rwebb55 What drivers are needed for a 385MC connected to MacBook Pro
None, if you are just using an application.
If you are building an application using ZWO's SDK, in addition to the libASICamera2.dylib, you will also need libusb.1.0.0.dylib.
If you are building a Sandboxed application, be sure to also tick the USB entitlement under "Hardware."
