This is because your Rane TTM 57SL has an older firmware version installed. Download and install Scratch Live 2.3.3 from here Scratch Live Downloads Archive. After installing Scratch Live 2.3.3 go to the Setup Hardware tab and select to 'Update Firmware.' The Rane TTM 57SL should now be recognized by Scratch Live 2.4.0 and above.
**Update - El Capitan is now supported in Serato DJ 1.8**
Support is hardware dependent and there are two minor known issues so please read here for more information.
----------------------------------------
Serato DJ and Serato DJ Intro do not currently support Mac OS X El Capitan (10.11).
We do not recommend updating to El Capitan. We are currently investigating some early reports of serious compatibility issues with hardware connectivity and audio. We're working hard to ensure stability with this OS as soon as possible and there will be updates that add support in the near future.
If you have already updated and are experiencing issues, please contact the Serato Support Team so we can help.
For any other questions, get in touch on Facebookor Twitter.
