How do I fix this?
Hi @dbutler23608 welcome to the Waves Forum 
This may be because your Mac’s graphics card does not support ‘Metal’, which is required for V12 plugins.
Please refer to this link to learn more and rollback the plug-in version.
If any further assistance is needed, I suggest contacting our TechSupport team to assist according to your setup.
