Is CoGe compatible with El Capitan?

Yes, basically it is from version 1.6.3, but if you are running into any issues with CoGe on OS X 10.11, don't hesitate to get in touch with me.

For the best performance on fullscreen, make sure the "Displays have separate Spaces" option in the "Mission Control" section of System Preferences is disabled when using external displays.

General Issues

Quartz Composer effects and Core Image filters are leaking memory in most of the circumstances, this is a system-wide general issue on OS X 10.11. We suggest to use ISF filters instead of Core Image and Quartz Composer, whenever it is possible.

Known issues

  • Core Image blend modes are crashing - fixed in CoGe 1.6.3.1
  • The Cube Transition is no longer exists on OSX 10.11
  • Some QC based Dry/Wet modules are no longer working on OSX 10.11
  • MIDI Clock BPM may not be calculated right due some CoreAudio issues on OSX 10.11


Some QC modules seems to not working anymore on OSX 10.11 because of some OSX Core Image bugs:

  • ZoomEcho - fixed in CoGe 1.6.3.1
  • Iterator Cube - fixed in CoGe 1.6.3.1
  • Iterator Cylinder - fixed in CoGe 1.6.3.1
  • Iterator Sphere - fixed in CoGe 1.6.3.1
  • qVortex - fixed in CoGe 1.6.3.1
  • Overlay with Opacity - fixed in CoGe 1.6.3.1
  • Blazed Trails
  • Echo


The following Quartz Composer effects leaking memory which sooner or later results in a crash:

  • Kaleidoscope - use the Core Image Kaleidoscope effect instead


Some 3rd party QC FX not working, because of some new Core Image/Quartz Composer bugs:

  • v002 Optical Flow with Feedback
