. Mac - License not Found

The “License not found” will appear if the file mph.license and/or hardware.id files are missing from the /MP/Host folder.

Or if using a Mac OS older than MacOS Mojave.

First, ensure you have both files in the MP Host folder as shown here:

The hardware.id file is generated automatically when you run the MP Host plugin.
The mph.license file should be downloaded from the user portal.

Do not rename the hardware.id and mph.license files. 
If the filenames are not exactly as shown above, you will get the error "License not found"

If you believe your license is generated ok, on the new Mac computer, strict permissions may be the issue. You can try the following in a terminal

sudo chmod 777 ~/Library/Application\ Support/MP/Host

It will ask for your password and then enter. 

The terminal should not produce any output. If it produces a message then there may something wrong with the command issued.

Then try opening the MPH again.

Please note that if the license is not found, then it will not allow the hardware controller to be connected to the MP Host software.
