Foolish of me to update without verifying compatibility. Until now Mac OS and Firestudio have been rock solid.

Upon upgrading, I now get flashing red/blue. I've walked through manually uninstalling & reinstalling multiple times - same result.

Late 2013 iMac, running 10.13.4

Any help would be greatly appreciated.

Thank you

Apple introduced a new feature in High Sierra that if goes unchecked will not allow installation of driver kext files into your system.

Please read this article which may resolve your issue: https://support.presonus.com/hc/en-us/articles/115005456483-Installation-Issues-with-Universal-Control-on-High-Sierra-Mac-OSX-10-13

Also depends on which FireStudio you have. Looking at your account you have no products registered. Please take a moment to do that.

This only applies to FireStudio Project, Mobile, Tube, Lightpipe, SL1602, SL2442 and SL1642.
