I've been using the 64 bit version of Sylenth perfectly with Logic for a few months now. After I updated to Sierra and opened up Logic all of my plugins got re scanned, but Sylenth says it couldn't be opened. This is the main synth that I use and would really like to get it working again immediately. Any suggestions are appreciated.
MacBook Pro (Retina, 15-inch, Early 2013), macOS Sierra (10.12)
Obviously it could be a compatibility problem. But I would try this just to be sure
csrutil disableI tried that and under compatibility in the plugin manager it still says "couldn't be opened". I've also tried uninstalling and then re installing the plugin. Is there anything else I can do?
Only the obvious - contact them and see if they know or roll back your OS.
Sorry ry that's all I know
