Matrix software is updated over the network, usually from your DAW.
Please register Matrix using the number only, do not include letters or leading zeros.
Download the latest console software and support file .zip from your user account My Products section and follow the included instructions.
The console software .jar file and Remote app (within the support .zip) are separate applications with different version numbers but should be installed concurrently and meant to be paired with each other. In otherwords, download and install all the files from the same row at once.
If you have problems updating on macOS due to Java or other security issues, you will find Windows to be easier and more reliable for updates in general.
