We’ve got our ear to the streets and it seems that many plugin can’t pass validation, even from big software giants like Native Instruments and Arturia. In Native Instruments case, there are beta drivers available for download to help fix the issue.
And in case your other third-party plugins aren’t working you can follow this workaround to help validate your beloved AU’s. Please note that it does require you to do some system software tampering. Use at your own discretion. It seems to have worked for some users but it may cause other issues that are unkown at this momment. So we repeat, use at your own discretion.

The best way to stay protected is to not update to El Capitan (even though it looks all shiny and pretty). And remember, if it ‘aint broke to fix it!
