Question

My FireStudio Project / Mobile Isn't Working on OS X 10.10 Yosemite

Answer 1

After upgrading to Yosemite you will need to uninstall Universal Control and then reinstall version 1.7.2. Your FireStudio interface should be working after doing this.

Please follow our knowledge base guide on uninstalling and re-installing your FireStudio files/drivers:
