9. Mac - "Invalid mph.license" message

If you get a message on the left bottom corner of the MP Host that the license is invalid it means that the  mph.license  file was not generated for that computer. 

 You can use the License Manager application (recommended) to create a new license. Download it from the user portal. 

 The hardware.id file is a digital signature of your computer and your mp controller combined, so it is passed to our user portal to generate a license. 

 Alternatively, if you have copied the  hardware.id and/or the mph.license  file from another computer (perhaps using the Mac Time Machine) delete both the  mph.license  and  hardware.id  files and run the MP Host in the DAW to create a new  hardware.id  file. 

 Unload any instances of the MP Host and then load one MP Host in the DAW. It will create the hardware.id file automatically. 

 Then, log on your user portal account (see email when you purchased the MP Controller) and upload the hardware.id  file to generate a new  mph.license and download it. Then place it in the /MP/Host folder as shown below: 

 The  hardware.id  and  mph.license  files should have these 2 exact names.
