    After installing this from the sister site it gave a "No License Found" error pop up. I followed the instructions 100%, not sure why it didn't take.

    Like it says in the instructions, before starting the app I ran these in terminal like usual, and when it didn't work I tried Sentinel.
    sudo codesign -f -s -
    sudo xattr -cr
    sudo xattr -r -d com.apple.quarantine
    sudo codesign --force --deep --sign -

    Anyone know how to get it working?

    M1 Max Mac Studio 2022 running Sequoia

    Thanks for any help!

    i'm not using this, but I looked for a little info anyway. This is what was suggested and confirmed to work by a few others: Make sure you have the latest mediabay and library manager installed. Install Cubase and then either follow the instructions in the nfo to the letter OR run the iamdumb Steinberg patcher.

    There was an updated patcher from iamdumb released at the end of March. I'd probably just use the patcher.
